摘要: A novel three-dimensional culture system for the ex vivo expansion of human umbilical cord blood (CB) hematopietic progenitor cells (HPCs) was developed by growing CB mononuclear on highly porous CultiSpher G microspheres coated with bone marrow stromal in stirred flasks presence supplemented cytokines. After 12 days, number total viable cells, colony-forming units (CFU-C) and CD34+ present cultures reflected average increases 7.7, 23.3 9.6-fold, respectively, marked hematopoietic islands were formed surface G.
