The cells featured in the study by Ostrow School of Dentistry of USC were 'gingival mesenchymal' stem cells (GMSC), which are found in the gingiva, or gum tissue, within the mouth.

# K$ O* @/ s& fThe study shows that there are two types of GMSC: those that arise from the mesoderm layer of cells during embryonic development (M-GMSC) and those that come from cranial neural crest cells (N-GMSC).7 h/ i( ^1 c' G1 X

The cranial neural crest cells develop into many important structures of the head and face, and 90 percent of the gingival stem cells were found to be N-GMSC.$ e5 H6 V1 G( k" p, G; }, e5 {
