Scripps Research recently published these findings in the journal Neuron. Through this study researchers discovered that stem cell replication decreases as brain activity increases. They also found that the protein Musashi1 possibly plays a role in regulating stem cell replication. As Musashi1 levels decrease, so does stem stell replication.
Does these finding mean that Musashi1 proteins could be used to stimlate repair in the adult brain? Or do these findings also suggest that stem cells used thearpeutically will self regulate as they begin to differentiate and brain activity increases? At a minimum this study suggests there are additional avenues to pursue for treatment of numerous neural diseases and conditions.
