Rostral Endochondral Facial Bones

Rostral endochondral facial bones are endochondral bones derived from cranial neural crest cells. Endochondral ossification involves a cartilaginous template that is replaced by or remodeled into bone by processes that involve several coordinated steps that can include calcification of the cartilage matrix, hypertrophy of chondrocytes followed by apoptosis, resorption of calcified cartilage, recruitment of osteoblasts, and deposition of woven bone (and later lamellar bone) on the surface of mineralized cartilage residues.

Endochondral ossification in the head starts at E16.
