Spinal cord injury research triggering an immune system response. Animal studies with injection of bone marrow stem cells have shown improvement in motor function; however not so in a human trial a year post-injury. More trials are underway. Adipose and umbilical tissue stem cells need further study before human trials can be performed, but two Korean studies were begun to investigate adipose cells in SCI patients. Transplantation of tissues such as olfactory ensheathing cells from the olfactory bulbs has been shown to produce beneficial effects in spinal cord injured rats. Trials have also begun to show success when olfactory ensheathing cells are transplanted into
Human cloning Research is underway to potentially use stem cell therapy to treat heart disease, diabetes, and spinal cord injuries. Regenerative medicine is not in clinical practice, but is heavily researched for its potential uses. This type of medicine would allow for autologous transplantation, thus removing the risk of organ transplant rejection by the recipient. For instance, a person with liver disease could potentially have a new liver grown using their same genetic material and transplanted to remove the damaged liver. In current research, human pluripotent stem cells have been promised as a reliable source for generating human neurons, showing the potential
