Transcriptomics analysis of proliferation and differentiation of buffalo muscle stem cells

Buffalo breeding has become an important branch of beef cattle industry. It is of great significance to study buffalo meat production and meat quality. However, the important role of mRNA and lncRNA molecules in muscle stem cells (MuSCs) development in buffalo has not been explored. Then, we performed mRNA and lncRNA expression profiling analysis on the proliferation and differentiation of MuSCs in buffalo. The results showed that there were 4,820 differentially genes, 12,227 mRNAs, and 1,352 lncRNAs. These differentially expressed mRNAs are enriched in biological processes such as cell cycle, p53 signaling pathway, RNA transport, and Calcium signaling pathway and others. We also identified a number of genes, such as MCMC4, SERDINE1, ISLR, LOC102394806, and LOC102403551, and found that interference with MYLPF expression significantly inhibited the differentiation of MuSCs. In conclusion, our research revealed the role of mRNA and lncRNA expression in the differentiation of buffalo MuSCs. This study can be used as an important reference for the study of RNA regulation during muscle development in buffalo.
