PRDM paralogs are required for Meckel's cartilage formation during mandibular bone development

Mandibular bone development depends on the formation of a cartilaginous anlage Meckel's cartilage derived from neural crest cells (NCC) and intramembranous ossification or direct differentiation of NCCs toward osteoblasts. Wnt/β-catenin signaling drives osteogenic vs chondrogenic differentiation and must be tightly controlled during the differentiation of osteochondroprogenitors. Chromatin remodelers add hierarchal regulation to the activation and repression of crucially timed gene regulatory...
