Human umbilical cord blood (UCB)-derived multipotent stem cells are regarded as valuable sources for cell transplantation and cell therapy. These cells, under appropriate culture conditions, can differentiate into a variety of cell lineages such as osteoblasts. chondrocyles, adipocytes, and neuronal cells. Based on their largeex vivo expansion capacity as well as their differentiation potential, UCB-derived multipotent stem cells may become a suitable source for clinical transplantation in tissue engineering and regenerative medicine. All modern protocols involve the use of cytokines with chemotherapy in order to increase the circulation of stem cells in the blood. Because UCB, in general, produce less cytokine, or have a lower frequency of cytokine producing cells compared to adult stem cells, further research in cytokines related to the cell proliferation, cellular adhesion and cell migration is necessary to improve the understanding of the basic mechanisms of stem cell mobilization. This paper gives an overview of the cytokines produced by UCB-derived multipotent stem cells, and strongly suggests that cytokine induction and signal transduction is important for the differentiation of these cells.
