Abstract (original English)
It is known that umbilical cord blood (UCB) is a rich source of stem cells with practical and ethical advantages. Three important types of stem cells which can be harvested from umbilical cord blood and used in disease treatment are hematopoietic stem cells (HSCs), mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs). Since these stem cells have shown enormous potential in regenerative medicine, numerous umbilical cord blood banks have been established. In this study, we examined the ability of banked UCB collected to produce three types of stem cells from the same samples with characteristics of HSCs, MSCs and EPCs. We were able to obtain homogeneous plastic rapidly-adherent cells (with characteristics of MSCs), slowly-adherent (with characteristics of EPCs) and non-adherent cells (with characteristics of HSCs) from the mononuclear cell fractions of cryopreserved UCB. Using a protocol of 48 h supernatant transferring, we successfully isolated MSCs which expressed CD13, CD44 and CD90 while CD34, CD45 and CD133 negative, had typical fibroblast-like shape, and was able to differentiate into adipocytes; EPCs which were CD34, and CD90 positive, CD13, CD44, CD45 and CD133 negative, adherent with cobble-like shape; HSCs which formed colonies when cultured in MethoCult medium.
