By changing the color of systemic blood in the living animal with harmless dyes, and especially with lissamine green, it is possible to mark out regions of tumors which cannot readily be reached by blood-borne substances. These regions suddenly appeared in tumors, at a critical age, which in the transplanted mouse tumors studied (mammary carcinoma, sarcoma 37, Ehrlich-Landschiitz solid ascites) is about 12 days, and in the rat Walker carcinosarcoma about 5-10 days, depending on the type of host. A few days later these zones usually occupied all but a thin well-vascularized shell of the tumor, varying from a few millimetres in thickness to as little as one tenth of a millimetre. They often contained vessels with red blood in them when the blood in the rest of the body is green, showing that the vessels are blocked. These uncolored zones contained living cells, as shown by vital staining, tissue culture and particularly, by transplantation into new hosts. In 41 transplantations from these "white" zones, 23 typical tumors are produced, including all the tumor types tested. The penetration of dye into these so-called necrotic zones of tumors which contain living cells is determined at various time intervals after the blood was made green, and also after repeated daily injections of dye, and injections into the necrotic zone. In no case is a high concentration achieved throughout the necrotic zone. The movement of interstitial fluid, which might have carried the dye into the interior of the tumor, is retarded or prevented in tumors with necrotic centres, although each tumor behaved individually in this respect. The general significance of these findings is discussed in relation to tumor incorporation studies, the supposed "concentration" of dyes of tumors, the interpretation of tumor biochemical data and the action of anti-tumor agents.
