Expression of CD146 and Regenerative Cytokines by Human Placenta-Derived Mesenchymal Stromal Cells upon Expansion in Different GMP-Compliant Media

Figure 4

Effect of PLL on proliferation of pMSCs. The pMSCs from 5 donors were expanded either in LM, medium complemented by serum, serum+PLL, or plasma+PLL and further cultured for 2 consecutive passages in medium enriched (grey bars) with or deprived from PLL (black bars) as indicated. Addition of PLL to expansion media increased cell proliferation in both cases (left side), while PLL deprivation reduced proliferation in the other two cases (right side).
