경쟁 이식은 조혈 줄기 세포의 체력을 평가하는

Overview

This protocol provides step-by-step guidelines for setting up competitive mouse bone marrow transplant experiments to study hematopoietic stem/progenitor cell function without prior purification of stem cells by cell sorting. The method aims to determine the fitness of bone marrow hematopoietic stem cells in vivo using a competitive transplant assay.

Key Study Components
