简介：
Overview
This study presents a methodology for clonal analysis of hematopoietic stem cell precursors during murine embryonic development. The approach combines index sorting of single cells with endothelial cell co-culture and transplantation to assess the phenotypic properties and engraftment potential of these precursors.
