Abstract
The conditioned medium (CM) could be used as the suitable source of growth factors in the regenerative medicine which had the ability to enhance efficiency of stem cells in the repair of injured tissues. In the present study, we studied the effect of conditioned medium derived from HEK293 (HEK293-CM) on the expression of CD2AP, CDH16, and WT1 genes in the human adipose-mesenchymal stem cells (AD-MSCs). For this purpose, the human AD-MSCs were treated with different concentrations (5%, 10%, or 15%) of prepared HEK293-CM. Then, the expression level of three renal markers, CD2AP, CDH16, and WT1, was determined in the treated cells as compared with untreated cells as the control group. Our data showed that treatment with 15%CM-5%FBS-24 h and 5%CM-10%FBS-72 h was significantly associated with enhanced expression of CD2AP and WT1 in AD-MSCs (p < 0.05). Furthermore, increased expression of CDH16 and CD2AP was observed in AD-MSCs treated by 10%CM-1%FBS-48 h (p = 0.0002 and p = 0.02 for CDH16 and CD2AP, respectively). The results obtained from this study indicated that HEK293-CM had the ability to increase the characteristics related to the renal cell lineage in AD-MSCs. This approach could be introduced as the novel method to enhance the ability of stem cells in the repair of renal injuries.
Lay Summary
Different studies showed that the conditioned medium provided the novel approach to enhance the stem cells efficiency in the repair of the injured tissues. The growth factors secreted from the cells into the medium could be used as the alternative option to stimulate the differentiation ability of stem cell. In the present study, we prepared the conditioned medium from HEK293 (HEK293-CM) and evaluated its effect on the adipose-mesenchymal stem cells (AD-MSCs).The obtained results indicated that HEK293-CM had the ability to increase the characteristics related to the renal cell lineage in AD-MSCs.
