Selective tropism of liver stem cells to hepatocellular carcinoma in vivo

Table 1 Comparison of c-kit and SDF-1 expression in liver tissue and HCC n (%)

Tissue	n	c-kit	SDF-1
Control	14	0 (0)	5 (36.7)
HCC	15	11 (73.3)b	6 (40.0)

^bP < 0.01 vs control group.

Table 2 The effect of different approaches of transplantation on the distribution of liver stem cells in tumor lesion

Group	n	(-)	(+)	(++)	(+++)
Portal veina	9	0	2	4	3
Hepatic artery	9	2	5	2	0
Caudal vein	8	1	5	2	0
Pericancerous tissue	9	1	5	2	1

H = 8.832,

^aP = 0.032 < 0.05 vs other three approaches groups.
