Abstract

The role of miR-16/15b/195 and complementary compounds in the commitment of mesenchymal stem cells (MSCs) to different lineages is unknown. The aim of this work was to investigate the effect of ketorolac and triamcinolone acetonide on adipogenic and hepatogenic processes, respectively. Also, miR-16/15 and miR-195 expression levels were evaluated under different induction conditions. MSCs were isolated, expanded and directed using adipogenesis medium or medium supplemented with ketorolac, and also subjected to hepatogenic differentiation using a cocktail of hepatocyte growth factor (HGF) and Oncostatin M (OSM) either with or without triamcinolone acetonide. Periodic acid-Schiff (PAS) staining, Oil red O staining, albumin and adiponectin protein secretion were evaluated. MiR-16 family expression level was assessed using qRT-PCR in four induced groups as compared to non-induced cells. The expression levels of miR-16 and miR-15 increased significantly from adipose derived stem cells to adipocytes (p<0.01). Positive stimulatory effects of ketorolac and triamcinolone on adipogenic and hepatogenic induction, respectively, were observed. Ketorolac stimulated upregulation of miR-16/15b in the adipogenic induced stem cells. Interestingly...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
