Interrogating the impact of metabolism during development is important for understanding cellular and tissue formation, organ and systemic homeostasis, and dysregulation in disease states. To evaluate the vital functions metabolism coordinates during human brain development and disease, pluripotent stem cell-derived models, such as organoids, provide tractable access to neurodevelopmental processes. Despite many strengths of neural organoid models, the extent of their replication of endogenous metabolic programs is currently unclear and requires direct investigation. Studies in intestinal and cancer organoids that functionally evaluate dynamic bioenergetic changes provide a framework that can be adapted for the study of neural metabolism. Validation of in vitro models remains a significant challenge; investigation using in vivo models and primary tissue samples is required to improve our in vitro model systems and, concomitantly, improve our understanding of human development.
探讨发育过程中代谢的影响对于理解细胞和组织形成、器官和系统稳态以及疾病状态下的失调非常重要。为了评估代谢在人类大脑发育和疾病过程中协调的重要功能,多能干细胞衍生的模型,如类器官,为神经发育过程提供了可行的方法。尽管神经类器官模型有许多优点,但它们对内源性代谢程序的复制程度目前尚不清楚,需要进行直接研究。在肠道和癌症类器官中进行的功能评估动态生物能量变化的研究提供了一个可以适应神经代谢研究的框架。体外模型的验证仍然是一个重大挑战;需要使用体内模型和原代组织样本进行研究,以改进我们的体外模型系统,并相应地提高我们对人类发育的理解。
