The Important Role of FLT3-L in Ex Vivo Expansion of Hematopoietic Stem Cells following Co-Culture with Mesenchymal Stem Cells
OBJECTIVE Hematopoietic stem cells (HSCs) transplantation using umbilical cord blood (UCB) has improved during the last decade. Because of cell limitations, several studies focused on the ex vivo expansion of HSCs. Numerous investigations were performed to introduce the best cytokine cocktails for HSC expansion The majority used the Fms-related tyrosine kinase 3 ligand (FLT3-L) as a critical co...
متن کاملEx vivo Expansion and Differentiation of Mesenchymal Stem Cells from Goat Bone Marrow
Objective(s) Mesenchymal stem cells (MSCs) from large animals as goat which is genetically more closely related to human have rarely been gained attentions. The present study tried to isolate and characterize MSCs from goat bone marrow. Materials and Methods Fibroblastic cells appeared in goat marrow cell culture were expanded through several subcultures. Passaged-3 cells were then different...
متن کاملCo-culture of Umbilical Cord-derived Hematopoietic and Mesenchymal Stem Cells on Protein-Coated poly-L-Lactic Acid Nanoscaffolds
Background and purpose: Umbilical cord blood (UCB) is a source of Hematopoietic stem cells (HSCs) and has received a lot of attention due to its availability, renewal capacity, proliferation rate, and differentiation potential. The main limitation of using these cells is their low quantity in one unite of UCB. To overcome this, HSCs co-culturing with UCB derived mesenchymal cells (MSCs) is a pr...
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 کاملNanofiber Expansion of Umbilical Cord Blood Hematopoietic Stem Cells
Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...
متن کاملModelling 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...
