Mesenchymal stem cells are a tool in cell therapies but demand a large cell number per treatment, for that, suitable culture media is required which contains fetal bovine serum (FBS). However, for cell-based therapy applications, the use of FBS is problematic. Several alternatives to FBS have been explored, including human derivatives from platelet-rich plasma (hD-PRP). Although various studies have evaluated the impact of hD-PRP on MSC proliferation and differentiation, few of them have assessed their influence on processes, such as metabolism and gene expression. Here, we cultured human adipose-derived MSCs (hAD-MSCs) in media supplemented with either 10% hD-PRP (hD-PRP-SM) or 10% FBS (FBS-SM) in order to characterize them and evaluate the effect of hD-PRP on cell metabolism, gene expression of associated regenerative factors, as well as chromosome stability during cell expansion. We found that hAD-MSCs cultured in hD-PRP-SM have a greater cell elongation but express similar surface markers; in addition, hD-PRP-SM promoted a significant osteogenic differentiation in the absence of differentiation medium and increased the growth rate, maintaining chromosomal stability. In terms of cell metabolic profile, hAD-MSC behavior did not reveal any differences between both culture conditions. Conversely, significant differences in collagen I and angiopoietin 2 expression were observed between both conditions. The present results suggest that hD-PRP may influence hAD-MSC behavior.
