Black was an advocate for research using stem cells to repair damage from such conditions as cancer
Cancer
Cancer , known medically as a malignant neoplasm, is a large group of different diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the...

s of rats. The results were called "an incredible achievement" in opening the path to creating treatments for conditions that had been previously untreatable by using stem cells to create needed cells of different forms. Black's approach was to use neurons developed from the individual's own adult stem cells to avoid issues of transplant rejection
Transplant rejection
Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue. Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after...

, he served there as chairman of the department of neuroscience and cell biology. As director of the Stem Cell Institute, he expressed his frustration with federal opposition to embryonic stem cell research, stating that the therapies that could result from such studies had the potential to "get patients out of bed and out of wheelchairs" and that the researchers in the U.S. were trailing those elsewhere who were able to make further progress in their studies.
