Cord blood stem cells revitalized part of the brain in aged rats.
Umbilical cord blood is known to contain stem cells that can be used for different clinical objectives (see HERE), especially in the promotion of cell banks. Now, a new possibility for the use of umbilical cord blood has been described. In a recent study published in Nature (see HERE), the authors report that human cord plasma when injected in the brains of rats revitalized the hippocampus and improves cognitive function in aged rats. These findings suggest that umbilical cord blood shows plasticity that could be used to treat hippocampal dysfunctions, especially those that are age-related. Since the use of umbilical cord blood presents no ethical difficulties, any new clinical application is considered welcome.
