About Dr. Xin Zhou
Dr. Zhou is a developmental bone biologist. Her research interests are the transcriptional control of osteoblast differentiation and the origins of osteoblasts. Her work in Dr. Benoit de Crombrugghe’s lab led to the discovery of Osterix (Osx, Sp7), a master transcription factor essential for osteoblast differentiation and bone formation, both during embryonic development and post-natal bone growth and homeostasis. Her recent work using cre/reporter lineage tracing mouse models revealed that mature chondrocytes are a major source of osteoblasts in endochondral bone formation during development and postnatal growth. This finding has advance our current understanding of endochondral bone formation process with implications for the control of bone homeostasis and the interpretation of the underlying pathological changes of bone diseases. Currently, she is working on elucidating the underlying mechanism of chondrocytes to osteoblasts trans-differentiation and exploring the potential signaling pathways regulating this process.
