...n for forming different types of neural tissue and promoting the reconnection of brain pathways. Using young, middle-aged and old rats, the researchers will transplant HUBC-derived cells into the subventricular region and hippocampus of the rodents' brains. These are the two areas of the brain where new neuron...Astrocytes play starring role in neural stem cell development

One intriguing implication of the experiments, said Stevens, is that astrocytes involvement in neuronal growth regulation might explain why neural stem cells can regenerate neurons in areas of the brain such a...Doubt cast on theory of tropical forest diversity
