The Novel Zinc Finger-Containing Transcription Factor Osterix Is Required for Osteoblast Differentiation and Bone Formation

TL;DR: It is proposed that Runx2/Cbfa1-expressing preosteoblasts are still bipotential cells, because Osx null preostEoblasts express typical chondrocyte marker genes, and Osx acts downstream of Runx 2/C bfa1.
Journal ArticleDOI

Sox9 is required for cartilage formation.

TL;DR: The results identify Sox9 as the first transcription factor that is essential for chondrocyte differentiation and cartilage formation and Sox9 is identified as a regulator of the chondROcyte lineage.
Journal ArticleDOI

The transcription factor Sox9 has essential roles in successive steps of the chondrocyte differentiation pathway and is required for expression of Sox5 and Sox6

TL;DR: It is concluded that Sox9 is required during sequential steps of the chondrocyte differentiation pathway and is also needed to prevent conversion of proliferating chONDrocytes into hypertrophic chondROcytes.
Journal ArticleDOI

A new long form of Sox5 (L-Sox5), Sox6 and Sox9 are coexpressed in chondrogenesis and cooperatively activate the type II collagen gene

TL;DR: The data suggest that L‐Sox5/Sox6 and Sox9, which belong to two different classes of Sox transcription factors, cooperate with each other in expression of Col2a1 and possibly other genes of the chondrocytic program.
