Novel tumor cell variants can be obtained by serially passaging tumor cells in different media and/or environments. Serial intraperitoneal (ip) passages of the Walker 256 tumor A variant was followed for studying the generation of its regressive AR variant. MHC class I molecule expression was assessed since variations in this molecule would explain changes(More)
The present study aimed at characterizing the subcutaneous development of the Walker 256 (W256) AR tumor, a regressive variant of the rat W256 A tumor. Wistar rats were injected subcutaneously with 4x10 W256 A or W256 AR tumor cells. The development of tumors was evaluated daily by percutaneous measurements. None of the W256 A tumors (n=20) regressed, but(More)
