K Mizuhashi , M Nagata , Y Matsushita , W Ono , N Ono

To read the full abstract: J Bone Miner Res 2019;34(8):1387–1392.In brief: Cell tracing of the growth plate chondrocytes most adjacent to the perichondrium demonstrate that they transit into the metaphysis and contribute to the pool osteoblasts and reticular stromal cells of the bone marrow during growth in young mice.Commentary: Borderline chondrocytes are the growth plate chondrocytes located as a ...
