 (Tissue Regeneration, Vital Pulp Preservation and Tooth Development Research Group) 

Our research group focuses on applying stem cells and their derivatives combined with biomaterials to promote tissue regeneration, exploring pulp-capping materials for vital pulp preservation, and elucidating key molecules and signaling pathways in tooth development.

Direction 1: Our primary focus explores the regenerative potential of MSCs and their derivatives combined with biomaterials. Specifically, we employ dental-derived stem cells (e.g., SHED) and their paracrine factors, either loaded onto microcarriers or as standalone aggregates, to enhance functional pulp and bone regeneration in craniofacial and oral applications.

Direction 2: We develop novel biomaterials for vital pulp therapy, aiming to maximize inflammatory pulp repair and promote continued root development in young permanent teeth.

Direction 3: We investigate molecular mechanisms governing tooth development, identifying key regulatory pathways and novel factors influencing tooth morphogenesis and function.

RESEARCH AREAS

Tissue Regeneration

Our previous work has pioneered the development of optimized SHED aggregates and SHED-laden cryogel microcarriers for pulp regeneration, achieving functional vascularized pulp regeneration in vivo through enhanced stem cell functionality. In bone regeneration, we innovatively established a modular co-delivery system for BMSCs and HUVECs, enabling synergistic osteogenesis-angiogenesis with high cell viability. Building upon stem cell aggregate derivatives, we further engineered SHED exosome-modified polyester microspheres, which successfully promoted vascularized bone regeneration in animal models. These advancements establish a solid foundation for stem cell-biomaterial synergy in functional tissue regeneration.

Vital Pulp Preservation

Our primary study developed an amorphous calcium phosphate/poly (L-lactic acid)-poly (lactic-co-glycolic acid) membrane compounded with aspirin. The composite membrane, used as a pulp-capping material, allowed for the sequential release of the anti-in ammatory drug aspirin as well as the calcium/phosphorus ions required for mineralization. It had the dual effects of reducing inflammation and promoting mineralized barrier formation. The composite membrane represents a promising vital pulp conservation material with the potential for clinical applications.

Tooth Development

The study of tooth development regulation provides a critical opportunity to explore how tissue-tissue interactions govern organogenesis, while also offering insights into tooth regeneration. Leveraging single-cell RNA sequencing, we have constructed comprehensive atlases of human and mouse dental pulp cells across multiple spatial and temporal levels, uncovering distinct cellular subpopulations and their interactive networks. Through mutant models and in vitro experiments, we have elucidated the roles of Runx2, Notum, Mia and Wnt signaling pathway in tooth development and demonstrated their potential applications in pulp and dental regeneration. These findings advance our understanding of key signaling molecules in odontogenesis and pave the way for innovations in dentin biology and regenerative dentistry.
