Abstract
The article by Granjeiro et al provided a thorough review of the role of stem cell models in the development of advanced therapy medicinal products. It emphasized the potential of stem cell models to refine preclinical studies and align with regulatory requirements for clinical applications. This article introduced a new perspective on enhancing the transition of stem cell research into clinical practice, focusing on the importance of international regulatory harmonization and the need for standardization in stem cell-based therapies.
