Scientists are beginning to understand what makes some stem cells safe for transplantation and some not so safe (e.g., they form tumors after transplantation). A recent study published in PNAS by Okano and colleagues shows that, in mice, certain induced pluripotent stem cells (iPS) are not only safe for transplantation but also that they differentiated into neural-type cells and promoted functional improvement following spinal cord injury (SCI).
The authors suggest that these "safe" iPS cells may be a promising cell source for therapy following SCI.
