The umbilical cord blood helps to regenerate the brain

By injecting umbilical cord blood in laboratory rats elderly, researchers at the University of South Florida (United States) have found improvements in the microenvironment of the hippocampus region of the brain of animals and a subsequent rejuvenation of neural progenitor stem cells . The results of their study are published in the digital edition of BMC Neuroscience.

"The neurogenesis of brain cells drops dramatically with increasing age, mostly by an impoverishment of the brain microenvironment," explained Alison Willing, an author of the study. "The increase in neurogenesis we get seems to be due to a decrease in inflammation."
Before this study, other research found that the USF reducing neuroinflamación in older rats by blocking the synthesis of pro-inflammatory cytokines IL-1 could regain some decline in neurogenesis associated with age and improve cognitive function. "The umbilical cord blood have similar potential to reduce inflammation and to restore some of the lost capacity of progenitor stem cells."
In this study, the number of cells increased proliferative within 24 hours after the injection of umbilical cord blood and this increase was maintained for at least fifteen days following a simple treatment.
"The injection of cells from umbilical cord blood can reduce neuroinflamación. Our results suggest the possibility that a cell therapy could become an effective approach to improve the microenvironment of the brain elderly and restore some lost skills."
