Plastic-adherent BMSCs may be insufficient to preserve primitive HSCs. Here, we describe a method of isolating and culturing human BMSCs as nonadherent mesenchymal spheres. Human mesenspheres were derived from CD45- CD31- CD71- CD146+ CD105+ nestin+ cells but could also be simply grown from fetal and adult BM CD45--enriched cells. Human mesenspheres robustly differentiated into mesenchymal lineages. In culture conditions where they displayed a relatively undifferentiated phenotype, with decreased adherence to plastic and increased self-renewal, they promoted enhanced expansion of cord blood CD34+ cells through secreted soluble factors. Expanded HSCs were serially transplantable in immunodeficient mice and significantly increased long-term human hematopoietic engraftment. These results pave the way for culture techniques that preserve the self-renewal of human BMSCs and their ability to support functional HSCs. eng Self-renewing human bone marrow mesenspheres promote hematopoietic stem cell expansion journal article 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 URL https://repisalud.isciii.es/bitstreams/8037d0ec-c469-4c50-a0a0-4650f0dab3a2/download File MD5 39eeef139617d4e86ec4f2c9a9b7ae7f 5887551 application/pdf Isern_2013_AND_SUpp1-s2.0-S2211124713001654-main.pdf URL https://repisalud.isciii.es/bitstreams/f2d176ae-81c8-4a8c-a8bd-2a04a6f46573/download File MD5 778879e91e074909377b62dfcd464a06 73389 text/plain Isern_2013_AND_SUpp1-s2.0-S2211124713001654-main.pdf.txt
