Research Interests

Dr. Feng performs research in craniofacial, tooth and bone developmantal biology, with a particular interest in understanding the roles of Dentin matrix protein-1, Bmp receptor 1A, beta-catenin, periostin and mechanical loading during development.  In addition, Dr. Feng is interested in understanding tooth root formation using a naturally occurring osteoporosis mouse model.  He is also interested in understanding the mechanism by which Pax-9 in mutation in exon 3 leads to tooth agenesis.

Dr. Feng's contributions to science include the following:

1)  Discoveries of genes that control cell fates, morphogenesis and growth at condyle and growth plate
There has been substantial progress in understanding the embryonic formation of the limb growth plate since the molecular biology era began.   In search for the molecular mechanisms that control postnatal chondrogenesis, we discovered specific genes (Bmpr1a and Osx) that are vital for the regulation of postnatal growth of the mandibular condylar and growth plate.  We proved that the vast majority of subchondral bone cells in either condylar or growth plate or  articular cartilage directly originate from chondrocytes.       Figure:  We believe that some chondrocytes directly transform to endothelial cells .              

2) Identification of a novel Nfic-Osx-Dspp signaling pathway in tooth root formation
Although tooth consists of crown and root, most research focuses on crown dentin formation with less attention on postnatal tooth formation studies.  As a result, attempts to regenerate a complete tooth have not been successful, partly due to the lack of appropriate animal models, plus the inherant difficulties associated with handling mineralized root dentin within the bone socket.  To search for the factors critical for tooth root formation, we demonstrated that 1) Osx (the gene vital for skeletal formation but still unknown as to its function in tooth dentin formation is specifically required for root dentin but not for crown dentin formation; 2) OSX is the key downstream molecule of NFIC (a master transcriptional factor essential for root but not for dentin formation; and 3) DSPP, a critical matrix protein in dentin is directly regulated by the Nfic-Osx signaling pathway.  This work points to a mechanism of tooth crown formation that differs from the mechanism of tooth crown formation (see above).

3) Establishment of the novel role of periodontium in normal health and diseases
Understanding periodontium biology and developing an effective treatment for bone and PDL damage due to periodontitis (one of the most common human diseases) has been a longstanding aim in dentistry and medicine.  Our key findings in our studies were 1) PDL progenitor cells (cells differentiating into a specific type of cell) serve as the major initiators for alveolar bone formation; 2) It was proven in this study that the pathological changes in osteocytes are the key pathological factors responsible for bone loss and PDL damage in two severe human periodontitis cases and the periodontitis-engineered animal model.  It was demonstrated that deleting the Sost gene (a potent inhibitor of WNT-ß-catenin signaling) or blocking sclerostin function using the monoclonal antibody in this periodontitis model prevents and repairs bone and PDL defects.

4) Discoveries of osteocyte role in bone mineralization and remodeling
For more than a century, osteoblasts have been viewed as the cells responsible for bone formation, while osteocytes (the cells that are buried in mineralized tissue, are treated as the "retired bond buildinges" with limited functions such as "mechanosensors".  Dr. Feng's recent findings have shown that it is the osteocyte that forms mineralized bone and defects in this cell are responsible for osteomalacia in children and osteoporosis in older people.  The current theory is that new bone is produced by osteoblasts from the bone surface
