CD90+ adipose-derived mesenchymal stem cells in an alveolar extraction socket model
Seth R. Brooks obtained his DDS from the University of Oklahoma College of Dentistry in 2014. Following graduation he completed a 1 year fellowship in Dental Anesthesia at the Indiana University School of Medicine prior to starting his residency in Oral and Maxillofacial Surgery at the University of Tennessee Medical Center in Knoxville.
The proposed study aims to evaluate the use of adult adipose-derived mesenchymal stem cells in bony tissue regeneration of extraction sockets in rats. Due to time, economical and restorative concerns associated with implant placement after dental extractions, bone regenerative therapies have garnered much attention in recent years. Current treatments, based on autologous and allogenic bone grafts, suffer from inherent challenges and hence, the ideal bone replacement therapy is yet to be found. In this proposal, a team of clinicians and researchers at UTMCK along with colleagues at UTCVM will test, in vitro, three scaffolds and determine which is the most biocompatible with adult mesenchymal stem cells. Subsequently we will test the in vivo efficiency of these scaffolds seeded with adult mesenchymal stem cells in a rat model of extraction socket defect. The long term goal is to translate this rat model to a large animal and ultimately make this strategy available to human medicine.
