Organoids derived from pluripotent stem cells exhibit notable similarities to organ development in vitro. Nonetheless, cardiac organoids generated to date possess immature phenotypes and are unable to model the full spectrum of heart development and disease. Here, we describe the developmental maturation of human heart organoids by controlled exposure to metabolic and hormonal factors over a 10-day period, mirroring key stages of human cardiac development and resulting in significant molecular, cellular, morphological, and functional changes. Overall, our findings represent a significant advancement in synthetic human heart development, offering a valuable platform for studying cardiac disease states and conducting pharmacological research.

摘要

Organoids derived from pluripotent stem cells exhibit notable similarities to organ development in vitro. Nonetheless, cardiac organoids generated to date possess immature phenotypes and are unable to model the full spectrum of heart development and disease. Here, we describe the developmental maturation of human heart organoids by controlled exposure to metabolic and hormonal factors over a 10-day period, mirroring key stages of human cardiac development and resulting in significant molecular, cellular, morphological, and functional changes.
