RESEARCH INTERESTS

Focused on the study of stem cell biology, bone development, and regenerative medicine for more than 20 years. Published 33 orthopedic research papers as first or corresponding author in Nat Med, Bioact Mater, Dev Cell, PNAS etc. with total IF>310 and citations >3000. His research team consists of 7 permanent members and 20 doctoral and master's students.

Obtained three projects of National Natural Science Foundation of China including a key joint project (Guangdong) and two key projects of Chongqing Science and Technology Bureau. His previous work on osteocytic Wnt signaling was selected as the outstanding research in the annual meeting by American Society for Bone and Mineral Research (ASBMR) in 2013, and was consecutively commented by Nature Reviews magazines. His research on Wnt and Notch signaling in orthopedics is at the forefront of the world.

Carries out translational study. He discovered the osteogenic microenvironments and established their 3D bioprinting system for integrative printing of hard materials and cells to reconstruct a bone development module with these microenvironments for bone regenerative repair. These microenvironments include functional cells and their decellularized matrix, secreted exosomes, microenvironmental factors, and small molecular drugs.

In addition, conducts research on the aging, degeneration, and regenerative rehabilitation of the sports system.

Research directions:

1. Molecular mechanisms on bone development and homeostasis

1) Basis and countermeasures for the prevention and treatment of bone fracture delayed union and nonunion

2) Basis and countermeasures for the prevention and treatment of bone loss caused by weightlessness

3) Bone degenerative disease and ferroptosis

2. 3D bioprinting and organoid bone construction

3. Development of bio-ink and biodegradable bone repair materials

4. Orientated differentiation, lineage specification, and spatial and temporal regulation of osteogenesis of stem cells/iPSC cells

5. Osteogenic drugs

6. Bone and aging

7. Skeletal biomechanics
