Correlation of TCF4, GSK, TERT and TERC Expressions with
Proliferation Potential of Early and Late Culture of Human
Peripheral Blood Mesenchymal Stem Cells
In the recent years, mesenchymal stem cells (MSCs) were considered as the suitable source of cells for transplantation into the damaged tissues in regenerative medicine. There was low number of these cells in different organs and this characteristic was the main drawback to use them in treatment of diseases. Cellular senescence of the stem cells has been demonstrated to be dependent to the telomerase activity. The aim of present experimental study was to evaluate correlation of the expression of telomerase components and WNT signaling pathway in MSCs derived from human peripheral blood (PB-MSCs).
Materials and Methods
In this experimental study, following the isolation of MSCs from peripheral blood mononuclear
cells, RNA was extracted from these cells in the early culture (8-9th days) and late culture (14-17th days). Then, expression
Our data indicated that there was a significantly reduced expression of
The obtained results suggested that WNT signaling pathway likely plays a minor role in the maintenance of telomere length and proliferation potential of MSCs.
