Figure 5. After 72 hours of PDLSCs culture in four different media, the Ca2+ levels of each group were detected by confocal microscopy (A), and the mitochondrial membrane potential (JC-1) changes of each group were analyzed by flow cytometry (B). Data are presented as the mean ±standard deviation (SD) (n=3). (ns P>0.05, * P<0.05, ** P<0.01, *** P<0.001).
