| Summary: | Objective: 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
of TERT, TERC, TCF4, GSK and CTNNB1 was determined by quantitative reverse transcription polymerase chain
reaction (qRT-PCR) based on SYBR Green.
Results: Our data indicated that there was a significantly reduced expression of TERT in the late culture of human
MSCs derived from peripheral blood (P<0.05). Although a negative correlation was observed between GSK and TERC
expression levels in the early culture of MSCs, spearman analysis showed that there was no significant correlation
between the expression of telomerase components (TERC and TERT) and WNT signaling pathway (P>0.05).
Conclusion: The obtained results suggested that WNT signaling pathway likely plays a minor role in the maintenance
of telomere length and proliferation potential of MSCs. |
