Autologous stem cell therapy improves motor function in chronic stroke victims
Date:4/23/2014

Putnam Valley, NY. (Apr. 23, 2014) People who have had a stroke, often suffer motor deficits with little potential to restore neurological function. However, a study conducted in Taiwan, that will be published in a future issue of Cell Transplantation, but is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-ct1168Chen, has found that when one group of stroke victims had their own peripheral blood stem cells (PBSCs) injected directly into the brain and a similar group did not, those who received the PBSCs experienced some "improvement in stroke scales and functional outcome." Those in the PBSC-injected group also received injections of the growth factor granulocyte-colony stimulating factor (G-CSF), known to be potentially neuroprotective.

"In this phase 2 study, we provide the first evidence that intracerebral injection of autologous (self-donated) PBSCs can improve motor function in those who have suffered a stroke and have motor deficits as a result," said study corresponding Dr. Woei-Cheng Shyu of the Center for Neuropsychiatry, Graduate Institute of Immunology and Translational Medicine Research Center, China Medical University in Taiwan. "Our study demonstrated that this therapeutic strategy was feasible and safe in stroke patients who suffered a prior stroke, but within five years from the onset of symptoms."

According to the authors, there has been little advance made in restoring neurological function following ischemic stroke. However, since neuronal death is the primary mechanism that limits functional recovery, stem cell therapy is emerging as a potentially effective regenerative approach. Once more PBSCs are being increasingly used as a self-donated source for cell therapies for regenerating skeletal muscle, heart and neurons. The PBSCs may need to b
