Stem cell research - a potentially vital area for the future treatment of spinal injury - has been the focus of a new study.
With the potential of embryonic stem cells in sharp focus for spinal cord injury treatment, a team of researchers has examined the difference between two types of stem cells.
Scientists from the Northwestern University Feinberg School of Medicine looked at the similarities between human induced pluripotent stem cells (hiPSCs) and human embryonic stem cells (hESCs).
It had been thought that these two types of stem cells were almost identical, but the researchers have found difference which may affect the potential for regenerative therapies - such as nerve regrowth in people who have suffered a spinal injury.
The study highlighted the lack of a biological regulator in the hiPSCs which may be an indicator of cancer.
A separate study of stem cell treatment found that there could be a risk of kidney damage from the therapy.
