Table 3. The flow cytometry results of surface markers from BMSCs in different generation.

generation	CD29(+)	CD44(+)	CD45(−)
P₀	73.10%	69.74%	99.68%
P₁	99.44%^▴	99.96^▾	95.81%
P₂	99.49%^▴	99.52^▾	99.93%

^▴

there were significant difference in the positive rate of CD29 compared with p₀ group.

^▾

there were significant difference in the positive rate of CD44 compared with p₀ group. There was no significant difference of the negative rate of CD45 among p₀, p₁, p₂ groups.
