Background: Our previous studies have shown that Pygo (Pygopus) in Drosophila plays a critical role in adult heart function that is likely conserved in mammals. However, its role in the differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) into cardiomyocytes remains unknown. Objective: To investigate the role of pygo2 in the differentiation of hUC-MSCs into cardiomyocytes. Methods: Third passage hUC-MSCs were divided into two groups: a p+ group infected with the GV492-pygo2 virus and a p− group infected with the GV492 virus. After infection and 3 or 21 days of incubation, Quantitative real-time PCR (qRT-PCR) was performed to detect pluripotency markers, including OCT-4 and SOX2. Nkx2.5, Gata-4 and cTnT were detected by immunofluorescence at 7, 14 and 21 days post-infection, respectively. Expression of cardiac-related genes—including Nkx2.5, Gata-4, TNNT2, MEF2c, ISL-1, FOXH1, KDR, αMHC and α-Actin—were analyzed by qRT-PCR following transfection with the virus at one, two and three weeks. Results : After three days of incubation, there were no significant changes in the expression of the pluripotency stem cell markers OCT-4 and SOX2 in the p+ group hUC-MSCs relative to controls (OCT-4: 1.03 ± 0.096 VS 1, P > 0.05, SOX2: 1.071 ± 0.189 VS 1, P > 0.05); however, after 21 days, significant decreases were observed (OCT-4: 0.164 ± 0.098 VS 1, P < 0.01, SOX2: 0.209 ± 0.109 VS 1, P < 0.001). Seven days following incubation, expression of mesoderm specialisation markers, such as Nkx2.5, Gata-4, MEF2c and KDR, were increased; at 14 days following incubation, expression of cardiac genes, such as Nkx2.5, Gata-4, TNNT2, MEF2c, ISL-1, FOXH1, KDR, αMHC and α-Actin, were significantly upregulated in the p+ group relative to the p− group (P < 0.05). Taken together, these findings suggest that overexpression of pygo2 results in more hUCMSCs gradually differentiating into cardiomyocyte-like cells. Conclusion: We are the first to show that overexpression of pygo2 significantly enhances the expression of cardiac-genic genes, including Nkx2.5 and Gata-4, and promotes the differentiation of hUC-MSCs into cardiomyocyte-like cells.

: Mesenchymal stem cells because of its high proliferation, differentiation, regenerative capacity, and ease of availability have been a popular choice in cytotherapy. Mesenchymal Stem Cells (MSCs) have a natural tendency to home in a tumor microenvironment and acts against it, owing to the similarity of the latter to an injured tissue environment. Several studies have confirmed the recruitment of MSCs by tumor through various cytokine signaling that brings about phenotypic changes to cancer cells, thereby promoting migration, invasion, and adhesion of cancer cells. The contrasting results on MSCs as a tool for cancer cytotherapy may be due to the complex cell to cell interaction in the tumor microenvironment, which involves various cell types such as cancer cells, immune cells, endothelial cells, and cancer stem cells. Cell to cell communication can be simple or complex and it is transmitted through various cytokines among multiple cell phenotypes, mechano-elasticity of the extra-cellular matrix surrounding the cancer cells, and hypoxic environments. In this article, the role of the extra-cellular matrix proteins and soluble mediators that acts as communicators between mesenchymal stem cells and cancer cells has been reviewed specifically for breast cancer, as it is the leading member of cancer malignancies. The comprehensive information may be beneficial in finding a new combinatorial cytotherapeutic strategy using MSCs by exploiting the cross-talk between mesenchymal stem cells and cancer cells for treating breast cancer.
