Successful animal testing of drugs sometimes fails at the level of human trials. Karl Skorecki and Maty Tzukerman of the Technion-Israel Institute of Technology perform human drug trials by injecting human embryonic stem cells into lab animals.
At the lab, researchers formed a teratoma by injecting human stem cells into the hind legs of lab mice. They then inserted lab-grown cancer cells into the teratoma. It proliferated and spread to the different tissues in the artificial human cellular environment. It makes lab mice as shelter for testing anti-cancer drugs in human tissue.
So with this development, this research can provide better measurement of success of a drug, if uses in humans. It will save humans against different side effects.
