Since the first umbilical cord blood transplantation (CBT) in 1998, cord blood (CB) has now become one of the most commonly used sources of hematopoietic stem cells for transplantation. CBT has advantages of easy procurement, no risk to donor, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite human leukocyte antigen disp...
Umbilical cord blood transplantation (CBT) has been widely used as an alternative source of hematopoietic cell support for stem cell transplant patients. CBT offers several advantages over traditional stem cell sources, such as immediate availability, absence of risk for donors, lower risk of acute graft-versus-host disease, and a less stringent requirement for human leukocyte antigen matching....
Interest in umbilical cord blood as an alternative source of hematopoietic stem cells is growing rapidly. Umbilical cord blood offers the clinician a source of hematopoietic stem cells that are readily available and rarely contaminated by latent viruses. Moreover, the collection of umbilical cord blood poses no risk to the donor; there is no need for general anesthesia or blood replacement, and...
Among blood preparations, serum has been topically used in the management of various ocular diseases in ophthalmology. Like peripheral blood serum, umbilical cord blood serum contains a high concentration of essential tear components, growth factors, neurotrophic factors, vitamin A, fibronectin, prealbumin, and oil. Umbilical cord serum can provide basic nutrients for epithelial renewal and can...
We report a rare case of an umbilical cord hemangioma. The umbilical cord consisted of Capillaries and cavernous blood vessels and the hemangioma stressed umbilical arteries and vein. At 40 weeks of gestation, it resulted in intrauterine death of the fetus. Microscopically, there were lots of vessels with various thicknesses in the umbilical cord. Autopsy shows evidences of smothering. These fi...
BACKGROUND Mesenchymal stromal cells are employed in various different clinical settings in order to modulate immune response. However, relatively little is known about the mechanisms responsible for their immunomodulatory effects, which could be influenced by both the cell source and culture conditions. DESIGN AND METHODS We tested the ability of a 5% platelet lysate-supplemented medium to s...
Background: Hematopoietic stem cell transplantation (HSCT) is a therapeutic approach in treatment of hematologic malignancies and incompatibility of bone marrow. Umbilical cord blood (UCB) known as an alternative for hematopoietic stem/ progenitor cells (HPSC) for in allogenic transplantation. The main hindrance in application of HPSC derived from umbilical cord blood is the low volume of colle...
Backgrounds: Finding an efficient biomarker or combination of them as predictors of early-onset neonatal sepsis is very important. On the other hand, the use of umbilical cord blood samples in laboratory tests, along with its simplicity and availability, reflects neonate metabolic status. Background and Aim: The aim of this study was to investigate the association between umbilical cord bloo...
1. It has been suggested that lowdose prenatal mercury exposure as measured by umbilical cord blood mercury concentrations of >29 nmol/L causes adverse long-term neurocognitive outcomes. 2. Of 608 children, 491 (81%) had umbilical cord blood mercury concentrations of >29 nmol/L. However, umbilical cord blood mercury concentrations were associated with only two out of 23 neurocognitive subtests....
To clarify the maternal-fetal transfer of mercury across the placenta, inorganic and organic mercury were determined in 41 paired samples of maternal blood, placenta, umbilical cord blood and umbilical cord obtained from pregnant women who had no particular exposure to mercury compounds in their history. Both inorganic and organic mercury were detected in all the samples but the ratio of organi...
