Stem cells hold great promise for regenerative medicine and the treatment of cardiovascular diseases. The mechanisms regulating self-renewal, pluripotency, and differentiation are not fully understood. MicroRNAs (miRs) are small noncoding RNAs controlling gene expression, either by inducing mRNA degradation or by blocking mRNA translation. The expression of miRs was shown to regulate various as...

background: mesenchymal stem cells (mscs) are important candidates for msc-based cellular therapy. current paradigm states that mscs support local progenitor cells in damaged tissue through paracrine signaling. therefore, study of paracrine effects and secretome of mscs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. this study ...

The potential for the clinical application of stem cells in tissue regeneration is clearly significant. However, this potential has remained largely unrealized owing to the persistent challenges in reproducibly, with tight quality criteria, and expanding and controlling the fate of stem cells in vitro and in vivo. Tissue engineering approaches that rely on reformatting traditional Food and Drug...

objective(s):mesenchymal stem cells (mscs) derived from wharton’s jelly (wj-mscs) are now much more appealing for cell-based infertility therapy. hence, wj-mscs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. materials and methods: mscs were isolated from human wharton’s jelly and treated with bmp4, retinoic acid (ra) or co-cultured on human...
