From Wikipedia, the free encyclopedia

A humster is a hybrid cell line made from a zona-free hamster oocyte fertilized with human sperm.[1] It always consists of single cells, and cannot form a multi-cellular being. Humsters are usually destroyed before they divide into two cells; if isolated and left alone to divide, they would still be unviable.[2]

Humsters are routinely created mainly for two reasons:

Somatic cell hybrids between humans and hamsters or mice have been used for the mapping of various traits since at least the 1970s.[3]
