Abstract:

BACKGROUND: Preservation media exert direct roles in stem cell activity and cell function, and there is still a lack of research on the preservation medium of human oligodendrocyte precursor cells worldwide.
OBJECTIVE: To evaluate the effect of clinically used preservation media on the viability of human oligodendrocyte precursor cells.
METHODS: Human oligodendrocyte precursor cells in logarithmic growth phase were cultured in human oligodendrocyte precursor cell complete medium, normal saline containing 1% albumin or normal saline for 24 hours at 4 °C. We then compared cell viability in different preservation media and cell proliferation ability after continuous culture.
RESULTS AND CONCLUSION: (1) Cell viability was counted by trypan blue staining 24 hours after cell storage. The results showed that the cell viabilities in the oligodenocyte complete medium group, the normal saline group containing 1% albumin group, and the normal saline group were 83%, 68%, and 51%, respectively. The cell viability was highest in the oligodenocyte complete medium group and lowest in the normal saline group. Cryopreserved cells were further cultured, and the cell proliferation ability was declined gradually, which was highest in the oligodenocyte complete medium group, followed by the normal saline containing 1% albumin, whereas the oligodendrocytes preserved in the normal saline could not continue to proliferate.
