简介：
Overview
This study introduces a protocol for obtaining CD34+ hematopoietic progenitors from leukofilter-derived sources and their subsequent in vitro differentiation into proplatelet-bearing megakaryocytes. This method aims to enhance the understanding of megakaryopoiesis and facilitates the analysis of the mechanisms regulating platelet production.
