Differentiation of cryopreserved human umbilical cord blood-derived stromal cells into cells with an oligodendrocyte phenotype

In this study, we examined the phenotypic characteristics of human umbilical cord blood-derived mesenchymal stromal cells (UCB-derived MSCs) differentiated along an oligodendrocyte pathway. We induced human UCB-derived MSCs to form floating neurospheres, and these neurospheres were then induced to differentiate into oligodendrocyte progenitor-like cells using multiple induction factors. Differentiated UCB-derived MSCs showed morphologic characteristics of an oligodendrocyte phenotype. The expression of cell surface markers characteristic of oligodendrocyte progenitor cells or oligodendrocytes was determined by immunocytochemical staining. These results suggest that human UCB-derived MSCs can be induced to differentiate into cells with an oligodendrocyte phenotype and that these cells may have potential in the future cellular therapy of central neurological disorders.
