TRANSFORMED ENDOTHELIAL CELLS.

摘要

Endothelial cells which express a protein having I kappa B activity such that NF kappa B activation of the cells is substantially blocked may be prepared by altering the genetic material of the cells so that I kappa B activity is expressed continuously, immediately following endothelial cell activiting stimuli or on demand in response to a predetermined external stimulus e.g. by introducing heterologous I kappa B coding sequences or promoters into the cells. Organs and tissue comprising such endothelial cells are useful in transplantation e.g. xenotransplantation, as they are advantageously less susceptible to rejection.
