Table 1. Summary of fat pad xenograft tumor frequencies and volumes.

Cell Inoculated	Tumor Incidence	Tumor Volume (mm3)
S3	0/10	na
S3 + bMSC#3	0/10	na
T4	10/10	29.8 ± 5.1
T4 + bMSC#3	7/10	88.9 ± 19.6*
bASC#3	0/12	na

^*Indicates that the tumor volumes for T4/bMSC#3 mixed xenografts were statistically (p = 0.019) larger than the pure T4 xenografts. na: not applicable.
