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
Embryonic stem cell is the largest funder of stem cell-related research and development in the world. The award provides funding for Asterias to reinitiate clinical development of AST-OPC1 in subjects with spinal cord injury and to expand clinical testing of escalating doses in the target population intended for future pivotal trials. AST-OPC1 is a population of cells derived from human embryonic stem cells (hESCs) that contains oligodendrocyte progenitor cells (OPCs). OPCs and their mature derivatives called oligodendrocytes provide critical functional support for nerve cells in the spinal cord and brain. Asterias recently presented the results from phase 1 clinical trial testing of a
