One type of astrocyte was remarkably effective at promoting nerve regeneration and functional recovery, with transplanted animals showing very high levels of new cell growth and survival, as well as recovery of limb function.
"To our knowledge, this is the first time that two distinct sub-types of astrocytic support cells generated from a common stem cell-like precursor have been shown to have robustly different effects when transplanted into the injured adult nervous system," said researcher Margot Mayer-Proschel, from Rochester.
"It has long been a concern that therapies that promote growth of nerve fibres in the injured spinal cord would also cause sprouting in pain circuits," said Stephen.
"However by using the right astrocytes to repair spinal cord injuries we can have all the gains without the pain, while these other cell types appear to provide the opposite - pain but no gain," he added.
The study is published in the online Journal of Biology.
