From: Effect of cryopreservation on proliferation and differentiation of periodontal ligament stem cell sheets

Fig. 2

The cryopreserved periodontal ligament stem cell (cPDLSC; a) and freshly prepared periodontal ligament stem cell (fPDLSC; b) sheets had similar cell viability rates as indicated by the EdU-based cell viability assay. Examples of live and dead cells are indicated in green and red, respectively (solid triangles: live cells; arrows: dead cells). c Different cell viability rates of fPDLSC sheets (97.5%) and cPDLSC sheets (97.3%). P = 0.7425. Scale bars = 40 μm. Magnification: 20×
