many investigators have used xenogeneic, especially murine stromal cells and fetal calf serum to maintain and expand human stem cells. the proliferation and expansion of human hematopoietic stem cells in ex vivo culture were examined with the goal of generating a suitable protocol for expanding hematopoietic stem cells for patient transplantation. using primary fetal liver cells, we established...
ex vivo expansion of human umbilical cord blood cells (hucbc) is explored by several investigators to enhance the repopulating potential of hucbc. the proliferation and expansion of human hematopoietic stem cells (hsc) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding hsc for patient transplantation. using primary human mesenchymal stem cells...
stem cell therapy is a powerful technique for the treatment of a number of diseases. stem cells are derived from different tissue sources, the most important of which are the bone marrow (bm), umbilical cord (uc) blood and liver. human uc mesenchymal stem cells (huc-mscs) are multipotent, non-hematopoietic stem cells that have the ability to self-renew and differentiate into other cells and tis...
cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. cord blood banking requires accurate steps in donor selection, cord blood ...
A study of the susceptibility of human peripheral blood mononuclear cells to measles virus infection and replication is reported. Resting lymphocytes obtained from adults showed very low levels of infection and virus replication while lymphocytes activated by plant mitogens or allogenic lymphocytes supported mononuclear cells obtained from the umbilical cord of healthy neonates were more suscep...
objective(s): the present day challenge is how to obtain germ cells from stem cells to treat patients with cancer and infertility. much more efforts have been made to develop a procedure for attaining germ cells in vitro. recently, human umbilical cord-derived mesenchymal stem cells (humscs) have been introduced with higher efficacy for differentiation. in this work, we tried to explore the eff...
Since the events of ionizing radiation damage increasingly, the human healthy are threatened by radiation. With the development of cells regeneration, stem cells applied in therapy for radiation injury become a hotspot in recent years. Then we are aimed to study on experimental animals to human umbilical cord blood stem cells of ionizing radiation-induced hematopoietic injury. The 80 mice were ...
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 assess the pur...
Objective(s) Human umbilical cord blood (HUCB) is now considered as a valuable source for stem cell–based therapies. Previous studies showed that intravascular injection of the HUCB significantly improves neurological functional recovery in a rat model of intracerebral hemorrhage (ICH). In the present study, we hypothesize transplanted HUCB derived mononuclear cells (UC-MCs) can decrease injur...
Human umbilical cord blood is frequently used as a source of transplantable hematopoietic cells and more recently as a target of gene therapy - a new approach for treatment of various disorders. The aim of our study was optimisation of the transfection conditions of cord blood-derived CD34(+) hematopoietic cells. Mononuclear cells fraction was isolated from cord blood samples by density gradien...
