With the aim of establishing an effective method to expand hematopoietic stem/progenitor cells for application in hematopoietic stem cell transplantation, we performed ex vivo expansion of hematopoietic stem/progenitor cells derived from mouse fetal liver cells in three-dimensional cocultures with stromal cells. In these cocultures, stromal cells were first cultured within three-dimensional scaffolds to form stromal layers and then fetal liver cells containing hematopoietic cells were seeded on these scaffolds to expand the hematopoietic cells over the 2 weeks of coculture in a serum-containing medium without the addition of cytokines. Prior to coculture, stromal cell growth was suppressed by treatment with the DNA synthesis inhibitor mitomycin C, and its effect on hematopoietic stem/progenitor cell expansion was compared with that in control cocultures in which fetal liver cells were cocultured with three-dimensional freeze-thawed stromal cells. After coculture with mitomycin C-treated stromal cells, we achieved a several-fold expansion of the primitive hematopoietic cells (c-kit+hematopoietic progenitor cells >7.8-fold, and CD34+hematopoietic stem/progenitor cells >3.5-fold). Compared with control cocultures, expansion of hematopoietic stem/progenitor cells tended to be lower, although that of hematopoietic progenitor cells was comparable. Thus, our results suggest that three-dimensional freeze-thawed stromal cells have higher potential to expand hematopoietic stem/progenitor cells compared with mitomycin C-treated stromal cells.
