Özet

Mesenchymal stem cells (MSCs) from a variety of sources are being used in pre-clinical and clinical studies. The choice of optimal source for treatment of diseases requires quantitative evaluation of self-renewal, proliferation and differentiation potencies of MSCs. For this purpose, quantitative real-time polymerase chain reaction (qRT-PCR) technique is used to determine the expression of genes. qRT-PCR requires the normalization of the gene expression levels by the use of reference genes in order to obtain accurate and reliable results. There is a limited number of studies focused on the selection of reference genes that are appropriate and reliable for MSCs. Thus, no single reference gene has yet been found for use in the in vitro proliferation and differentiation of MSCs. The aim of this study is to investigate the stability of the expression of widely used reference genes during the in vitro proliferation and differentiation of human adipose-derived mesenchymal stem cells (hASCs). For this purpose, 13 reference genes commonly used in MSC studies were selected. As a result, the expression stabilities of EF1 alpha, RPLP0 and RPL13A genes were found to be high and were predicted to be suitable for use as reference genes for normalization in hASC studies. The GAPDH was identified as the gene with the lowest expression stability and evaluated to be an unsuitable reference gene for hASC differentiation studies. This piece of information could be crucial for the selection of appropriate reference genes and accurate measurement of gene expression in hASC studies.
