Microvesicles from Human Immortalized Cell Lines of Endothelial Progenitor Cells and Mesenchymal Stem/Stromal Cells of Adipose Tissue Origin as Carriers of Bioactive Factors Facilitating Angiogenesis

Figure 8

Cell proliferation evaluated with the standard MTT test. Human dermal endothelial cells HSkMEC.2, human fibroblast cell line MSU-1.1, and human keratinocyte cell line HaCaT were cultured in the presence of microvesicles (MVs) isolated from HEPC-CB.1 (a) or adipose tissue immortalized cell line HATMSC1 (b). Proliferation was assessed on days 3, 5, and 7 of culture. Results represent , (, , and calculated vs. control for a defined time point; ^#, ^##, and ^### calculated at a given day vs. day 0 for each treatment).
