The pitfalls of xenotransplantation

By SHREYA TIWARI | October 31, 2024

A chimera is an organism composed of cells from two or more distinct genotypes. Human-animal chimeras are a budding area of research and involve the introduction and growth of human tissues in an animal. Chimerism research holds great promise in improving the availability of organs for organ transplantation, which is a major issue due to the current severe organ shortage. Initial chimerism studies involved smaller organisms, such as one where researchers attempted to grow a rat pancreas in a mouse.
