概要 Cell differentiation is controlled by specific transcriptionfactors. The functions and expression levels of these transcription factors are regulated by epigenetic modifications, such as histone modifications and cytosine methylation of the genome. In tendon tissue, tendon-specific transcription factors have been shown to play functional roles in the regulation of tenocyte differentiation. However, the effects of epigenetic modifications on gene expression and differentiation in tenocytes are unclear. In this study, we investigated the epigenetic regulation of tenocyte differentiation, focusing on the enzymes mediating histone 3 lysine 9 (H3K9) methylation. In primary mouse tenocytes, six H3K9 methyltransferase (H3K9MTase) genes, i.e., G9a, G9a-like protein (GLP), PR domain zinc finger protein 2 (PRDM2), SUV39H1, SUV39H2, and SETDB1/ESET were all expressed, with increased mRNA levels observed during tenocyte differentiation. In mouse embryos, G9a and Prdm2 mRNAs were expressed in tenocyte precursor cells, which were overlapped with or were adjacent to cells expressing a tenocyte-specific marker, tenomodulin. Using tenocytes isolated from G9a-flox/flox mice, we deleted G9a by infec
