تقييم الطاقة الحيوية الخلوية في الخلايا الجذعية المكونة للدم للفأر والخلايا السلفية البدائية باستخدام محلل التدفق خارج الخلية

Overview

This study presents an optimized protocol for assessing cellular bioenergetics in non-adherent mouse hematopoietic stem and progenitor cells (HSPCs). Utilizing the extracellular flux analyzer, the protocol measures extracellular acidification rate (ECAR) and oxygen consumption rate (OCR) of HSPCs in real time, providing insights into their metabolic functions.
