Stem Cells and Tissue Engeineering

Tissue engineering seeks to generate new tissues or regenerate lost tissues through a combination of stem cells, materials design, and biochemical and molecular cues.  The first step toward tissue engineering in our lab began with a focus on periodontal stem cells in 2001, for which we were awarded an NIH grant (DE15425) in 2003.  At that point we began to generate and characterize stem cell populations in developing periodontal tissues (Luan et al. 2006, 2009, Dangaria et al. 2009, 2011a, Gopinathan et al. 2013).  Subsequently, we have established periodontal progenitor populations to regenerate the periodontium of extracted teeth and replant these teeth into sockets (Dangaria et al. 2011b,c).

This research has prompted a number of studies related to the design of scaffolds and homing factors for odontogenic regeneration (Li et al. 2013, Pan et al. 2013, Huang et al. 2013). Over time, we have expanded our repertoire of molecular cues (Francis et al. 2020, Pandya et al. 2021, Ma et al. 2021, Lyu et al. 2022) to include histone demethylases, neuropeptides and hormones.  In parallel, we have continuously expanded on our portfolio of innovative and complex materials, focusing on electrospinning and multi-layer coating to achieve histocompatibility, degradability and optimum release characteristics (Qian et al. 2019, Lyu et al. 2022).  We aim that our strategies will improve the healing and new formation of complex tissues.
