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
Regenerating protein family Regenerating protein family The regenerating protein family often abbreviated as Reg family are a group of small secretory proteins that are involved in the proliferation and differentiation of diverse cell types. In addition they are important in protecting cells from death caused by damage or inflammation. There are seven types of Reg genes present in the mouse mainly located on chromosome 6 but only five (REG1A, REG1B, REG3A, REG3G, and REG4) have been shown to be present in the human on chromosome 2. Reg proteins are involved in the growth and differentiation of cells from various organs under normal and
