Model of transfection in human endometrial epithelium cells with hsa-miR-191-5p Model of transfection in human endometrial epithelium cells with hsa-miR-191-5p

Background: Human endometrial cells are important in blastocyst recognition and implantation. We have recently shown that miR-191-5p secreted into culture medium by human embryos cultured and transferred to woman on the fifth day of development was associated with the percentage of pregnant vs. non-pregnant patients. Little is known about the regulation and expression of endometrial miRNAs induced by embryonic miRNAs in endometrial tissue. Therefore, in the present work we explored the viability and transfection of RL95-2 endometrial cell line with agomiR-191. Results: The main results obtained in this study were: First, transfection of RL95-2 cell line with 100nM of lipofectamine in combination with 15, 30, and 60 nM of agomiR-191 for 3, 6 and 24 hours does not affect the viability of RL95-2 cells. Second, we observed expression of miR-191 with 60 pmol of agomiR-191 in a time dependent transfection. Conclusion:: Stimulation of RL95-2 endometrial cell line with lipofectamine does not modify their viability. The transfected RL95-2 endometrial cells showed increased the expression of miR-191.
