Expression of senescence-associated genes in multipotent mesenchymal stromal cells during long-term cultivation at various hypoxic levels

详细

The expression of several genes which functions are associated with cellular senescence was analyzed in multipotent mesenchymal stromal cells during long-term cultivation at different oxygen levels (20, 5, and 1%) using the RT² Profiler™ PCR Array Human Cellular Senescence system (Qiagen, United States). It was established that replicative senescence processes develop most actively in the cells cultured under the standard conditions (20% O₂). The most significant changes were observed in the expression of CCND1, ID1, IGF1, PIK3CA, and SERPINE1 genes.
