Table 2 

The average number of invading cells in the three groups 

Groups 
CXCL12treated group (n = 4) 
Untreated control group (n = 4) 
AMD3100treated group (n = 4) 


Average number of invading cells 
169.7 ± 47.23# 
115.45 ± 26.49 
77.30 ± 33.30 
F value 
32.00 



# The differences of average number of invading cells between the CXCL12treated group and the control group is statistically significant. (P < 0.05).
