Early determination of the dorsal-ventral axis in endochondral ossification in mice.

ABSTRACT: Endochondral ossification is a highly coordinated process involving distinct progenitor cell populations within the mesenchymal condensation and subsequent cartilage anlage and perichondrium, all of which drive skeletal formation. Cell-type specific lineage tracing conducted to understand fetal bone development has revealed various fates of early skeletal cells. However, the underlying continuous and precise cellular dynamics of fetal skeletal cells, particularly along the dorsoventral axis, remain unclear. Here, we show that spatiotemporally specific skeletal progenitor cells in the early developmental stage contribute to the dorsal-ventral axis in a manner that is strictly determined during initial developmental stages.
