Optical imaging of metastatic potential. Prostate tumors LAPC-4 and LAPC-9 are implanted and resected on reaching 1 cm (day 0). BLI is performed on day 20 then again on day 40. No metastases are evident from more indolent LAPC-9 tumors. LAPC-9 tumors would generate metastases after transfection with VEGF-C (data not shown). (Images courtesy of Dr. Lily Wu, UCLA.)
