The briefing
A proof‑of‑concept study in Nature reports that periosteal cells cultivated in simulated microgravity, or their secretome, enhanced bone mineralization in osteoporotic rats. The secretome’s effects were comparable to bisphosphonates and showed superior gains in cortical thickness, suggesting a potential alternative therapeutic avenue.
