摘要
Objective: Myogenic satellite cells were isolated from semitendinosus muscle of prepubertal Korean black goat to observe the differential effect of linolenic and retinoic acid in thepresence of thiazolidinediones (TZD) and also to observe the production insulin sensitive preadipocyte.
Methods: Cells were characterized for their stemness with cluster of differentiation 34 (CD34), CD13, CD106, CD44, Vimentin surface markers using flow cytometry. Cells characterized themselves as possessing significant (p<0.05) levels of CD13, CD34, CD106, Vimentin revealing their stemness potential. Goat myogenic satellite cells also exhibited CD44, indicating that they possessed a % of stemness factors of adipose lineage apart from their inherent stemness of paxillin factors 3/7.
Results: Cells during proliferation stayed absolutely and firmly within the myogenic fate without any external cues and continued to show a significant (p< 0.05) fusion index % to express myogenic differentiation, myosin heavy chain, and smooth muscle actin in 2% horse serum. However, confluent myogenic satellite cells were the ones easily turning into adipogenic lineage. Intriguingly, upregulation in adipose specific genetic markers such as peroxisome proliferation-activated receptor gamma, adiponectin, lipoprotein lipase, and CCAAT/enhancer binding protein a were observed and confirmed in all given treatments. However, the amount of adipogenesis was found to be statistically significant (p<0.01) with linolenic acid as compared to retinoic acid in combination with TZD's.
Conclusion: Retinoic acid was found to produce smaller preadipocytes which have been assumed to have insulin sensitization and hence retinoic acid could be used as a potential agent to sensitize tissues to insulin in combination with TZD's to treat diabetic conditions in humans and animals in future.
