abstract
The type IA bone morphogenetic protein receptor (Bmpr1a), encoded by 11 exons and spanning about 40 kb on chromosome 14 in mice and chromosome 10 in human (Derynck & Feng, 1997; Mishina, Hanks, Miura, Tallquist, & Behringer, 2002), is an essential receptor for BMP signaling. This chapter focuses on the current understanding of the role of Bmpr1a in cartilage development and endochondral ossification, including formation of the mesenchymal condensation, chondrocyte differentiation and maturation, and endochondral bone development.
