摘要

In this work it was found that the expression level ofrn144 genes significantly changed in human mesenchymalrnstem cells during their osteogenic differentiation afterrn20 days of exposure to simulated microgravity: thernexpression of 30 genes significantly increased (from 1.7rnto 11.9 fold), and 114 – decreased (from 0.2 to 0.6 fold).rnMost of the revealed genes were attributed to the 11rnmajor groups corresponding to its biological role in therncells. Additional group was formed from the genesrnwhich did not belong to these categories, or did not haverna description in the known databases (such as Pubmed).rnThe greatest number of genes with altered expressionrnwas found in the group “Matrix and Adhesion", whilernthe lowest – in the "Apoptosis and the response tornexternal stimuli" group. These findings suggest thatrncultured hMSCs, placed in non-standard conditions,rnmaintain a high level of viability, but have significantlyrnaltered functional properties which could affect theirrnefficiency to differentiate towards osteogenic direction.
