Data supporting that miR-92a suppresses angiogenic activity of adipose-derived mesenchymal stromal cells by down-regulating hepatocyte growth factor.

ABSTRACT: This article contains the full list of miRNAs expressed in cultured mesenchymal stromal cells, which were isolated from human adipose tissue. We provide here data regarding the effect of miR-92a overexpression on MSCs viability and cellular content of HGF and angiopoietin-1. These are followed by the data regarding the effect of conditioned medium of MSC transfected with pre-miR-92a, anti-miR-92a or scramble oligos on HUVEC viability as well as their tube formation efficiency. We also demonstrate here data regarding the effect of extracellular vesicle depletion from MSCs conditioned medium on its ability to stimulate the tube formation by HUVEC. Data interpretation and discussion can be found in Kalinina et al. (2015) [1].

Project description:ObjectiveRecent advances in cell therapy have encouraged researchers to provide an alternative for treatment and restoration of damaged liver through using hepatocytes. However, these cells quickly lose their functional capabilities in vitro. Here, we aim to use the secretome of mesenchymal stromal cells (MSCs) to improve in vitro maintenance conditions for hepatocytes.Materials and methodsIn this experimental study, following serum deprivation, human adipose tissue-derived MSCs (hAT-MSCs) were cultured for 24 hours under normoxic (N) and hypoxic (H) conditions. Their conditioned media (CM) were subsequently collected and labeled as N-CM (normoxia) and H-CM (hypoxia). Murine hepatocytes were isolated by perfusion of mouse liver with collagenase, and were cultured in hepatocyte basal (William's) medium supplemented with 4% N-CM or H-CM. Untreated William's and hepatocyte-specific media (HepZYM) were used as controls. Finally, we evaluated the survival and proliferation rates, as well as functionality and hepatocyte-specific gene expressions of the cells.ResultsWe observed a significant increase in viability of hepatocytes in the presence of N-CM and H-CM compared to HepZYM on day 5, as indicated by MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)- 2H-tetrazolium) assay. Indocyanine green (ICG) uptake of hepatocytes in the H-CM and HepZYM groups on days 3 and 5 also suggested that H-CM maintained the hepatocytes at about the same level as the hepatocyte-specific medium. The HepZYM group had significantly higher levels of albumin (Alb) and urea secretion compared to the other groups (P<0.0001). However, there were no significant differences in cytochrome activity and cytochrome gene expression profiles among these groups. Finally, we found a slightly, but not significantly higher concentration of vascular endothelial growth factor (VEGF) in the H-CM group compared to the N-CM group (P=0.063).ConclusionThe enrichment of William's basal medium with 4% hAT-MSC-H-CM improved some physiologic parameters in a primary hepatocyte culture.
