| Adipose tissue is one of the tissues used to generate mesenchymal stem cells (MSCs) and has advantages such as easy
access, minimal invasiveness, as well as the possibility of harvesting a large number of cells from it. This study was
conducted mainly to evaluate the growth, proliferation, and adhesion of cells to the scaffold, as well as to evaluate
and compare changes in the expression of IL-1Ra, IL-10, and TNF-α genes in three conditions of culture medium,
control sample, scaffold containing alendronate (Aln), and scaffold without the drug. To access adipose-derived
stem cells, adipose tissue was prepared and the cells were cultured in the culture medium and scaffolds after
isolation. Their growth and proliferation rates were then assessed by MTT assay. Moreover, an appropriate dose of
non-toxic Aln was reported. Finally, the expression of the above genes was measured by Realtime-PCR under the
three conditions mentioned, and the obtained data were analyzed. All these steps were tested in 24-hour and 5-day
intervals. The results indicated that the growth and proliferation of cells in the scaffold containing Aln was
significantly increased compared to the empty culture medium. And the expression of the pro-inflammatory gene
(TNF-α) decreased in scaffolds containing Aln drug (which has an anti-inflammatory effect) compared to scaffolds
without the drug. On the other hand, the expression level of anti-inflammatory genes (IL-10 and IL-1Ra) increased
in scaffolds containing drugs significantly compared to scaffolds without drugs. |
