Differentiation Potential of Human Wharton’s Jelly-Derived Mesenchymal Stem Cells and Paracrine Signaling Interaction Contribute to Improve the In Vitro Maturation of Mouse Cumulus Oocyte Complexes

qPCR analysis of OCT4 in hWJ-MSCs cultured under the 4 coculture conditions. In G1-PLUS, TYH, and G2-PLUS, OCT4 expression was downregulated to 25.9, 24.7, and 6.6%, respectively, compared to the OCT4 level in hWJ-MSCs cultured in DMEM-F12. The expression of OCT4 from hWJ-MSCs was not affected by the presence of COCs when cultured in DMEM-F12 (control group). The data was analyzed with the two-tailed paired Student’s t-test. A value < 0.05 was considered to indicate statistical significance. () is the statistical significance compared with coculture-DMEM-F12.
