قياس الكتلة المتقدريه والاغشيه المحتملة في الخلايا الجذعية التي تكون الدم وخلايا T بواسطة التدفق الخلوي

Overview

This study presents a reliable flow cytometry-based assay for measuring mitochondrial mass and membrane potential in living ex vivo cultured hematopoietic stem cells (HSCs) and T cells. The method is particularly useful for analyzing rare cell populations and can be combined with functional assays to evaluate HSC functionality.

Key Study Components

Research Area

• Cell Biology
• Hematopoietic Stem Cells
• Metabolic Profiling

Background

• Standard metabolic assays are ineffective for rare cell populations.
• Understanding mitochondrial function is crucial for enhancing HSC functionality.
• Previous literature lacks detailed protocols for low cell numbers.

Methods Used

• Flow cytometry for mitochondrial profiling
• Ex vivo cultured hematopoietic stem cells and T cells
• Use of nicotinamide riboside and TMRM staining for evaluating mitochondrial status

Main Results

• Nicotinamide riboside treatment increased TMRM low population and decreased TMRM fluorescence intensity in HSCs.
• Mitochondrial mass remained unchanged with treatment.
• The method successfully identifies specific cell populations through FACS analysis.

Conclusions

• This study provides a critical method for assessing metabolic fitness in HSCs.
• It's relevant for improving HSC function in bone marrow transplants and other therapeutic contexts.
