Abstract
Although previous studies have reported the effects of extensive subculturing on proliferation rates and osteogenic potential of human mesenchymal stem cells (hMSCs), the results remain controversial. The aim of our study was to characterize the proliferation and osteogenic potential of hMSCs during serial subculture, and also to identify proteins that are differentially regulated in hMSCs during serial subculture and osteogenic differentiation using proteome analysis. Here we show that the proliferation and osteogenic capacity of hMSCs decrease during serial subculturing. Several proteins were shown to be differentially regulated during serial subculture; among these the expression of T-complex protein 1 α subunit (TCP-1α), a protein known to be associated with cell proliferation, cell cycle, morphological changes, and apoptosis, gradually decreased during serial subculture. Among proteins that were differentially regulated during osteogenic differentiation, chloride intracellular channel 1 (CLIC1) was downregulated only during the early passages eukaryotic translation elongation factor, and acidic ribosomal phosphoprotein P0 was downregulated during the middle passages, while annexin V, LIM, and SH3 domain protein 1 (LASP-1), and 14-3-3 protein gamma (YWHAG) were upregulated during the later passage. These studies suggest that differentially regulated passage-specific proteins may play a role in the decrease of osteogenic differentiation potential under serial subculturing.
