new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...

Background: In recent decade, human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) provide enormous potential for appropriate cell therapy, but they have limited growth potential and cease to proliferate due to cellular senescence, so providing a strategy for increasing the stem cell survival is necessary.  Methods: In this investigation, MSCs characterized by flow cytome...

purpose : our aim was to isolate mesenchymal stem cells (mscs) from mouse umbilical cord and culture them with vitreous body to investigate their capacity to differentiate into lens fiber cells, crystallins are expressed. methods : wharton's jelly is the appropriate source of mscs. after isolation, the cells were cultured and alkaline phosphatase detection kit was used for staining undiffe...

Background and Objectives Mesenchymal stem cells (MSCs) are multipotent stem cells that can be isolated from umbilical cords and are therapeutically used because of their ability to differentiate into various types of cells, in addition to their immunosuppressive and anti-inflammatory properties. Fetal bovine serum (FBS), considered as the standard additive when isolating and culturing MSCs, ha...

BACKGROUND Umbilical cord infection developing subsequent to bacterial colonization is one of the outstanding reasons of newborn mortality and morbidity in underdeveloped and developing countries. OBJECTIVES This study aimed to evaluate the influence of sponge and tub bathing methods on umbilical cord separation time in full term babies in Turkey. PATIENTS AND METHODS This quasi-experimenta...

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 ...

OBJECTIVE To evaluate the risks and benefits of umbilical cord blood banking for future stem cell transplantation and to provide guidelines for Canadian perinatal care providers regarding the counselling, procedural, and ethical implications of this potential therapeutic option. OPTIONS Selective or routine collection and storage of umbilical cord blood for future autologous (self) or allogen...

Delayed clamping of the umbilical cord is recommended for term and preterm infants who do not require resuscitation. However, the approach to the newly born infant with signs of fetal compromise, prematurity and extremely low birthweight, or prolonged apnea is less clear. Human and experimental animal data show that delaying the clamping of the umbilical cord until after the onset of respiratio...
