Stemness Characteristics of Periodontal Ligament Stem Cells from Donors and Multiple Sclerosis Patients: A Comparative Study

Figure 2

Cell proliferation and viability abilities. Cell proliferation and viability of P2 and P15 hPDLSCs at different time points were evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium-bromide (MTT) assay and trypan blue exclusion test. Histograms show MTT assay and trypan blue assay data in P12 and P15 of normal hPDLSCs ((a) and (c), resp.) and MS-hPDLSCs ((b) and (d), resp.).Values are expressed as mean ± S.D. ^δStatistically significanct differences for each time for cells at P2. ^#Statistically significant differences for each time for cells at P15.
