摘要

In this work it was found that the expression level of 144 genes significantly changed in human mesenchymal stem cells during their osteogenic differentiation after 20 days of exposure to simulated microgravity: the expression of 30 genes significantly increased (from 1.7 to 11.9 fold), and 114 – decreased (from 0.2 to 0.6 fold). Most of the revealed genes were attributed to the 11 major groups corresponding to its biological role in the cells. Additional group was formed from the genes which did not belong to these categories, or did not have a description in the known databases (such as Pubmed). The greatest number of genes with altered expression was found in the group “Matrix and Adhesion", while the lowest – in the "Apoptosis and the response to external stimuli" group. These findings suggest that cultured hMSCs, placed in non-standard conditions, maintain a high level of viability, but have significantly altered functional properties which could affect their efficiency to differentiate towards osteogenic direction.
