Early Trial Tests Stem Cell Immunotherapy for Liver Cancer

(NLM.NIH.gov)

An early stage clinical trial by California Stem Cell Inc. in Irvine tested a therapy harnessing the body’s immune system to treat a common form of liver cancer. The trial, conducted with eight patients in Shanghai, China, showed the treatments were safe for patients with hepatocellular carcinoma and did not cause complications, according . . . → Read More: Early Trial Tests Stem Cell Immunotherapy for Liver Cancer
