简介：
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.
