Abstract: Umbilical cord and cord blood are acceptable as attractive sources of mesenchymal and hematopoietic stem cells, since their collection is non-invasive, painless, and does not evoke the ethical concerns. Microorganism-stem cell interaction plays an important role in stem cell self-renewal, differentiation, secretion profile and death. In the literature, few researchers are examining the relationship between pathogenic and commensal bacteria with umbilical cord-derived Mesenchymal Stem Cells (MSCs). These relationships vary depending on the bacterial load and the presence of the immune cell in the environment. Several bacterial pathogens act in the regenerative capacity of MSCs by changing their phenotype, development and viability due to several stress factors that are created by a microorganism such as hypoxia, oxidative stress, etc. On the other hand, the anti-inflammatory and antibacterial effects of MSCs were shown and these phenomena increased when the number of bacteria was high but decreased in the presence of low amounts of bacteria. The antibacterial effects of MSCs increased in the early period of infection, while their effects were decreased in the late period with high inflammatory response and bacterial load. In this review, we discussed the microbial stresses on human umbilical cord stem cells.
