Inhibitory effects of MSC on the in vivo pulmonary metastasis of hepatocellular carcinoma.

Variable	MSC injection	No MSC injection	P-value
No. of animals	8	9	N/A
Body weight, g	21.99±2.90^a	22.08±1.69^a	0.918
Tumor weight, g	2.90±0.80^a	2.86±0.72^a	0.906
Tumor weight/body weight, g	0.14±0.05^a	0.13±0.04^a	0.754
Lung metastasis, %	50%	100%	0.029
No. of lung metastases	1.37±1.60^a	1.77±0.97^a	0.263
Cellular no. of metastases	50.37±60.19^a	74.44±84.22^a	0.292

Student's t test was used to assess the statistical significance of differences in tumor weight, number of lung metastases and cellular numbers of metastases between the MSC injection group and no MSC injection group. Lung metastatic rate was evaluated using Fishers' exact test.
