Various methods are currently under investigation to preserve fertility in males treated with high-dose chemotherapy and radiation for malignant and nonmalignant disorders. Human umbilical cord mesenchymal stem cells (HUC-MSCs), which possess potent immunosuppressive function and secrete various cytokines and growth factors, have the potential clinical applications. As a potential alternative, ...

Although human umbilical cord mesenchymal stem cells (hUC-MSCs) have been identified as a new source of MSCs for potential application in regenerative medicine, their full potential of differentiation has not been determined. In particular, whether they have the capability to differentiate into epithelial cells of endodermal origin such as the prostate epithelial cells is unknown. Here we repor...

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...

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...

Parkinson's disease (PD) is a neurodegenerative movement disorder that is characterized by the progressive degeneration of the dopaminergic (DA) pathway. Mesenchymal stem cells derived from human umbilical cord (hUC-MSCs) have great potential for developing a therapeutic agent as such. HGF is a multifunctional mediator originally identified in hepatocytes and has recently been reported to posse...

BACKGROUND MSCs are a promising therapeutic resource. Paracrine effects and the induction of differentiation patterns are thought to represent the two primary mechanisms underlying the therapeutic effects of mesenchymal stem cell (MSC) transplantation in vivo. However, it is unclear which mechanism is involved in the therapeutic effects of human umbilical cord-derived MSC (hUC-MSC) transplantat...

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 ...
