The effect of ALA-PDT under normoxia and cobalt chloride (CoCl2)-induced hypoxia on adhesion molecules (ICAM-1, VCAM-1) secretion by colorectal cancer cells

Determination of tumor marker levels and especially adhesion molecules involved in metastatic spread is necessary. Our experiment reveals, that ALA PDT in normoxia and CoCl2-induced hypoxia has no effect on adhesion molecules secretion by colon cancer cells in vitro.
