Study finds the mechanism used by metastatic cancer cells to infiltrate the liver

The liver sinusoidal endothelial cells (LSECs, beige) surround a blood vessel containing a cancer cell (green). The cancer cell is able to induce the formation of intracellular gaps (iGaps, red), through inducing MMP9. Credit: Matsubara, Osaka Metropolitan University Metastasis—when cancer spreads to form new tumors—causes approximately 90% of cancer-related deaths. Because metastatic cancer cells circulate… Continue reading Study finds the mechanism used by metastatic cancer cells to infiltrate the liver
