The system incorporates key cellular components—stromal cells and endothelial cells—within biofunctional hydrogels seeded with patient-derived tumor cells, optionally supplemented with autologous immune cells. By accurately capturing the essential tumor microenvironment, the niche provides a physiologically relevant system that offers insight into tumor behavior, immune evasion, and drug resistance, outperforming classic suspension assays when it comes to cell viability, assay versatility, and clinical predictivity.
'Crown Bioscience is proud to unveil this high-content imaging-based 3D BMN platform that offers a unique and robust high-throughput drug screening in primary patient cells that allows testing of malignancies and toxicities at scale,' said Ludovic Bourré, Vice President, Research and Innovation, Crown Bioscience. 'Until now, bone marrow research has lagged behind solid tumor research due to lack of relevant in vitro models. With these BMN technological advances, we are now able to help researchers understand how cancer survives therapies once it reaches the bone marrow. This allows them to guide the selection of drug candidates with fewer off-target or bone marrow-related side effects and to overcome drug resistance mechanisms.'
Researchers can realize significant benefits with the BMN models including:
The use of more predictive ex vivo data to increase accuracy in cancer cell response
The ability to screen compounds for hematological toxicity earlier in the drug development process
Enhanced translational insight for more informed in vivo studies, helping to reduce animal use and speed up drug development
Enabling the creation of more effective, targeted treatments through adhesion-mediated drug resistance modeling
Unlocking new potential in stem cell, hematological malignancy, and bone-marrow-specific oncology studies
The introduction of the BMN platform seamlessly integrates into Crown Bioscience's expertise in 3D organoid-like cell cultures, drug resistance models, and AML mouse models and bridges a gap between in vitro and in vivo models.
Bourré said, 'This is a very exciting advancement for researchers and with this offering that integrates into Crown Bioscience's existing solutions, we're able to continually foster innovation and accelerate drug development.'

This Toyota Outsold the Corolla Hybrid and RAV4 Put Together
Toyota has been a hybrid leader for years, blending efficiency and reliability into some of the most popular cars on the road. From compact sedans to family SUVs, their electrified lineup continues to resonate with fuel-conscious buyers. But 2025 is already rewriting the script. The usual best-sellers—the Corolla Hybrid and RAV4 Hybrid—have been overtaken by an unexpected contender. This hybrid-only sedan has surged ahead, outselling both in the first quarter. If the momentum holds, it could mark a new era for Toyota's electrified future. In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from Toyota and various other authoritative sources, including the EPA and TopSpeed. In March 2025, Toyota moved an impressive 29,655 units of the Camry Hybrid—putting it well ahead of the pack. That single model outsold two of Toyota's usual hybrid heavy-hitters combined. The Corolla Hybrid notched 5,529 sales, and the RAV4 Hybrid added 14,524, bringing their total to 20,053. Even together, they couldn't close the gap. That's nearly 10,000 fewer units than the Camry Hybrid—a surprising margin. If you'd asked me which Toyota hybrid would be on top, I wouldn't have guessed this one. What makes the Camry's sales surge even more impressive is that Toyota's March numbers for the RAV4 include an extra 2,631 plug-in hybrids. Even with that boost, the RAV4 still couldn't close the gap. The Camry Hybrid, which doesn't even offer a plug-in option, managed to outsell the Corolla Hybrid and RAV4 Hybrid combined. No fancy charging port—just solid, old-school hybrid dominance. With numbers like these, it's easy to imagine a plug-in Camry being a runaway success if Toyota ever built one. We're not holding our breath, but how cool would that be? In the first quarter of 2025, Toyota sold an impressive 70,281 Camry Hybrids, more than a quarter of all its electrified sales. Out of 255,915 hybrids, plug-ins, and EVs sold, the Camry Hybrid stands head and shoulders above the rest. That kind of sales volume puts the Camry in a league of its own. It's not just leading the pack; it's outselling every other electrified Toyota model by a wide margin. The Camry Hybrid's sales have skyrocketed this year, but there's a twist. Back in Q1 2024, Toyota sold just 8,986 Camry Hybrids, but that number jumped to 70,281 in the same period of 2025. March was especially wild, with sales leaping from 2,424 units last year to 29,655 this year. The secret? Toyota now offers the Camry exclusively as a hybrid, so every single Camry sale counts toward their electrified totals. For the first time ever, the 2025 Toyota Camry is offered exclusively as a hybrid. Toyota has dropped the traditional gas-only engines, signaling a serious push toward electrified driving. It's a bold move for a model that's been a longtime bestseller, but the payoff is clear. By going hybrid-only, Toyota has made the Camry simpler, more efficient, and affordable, without cutting corners on performance. Even with the switch to hybrid-only, the 2025 Camry keeps its pricing competitive across all four trims. You can get into the base LE for $28,700, while the sportier SE starts at $31,000. If you want a bit more luxury, the XLE comes in at $33,700, and the top-tier XSE kicks off at $34,900. For a midsize sedan that delivers great fuel economy, advanced safety, and a comfy, tech-packed interior, the Camry offers solid value. Fuel efficiency has always been a major draw for the Camry Hybrid, and the 2025 model keeps that momentum going strong. The front-wheel-drive LE shines with an EPA-estimated 53 MPG city and 51 MPG combined, letting you cover up to 663 miles on a single tank. Even the all-wheel-drive LE isn't far behind, delivering an impressive 50 MPG combined and about 650 miles of range. That means whether you stick to two wheels or go all out, the Camry Hybrid keeps you going longer between fill-ups. The SE, XLE, and XSE trims dial back fuel economy a bit in exchange for extra features and stylish upgrades, but they still deliver solid efficiency. Front-wheel-drive versions hit around 47 MPG combined with a range of about 611 miles. All-wheel-drive models get between 44 and 46 MPG combined, offering roughly 572 to 598 miles before you need to stop for gas. With fuel prices always fluctuating, the Camry strikes a great balance for drivers who want strong performance without constant trips to the pump. Even the base Camry LE surprises with a well-equipped interior. You get an easy-to-use 8-inch touchscreen with wireless Apple CarPlay and Android Auto, plus a six-speaker audio system that sounds great. Inside, there's a 7-inch digital instrument cluster, dual-zone climate control, push-button start, and wireless phone charging—along with five USB ports to keep everyone connected. Rear passengers enjoy their own air vents and plenty of legroom for a comfortable ride. Step up to the XLE or XSE, and the luxury factor kicks in. Dual 12.3-inch screens take over the dashboard, leather-trimmed seats come with heating (and optional ventilation), plus ambient lighting sets the mood. You can also opt for a nine-speaker JBL premium audio system that transforms the cabin into a mini concert hall. It's a sweet blend of tech, comfort, and style that makes every drive feel special. When you look at specs, price, and everyday practicality, it's easy to see why the Camry is winning over so many buyers this year. It packs more horsepower than both the Corolla and RAV4 Hybrids, while still delivering impressive fuel economy and a best-in-class range of up to 663 miles. The Camry also offers more features than the Corolla and comes in well below the RAV4 Hybrid's starting price of $32,300. Sure, the RAV4 boasts extra cargo space and some off-road chops, but the Camry balances comfort, efficiency, and affordability in a way that's hard to beat. The Corolla Hybrid is definitely the budget-friendly pick in Toyota's hybrid lineup, starting at just $23,825—but with only 138 horsepower and a smaller 13.1-cubic-foot trunk, it's a bit limited in what it offers. The Prius is another strong contender, boasting up to 57 MPG combined and a starting price of $28,350, just under the Camry. There's also the Prius Prime plug-in, which offers 44 miles of all-electric driving, though it starts at a steeper $33,375. But if you're after an efficient, spacious, and well-rounded sedan that balances price, power, and practicality, the 2025 Camry Hybrid makes a seriously strong case for itself.

Weber Grill Restaurant to be first tenant in Orland Park downtown development
Weber Grill Restaurant will open a location in Orland Park next year, becoming the first tenant announced for the village's downtown development project northwest of La Grange Road and 143rd Street. The company is owned by the same family that makes the grills, which are used to prepare meals at the restaurants. Weber Grill will build an 8,500-square-foot space at the southwest corner of La Grange and 142nd Street, said Ramzi Hassan, president of Edwards Realty Co. Orland Park-based Edwards was selected by the village to develop that has been called the Main Street Triangle project. 'This is exactly the type of tenant we envisioned when we first imagined downtown Orland Park,' Hassan said in a news release announcing the restaurant's plans. 'Weber Grill represents a high-quality, experience-driven restaurant that aligns perfectly with our vision to create a dynamic, walkable destination for the community.' Planned to open next spring, the restaurant will feature indoor and outdoor seating, as well as a hands-on cooking school offering both public and private cooking classes, according to Weber Grill Restaurants. The company also has restaurants in downtown Chicago and suburban locations in Lombard and Schaumburg. 'We're thrilled to bring the unique Weber Grill experience to the new downtown Orland Park,' Jon Crost, chief operating officer of Weber Grill Restaurants, said in a news release. 'This location allows us to connect with a vibrant and growing community while being part of a visionary redevelopment that emphasizes both quality and community.' Hassan said Friday that Weber 'is a really good brand that's a household name,' and its decision to open in Orland Park could attract other tenants. He said that Weber was looking to the Orland Park market for a restaurant, but 'they were more interested in the type of development they are joining.' 'They had to find the right fit,' Hassan said. He said Edwards has been very selective about the users and businesses coming in to the development, and said the Weber Grill Restaurant could be destination drawing customers from beyond the Orland Park area. 'It's not like they have 300 restaurants all over the country,' Hassan said. Edwards plans to develop more than 140,000 square feet of entertainment, retail and office space. No residential space is planned. An expansion of Crescent Park, to be renamed Heroes Park, is included, and what is now a stormwater detention pond in the northeast corner of the triangle would be enhanced with fountains. The company and village held a ceremonial groundbreaking for the downtown project in March. Edwards owns and operates Orland Park Crossing, a retail center northeast of La Grange and 143rd, directly to the east of the downtown development. The downtown development would be situated around the Ninety7Fifty on the Park apartments, University of Chicago Medicine Center for Advanced Care, a parking garage and the 143rd Street Metra station. Hassan said he expects Edwards to break ground in spring on space for a second tenant, which would be on a site west of La Grange on the south side of 142nd.

California insurance crisis could have dire consequences for affordable housing
Insurance bills have always been on the high side for Episcopal Community Services, a San Francisco nonprofit that operates more than 2,000 units of permanent supportive housing and serves a population insurers deem risky. But over the past few years, ECS has seen insurance costs skyrocket. Its premiums rose 84% last year, on top of 10% and 15% increases the previous two years. At the same time, ECS' deductibles quadrupled last year and reached $100,000 for some properties, forcing ECS to cover most of its own claims. Those rising costs were a factor in ECS' decision to lay off six employees this year, and staff members fear that continued increases could jeopardize essential but expensive ECS services, like the homeless shelter it operates or the seven hotels it leases for supportive housing. 'If we're gonna continue to operate the housing, we have to pay the insurance,' said Chris Callandrillo, ECS' chief program officer. 'We've got to get that from somewhere, and that burden is huge.' Across California, affordable housing developers say they're being squeezed by ever-rising premiums, increasingly convoluted coverage arrangements and deductibles so high that they're self-insuring for all but the most catastrophic losses. Advocates are pushing the federal government for relief in the form of subsidies for risk mitigation or the creation of a federally backed insurance product, but few solutions appear likely in the short term. According to an analysis of over 130 California properties financed by a key federal low-income tax credit and included in the national nonprofit Enterprise Community Partners' portfolio, median annual per-unit insurance expenses increased 142% from 2019 to 2024, from $409 to $989. From 2022 to 2024, some California affordable developers reported insurance expense increases as high as 500%. Without intervention, affordable housing providers say, these ballooning costs could force cuts to staffing or on-site services and imperil future projects at a time when demand for affordable units is as high as ever. The problem goes far beyond the affordable housing sector; statewide, insurers have sought perennial rate hikes, nonrenewed customers or ceased writing new policies as they grapple with wildfire-fueled losses and high construction costs. But over the past few years, insurance costs for affordable housing developments have been about 25% higher than for market rate developments in the same areas, said Jordann Coleman, senior vice president at Walnut Creek-based Heffernan Insurance Brokers, whose client base is 40% affordable housing. And affordable housing developers say they're especially vulnerable because they're already operating on razor-thin margins — and because unlike for their market-rate counterparts, the law limits their ability to pass on costs to tenants. 'Somebody's got to come up with a way to pay for that, and for us, it can't be rent,' said Linda Mandolini, CEO of Eden Housing, a Hayward developer with dozens of Bay Area affordable housing complexes. The amount Eden Housing has paid for insurance has risen every year since 2018, including a 20% jump this year on top of a 28% jump the previous year. Insurers have long considered affordable housing riskier to underwrite than market-rate housing — especially permanent supportive housing, where formerly homeless residents less used to living inside can spark fires or cause damage. But developers say insurance costs are out of step with claims, and they don't seem to take into account efforts to mitigate risks — such as hiring more security or replacing gas stoves with electric ones — or how affordable complexes can make neighborhoods safer and spur economic development over time. One insurer that writes policies for affordable housing developers declined to comment on its rationale for increasing premiums and deductibles, and another insurer did not respond to a request for comment. Before around 2020, it was possible to find a single insurer willing to underwrite an affordable housing provider's whole portfolio of properties, Coleman said. Now, she's sometimes working with up to 12 different insurers to piece together more scant coverage with higher deductibles — and each insurer has its own set of questions and restrictions. Coleman said she is increasingly reliant on more complicated risk-sharing arrangements, such as 'insurance towers' — Jenga-like stacks of policies where different insurers underwrite fractions of a single property (one of ECS' properties is underwritten by six insurers, Callandrillo said). In cases where clients have preexisting contracts that require lower deductibles than insurers are willing to grant, Coleman has also turned to deductible buy-down policies — additional coverage from a separate insurer that pays the difference in the case of a claim. 'The work is exponential, not just for us, but for our clients as well,' Coleman said. These days, it's rare that she has more than one option to offer a client. Most affordable developers are already working on shoestring budgets stretched thin by rising construction costs and still recovering from lower revenue from tenants who got out of the habit of paying rent during COVID-19. Because most expenses are nonnegotiables, such as payroll and maintenance, keeping up with insurance payments can mean dipping into funds earmarked for longer term projects. 'This is really depleting our property level reserve, our rainy day fund,' said Janelle Chan, CEO of East Bay Asian Local Development Corp., which has developed about 2,500 affordable units in Oakland. The nonprofit has diverted $12 million from its reserves over the last few years to pay for property expenses including insurance, increased utility costs and rent collection deficits, she said. As part of belt-tightening measures, the East Bay Asian Local Development Corp. is considering cutting community programming or stripping nice-to-have features from planned projects, Chan said. But if premiums stay high, affordable developers say, future projects could be in jeopardy if insurance — a prerequisite for securing loans — is just too expensive, or if developers' reserves have been too depleted to buy properties in the first place. 'We might have to put stuff on hold,' Mandolini said. Among Eden Housing's pipeline of 4,500 planned affordable homes is a complex for seniors at risk of homelessness in San Jose, converting the former Richmond Health Center into dozens of units of permanent supportive housing, and a 119-unit Liberation Park intended to revitalize a historically Black neighborhood in East Oakland. There's another even more serious risk: If mounting expenses cause developers to default, foreclosure can wipe out a property's low-income housing use designation — a more permanent setback for constructing affordable units. 'That's just a critical loss that can't be allowed to happen,' said Thom Amdur, senior vice president for policy and impact at Lincoln Avenue Capital, which invests in affordable housing across the country. Delays or defaults could threaten the region's ability to meet its housing goals. The Bay Area is required to plan to build close to 450,000 new units by 2031, of which 40% should be allocated for low- or very low-income residents, according to the state's Regional Housing Needs Determination. Affordable developers want the government to step in, either by subsidizing risk mitigation efforts or by stabilizing the insurance market through creating a federally backstopped insurance product or expanding FAIR plans — state-created insurers of last resort, such as the one in California — to cover more affordable housing. California lawmakers are considering a bill, AB1339, that would require the Department of Insurance to conduct a study on barriers to affordable housing insurance statewide. For now, developers continue to feel the squeeze. 'We're being asked to build more, and yet we are struggling to protect what we have,' Chan said. 'The candle's burning at both ends.'
