Rate of liver metastasis formation and observation by intravital TPLSM.

	RFP-HT29 cells in GFP nude mice
Liver metastases after intrasplenic inoculation	70%a (12/17)b at 8 weeks
Observation of metastasis by intravital TPLSM	67%c (8/12)d at 8 weeks

^aPercentage of liver metastases after intrasplenic inoculation.

^bThe number of mice with liver metastases/the number of mice avaiable at the indicated time points.

^cPercentage of successful observation of metastatic colonies by intravital TPLSM.

^dThe number of mice successfuly observed metastatic colonies by intravital TPLSM/the number of mice with liver metastases.
