Fig. 6From: Human platelet lysate in mesenchymal stromal cell expansion according to a GMP grade protocol: a cell factory experienceMSC relative telomere length at passage 4. Data presented as mean ± SD with n = 12. RTL value calculated as ratio between telomere signal of each sample and control cells (K562 line) with correction for DNA index of G0–G1 cells. No significant differences observed (p > 0.05). FBS fetal bovine serum, NS not significant, PL platelet lysateBack to article page
