Modelado de enfermedades mitocondriales utilizando organoides cerebrales: un enfoque en la encefalomiopatía mitocondrial, la acidosis láctica y los episodios similares a accidentes cerebrovasculares

Overview

This study explores the use of brain organoids as a model for Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-like episodes (MELAS). The research aims to understand the underlying pathophysiology of MELAS and facilitate drug screening through organoid technology.
