The number of nucleated cells (NC), cell viability, and osteogenic ability before and after enrichment of bone marrow blood (n = 11). a The number of NC after enrichment was statistically lower than that in the original bone marrow blood (P < 0.01). b There was no difference in cell viability before and after enrichment (P > 0.05). c No significant changes in the osteogenic abilities were observed before and after enrichment. d There was no significant difference in osteogenic abilities before and after enrichment (P > 0.05)
