| Summary: | Background: Hematopoietic stem cell transplantation (HSCT) is a therapeutic approach for treatment of hematological malignancies and incompatibility of Bone marrow. Umbilical cord blood (UCB) has known as an alternative for hematopoietic stem/progenitor cells (HPSC) in allogeneic transplantation. The low volume of collected samples is the main hindrance in application of HPSC derived from umbilical cord blood. So, ex vivo expansion of HPSCs is the useful approach to overcome this restriction. The goal of using this system is to produce appropriate amount of hematopoietic stem cells, which have the ability of transplantation and long term haematopoiesis.
Material & Methods: In current study CD133+ cells were isolated from cord blood (CB). Isolated cells were seeded on microwells. Then expanded cells proliferation rate and ability in colony formation were assessed and finally were compared with 2 Dimensional (2D) culture systems.
Results: Our findings demonstrated that CD133+ cells derived from UCB which were cultivated on microwells had significantly higher rate of proliferation in compared with routine cell culture systems.
Conclusion: In Current study, it was shown that CD133+ cells’ proliferations which were seeded on PDMS microwells coated with collagen significantly increased. We hope that 3 dimensional (3D) microenvironment which mimics the 3D structure of bone marrow can solve the problem of using UCB as an alternative source of bone marrow. |
