Abstract Background Two critical challenges in developing cell-transplantation therapies for injured or diseased tissues are to identify optimal cells and harmful side effects. This is of particular concern in the case of spinal cord injury where recent studies have shown that transplanted neuroepithelial stem cells can generate pain syndromes. Results We have previously shown that astrocytes derived from glial-restricted precursor cells GRPs treated with bone morphogenetic protein-4 BMP-4 can promote robust axon regeneration and functional recovery when transplanted into rat spinal cord injuries. In contrast we now show that transplantation of GRP-derived astrocytes GDAs generated by exposure to the gp130 agonist ciliary neurotrophic factor GDAsCNTF the other .
