science ๐ฆด Muscle cells are key to mending broken bones
A study revealed that muscle-resident fibroadipogenic progenitors (FAPs) help repair fractured bones. Led by Dr. Ugur M. Ayturk in the USA, researchers found these extra-skeletal cells are recruited after injury. Published on July 06, 2026, they showed 28% of healing callus osteoblasts came from Clec3b-lineage cells within three weeks. This discovery suggests these dormant cells are a promising therapeutic target to boost fracture healing. ๐ฆด
