Abstract
Fresh human whole bone marrow aspirates (25 mL; AllCells) were collected and processed on the same day. Mononuclear cells were isolated by Ficoll density gradient centrifugation followed by red blood cell lysis. CD34⁺ hematopoietic stem and progenitor cells were enriched by magnetic selection (STEMCELL Technologies, catalog # 17856). Equal numbers of CD34⁺ and CD34⁻ cells (5×10⁵ each) were then pooled at a 1:1 ratio. Nuclei were extracted following the 10x Genomics Single Cell Multiome nuclei isolation protocol (see links below), generating high-quality nuclei suitable for downstream ATAC + gene expression multimodal profiling.
