Prospects for Brain Regenerative Medicine
(Thursday October 29 2009)
 | Will it be possible to use patient-derived cell transplants to heal the brain in much the same way as can be done with other organs? From EurekAlert!: researchers have "found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions and restoring function. ... We aimed at determining whether autografted cells derived from cortical gray matter, cultured for one month and re-implanted in the caudate nucleus of dopamine depleted primates, effectively survived and migrated. The autologous, re-implanted cells survived at an impressively high rate of 50 percent for four months post-implantation ... Researchers found that the cultured cells migrated, re-implanted into the right caudate nucleus, and migrated through the corpus callosum to the contralateral striatum. Most of the cells were found in the most dopamine depleted region of the caudate nucleus. This study replicated in primates the success the research team had previously reported using laboratory mice." |
