Trasplante de células precursoras de interneuronas derivadas de humanos en el hipocampo de la cría de ratón

Executive Industry Relevance

Restoring excitatory-inhibitory balance in the hippocampus addresses a core pathophysiological mechanism in neurodevelopmental disorders, offering a predictive model for target validation. This approach enables mechanistic de-risking by testing whether cellular integration rescues circuit dysfunction, informing go/no-go decisions in early discovery. The method supports translational continuity by providing a disease-relevant system to evaluate precursor cell therapies before preclinical investment.
