Fig. 4. SCs-derived cells and Ca_v1.2 participate in the regeneration of incisors after injury. (A-C) represent the expression of GFP^＋ cells (green) and Ca_v1.2 (red) at the dental cusp, middle teeth and apical area of control and injured incisors with recovery for 0, 12, 48, 72 hours, 5 days, and 1 week, respectively. Boxed areas are shown magnified in (D) correspondingly. (D) The possible route of SCs-derived cells migrating to the odontoblast layer. The asterisk highlights GFP^＋ cells. (E) Co-expression of GFP^＋ cells and Ca_v1.2. Boxed areas are shown magnified to the right. Scale bar=50 μm. d: dentin, p: dental pulp, CL: cervical loop.
