Increased CD90/Thy1 expression is localized to the incisor MSC region after clipping. a, b Immunofluorescent staining of CD90/Thy1 identifies expression localized to the region in dental pulp between the epithelial cervical loop and no expression is detected in the TAC region 2 days after clipping. c Quantification of CD90/Thy1 expression in clipped incisors compared to unclipped incisors (N > = 3 per group, 10 week adult mice). d, e FACS analysis of CD90/Thy1 cre; mTmG mice shows a three fold increase in GFP + cells from clipped incisors compared to unclipped. f Quantification of GFP + cells in the pulp cells and odontoblasts on sagittal sections. N > = 5 mice per group. *P < 0.05, **P < 0.01 and ***P < 0.001 by Student’s t-test. Data presented as mean ± S.E.M
