Modelling of ex vivo expansion/maintenance of hematopoietic stem cells.
In this study, we described the modelling of the expansion/maintenance of human hematopoietic stem/progenitor cells from adult human bone marrow. CD 34(+)-enriched cell populations from bone marrow were cultured in the presence and absence of human stroma in serum-free media containing bFGF, SCF, LIF and Flt-3 ligand for several days. The cells in the culture were analysed for expansion and phe...
متن کاملEx vivo expansion of human hematopoietic stem and progenitor cells.
Despite progress in our understanding of the growth factors that support the progressive maturation of the various cell lineages of the hematopoietic system, less is known about factors that govern the self-renewal of hematopoietic stem and progenitor cells (HSPCs), and our ability to expand human HSPC numbers ex vivo remains limited. Interest in stem cell expansion has been heightened by the i...
متن کاملHOXB4-Induced Expansion of Adult Hematopoietic Stem Cells Ex Vivo
Hox transcription factors have emerged as important regulators of primitive hematopoietic cell proliferation and differentiation. In particular, HOXB4 appears to be a strong positive regulator of hematopoietic stem cell (HSC) self-renewal. Here we demonstrate the potency of HOXB4 to enable high-level ex vivo HSC expansion. Cultures of nontransduced or GFP-transduced murine bone marrow cells exp...
متن کاملEx Vivo Expansion of Umbilical Cord Blood Hematopoietic Stem Cells on Collagen- Fibronectin Coated Electrospun Nano Scaffold
Background and Objective: Umbilical Cord blood (UCB) hematopoietic stem cell (HSC) transplantation is a therapeutic approach for the treatment of malignant and non-malignant hematologic disorders due to ease of collection, lack of risk for donors and lower levels of infection. Moreover, it is considered a good alternative for bone marrow HSC transplantation. The main limitation of their use is ...
متن کاملEx vivo expansion of hematopoietic stem cells: mission accomplished?
A small number of hematopoietic stem cells (HSCs) with self-renewal and multi-lineage repopulation capacity maintain hematopoiesis during the lifetime of an individual. Moreover, HSCs and their potential exist in excess as one individual can share its HSCs with another leading to creation of a genetically identical hematopoietic system. For over half a century this property of HSCs has been uti...
