Adipogenesis is a complex multi-step process involving the differentiation of preadipocytes into mature adipocytes. Myostatin, a member of the transforming growth factor beta superfamily, is mainly expressed in skeletal muscle and has been shown to inhibit both myogenesis and adipogenesis. Arg, an important amino acid, is known for its positive effects on energy metabolism and muscle growth. In this study, we aim to investigate the regulatory roles of Myostatin and Arg in the adipogenic differentiation of porcine mesenchymal stem cells (pMSCs).Methods:- Isolation and culture of pMSCs from pig bone marrow.- Characterization of pMSCs by flow cytometry.- Treatment of pMSCs with Myostatin and Arg for adipogenic differentiation.- Verification of adipogenic differentiation by Oil Red O staining, qRT-PCR analysis of adipogenic marker genes, and Western blot analysis of adipogenic proteins.- Data analysis using statistical software.Expected results:We expect that Myostatin treatment will reduce adipogenic differentiation of pMSCs while Arg treatment will enhance it. This will be confirmed by increased expression of adipogenic markers such as PPARγ and adiponectin, as well as increased protein levels of adipogenic markers such as FABP4 and perilipin in the Arg-treated group. The Myostatin-treated group is expected to have decreased expression and protein levels of these markers.Significance:The results of this study will provide valuable insights into the regulation of adipogenesis in pigs and may have important 精品文档---下载后可任意编辑implications for improving pig production and meat quality. It may find application in breeding programs aimed at improving the health and economics of the swine industry. Furthermore, it may also contribute to the understanding of human obesity and metabolic disorders, as pigs are considered valuable animal models for human physiology and disease.
