🦴 Bone-on-a-Chip Is Redefining Bone Biology Research Microengineered Bone Models: Advances and Applications of Bone-on-a-Chip Technology 📖 Journal of Biological Engineering (2026) 🔗 DOI: 10.1186/s13036-026-00703-3 For decades, bone research has relied on a trade-off: 🔬 2D cultures are scalable but physiologically unrealistic. 🐭 Animal models capture complexity but often fail to predict human responses. A new comprehensive review highlights how Bone-on-a-Chip (BoC) technology is emerging as a powerful bridge between these worlds. By combining microfluidics, biomaterials, tissue engineering, and real-time sensing, BoC systems aim to recreate the dynamic bone microenvironment in vitro. Why is this important? Bone is not simply a mineralized scaffold. It is a living organ composed of: • Osteoblasts (bone formation) • Osteoclasts (bone resorption) • Osteocytes (mechanosensing and remodeling control) • Vascular and marrow niches • Complex mechanical loading forces Replicating these interactions has been extraordinarily difficult using conventional experimental models. Modern BoC platforms now incorporate: ✅ Microfluidic perfusion ✅ 3D mineralized matrices ✅ Osteogenic and hematopoietic compartments ✅ Controlled oxygen gradients ✅ Mechanical stimulation ✅ Real-time biosensors These systems allow investigators to study bone remodeling under conditions that more closely resemble human physiology. One particularly exciting application is bone marrow niche modeling. Recent devices successfully maintain hematopoietic stem and progenitor cells while recreating vascularized marrow microenvironments, enabling studies of hematopoiesis, drug toxicity, and niche biology that were previously difficult to perform in human systems. Another major advance is bone metastasis modeling. Bone is the preferred metastatic site for breast, prostate, and lung cancers. BoC platforms have reproduced critical features of metastatic colonization, including: 🔹 Tumor dormancy 🔹 Perivascular niche interactions 🔹 Oxygen gradients 🔹 Drug resistance mechanisms These models provide unprecedented opportunities to investigate early metastatic events and evaluate anti-metastatic therapies. The review also highlights the growing role of BoC systems in drug discovery. Researchers have developed: • Osteon-mimetic chips for osteoporosis drug screening • AI-assisted image analysis pipelines • Hydroxyapatite-coated microfluidic scaffolds • Personalized bone regeneration platforms using stem cells These advances are moving bone research toward precision medicine. Yet significant challenges remain. Current platforms still struggle to fully reproduce: ❌ Native bone hierarchy ❌ Osteocyte networks ❌ Long-term remodeling cycles ❌ Functional vascularization ❌ Immune system integration ❌ Physiological mechanical loading The next generation of BoC systems will likely integrate multi-organ interactions, patient-derived iPSCs, advanced bioprinting, and AI-powered analytics to create truly predictive human bone models. Bone-on-a-Chip is rapidly evolving from an engineering curiosity into a translational platform that could transform osteoporosis research, cancer metastasis studies, fracture healing, regenerative medicine, and drug development. #BoneOnAChip #OrganOnAChip #BoneBiology #RegenerativeMedicine #Microfluidics #DrugDiscovery #Osteoporosis #BoneMetastasis #TissueEngineering #PrecisionMedicine #Bioengineering #AgingResearch #StemCells #AIinBiology #TranslationalMedicine

Progress in treating nervous system injuries has been historically limited by a lack of human‑relevant models. Neural repair experiments on animals "fall short in replicating human-specific features such as long axonal architecture, species-specific gene regulation, and cellular diversity, all of which are critical for understanding neural repair in humans." In this new review, @RutgersBioSci researchers highlight how human induced pluripotent stem cell (iPSC)–based models are changing what's possible for this field. doi.org/10.1016/j.pneurobio.… From 2D cultures and 3D organoids to microengineered injury platforms and patient‑specific cell types, these models are revealing key regulators of neurite growth, clarifying how disease‑linked mutations disrupt axonal integrity, and accelerating the discovery of neuroprotective and pro‑regenerative compounds. @manasiagrawal1, Meghal Desai, Shruti Ghumra, Yashashree Bhorkar, and @SahooLab discuss how iPSC‑derived neurons, glia, Schwann cells, and neuromuscular junctions are advancing our understanding of remyelination, axon‑glia interactions, and circuit‑level repair—areas where translation from experiments on animals has repeatedly fallen short. Investing in human‑relevant platforms offers the best chance of developing therapies that restore function after nervous system injury and for furthering the field of regenerative neuroscience.

#UNC is a low-talent football team. 70/105 players are new 16 UNC football players departed via the transfer portal during the 2025 spring window The #CarolinaClickBaitBrigade & the #UNCFanBase, who kept pushing the idea that the 2025 #TarHeels would win 7 games due to a #weakschedule, missed the obvious that #NorthCarolina was weaker than the other #ACC programs that they looked down their arrogant noses upon Belichick is making the best of a huge dung burger. He and his GM buddy Lombardi may land some players in recruiting and pick off a transfer, but in the end, neither the coach nor the GM is likely to be a long-term program builder. And when they both leave Chapel Hill, there will not be an ACC Championship, and they are not expected to have winning records against either #NCState or #Duke. Will #UNC be left with #SteveBelichick as the head coach, or will some Adult over in Chapel Hill finally stand up and make logical decisions about the #UNCFootballProgram, which has been in a tailspin of mediocrity since December 4, 1997, the day @CoachMackBrown left for Texas. Carolina has not won a meaningful college football game since beating Clemson in Death Valley on November 8, 1980 - 16,387 days - the afternoon when the Tar Heels clinched their last #ACC Championship. @CoachJonSumrall should be the head coach at UNC right now. #DarianMensah could have been the #TarHeels QB1. Instead, this #TarHeel football team will most likely finish the 2025 season with a below .500 record, a 74-year-old head coach, and no logical plan forward beyond 36 months. The last three games of the 2025 season are against Wake Forest, at home against Duke, and at NC State. MAYBE the Tar Heels can compete with the Demon Deacons, but on the road, and after the gauntlet of losses that will come over the next two months, the likely record against the traditional #Big4 rivals is bagel and 3. Again, the clown prince, #JonathanPreyer, is the guy who microengineered this debacle. He turned UNC Football into the environmental equivalent of #Bhopal (1984) or #Chernobyl (1986). Nice job, JP.

Giant corporations like McDonalds have micromanaged and microengineered every second of a customer's experience in their restaurants. From the ingredients, to the visuals, to the smell, to the marketing. They deliberately make their foods salty so we get thirsty. Then they make their sodas super-sweet with sugar so not only does it addict us, but makes us dehydrated and makes us more thirsty. Every single second has been tweeked to make us buy their products once and keep coming back forever!
