Umbilical cord blood is an established source of hematopoietic stem cells for transplantation. It enjoys several advantages over bone marrow or peripheral blood, including increased tolerance for Human Leukocyte Antigen mismatches, decreased incidence of graft-versus-host disease, and easy availability. Unrelated cord blood does have limitations, however, especially in the treatment of adults. ...

Introduction: The aim of study was to compare umbilical cord blood selenium levels in respiratory distress syndrome (RDS) and non RDS preterm babies.    Methods: Umbilical cord blood selenium levels of all preterm newborn born during a 6-month period were enrolled in the study. They were divided into two groups: RDS and non RDS. Selenium level was assessed by using electro-thermal atomic ab...

Spinal cord injury (SCI) unavoidably results in death of not only neurons but also glial cells. In particular, the death of oligodendrocytes leads to impaired nerve impulse conduction in intact axons. However, after SCI, the Schwann cells (SCs) are capable of migrating towards an area of injury and participating in the formation of functional myelin. In addition to SCI, cell-based therapy can i...

Newborn mononuclear cells are known to have increased suppressor activity when compared with adult cells. However, the precise phenotypic description of the suppressor cell subpopulation has not yet been reported. This study was designed to examine the surface markers on human cord blood cells as defined by monoclonal antibodies and to characterize cord blood mononuclear cells that suppress in ...

ess the relationship between umbilical cord blood gases at birth and morphology of umbilical cord, in a prospective study of 200 consecutive term delivery, we investigated the relationship between umbilical cord morphology characteristics (umbilical crd length, number of vascular coil, coiling index) and color of amniotic fluid and umbilical vessel blood gases. statistically significant linear ...

To evaluate the effectiveness of the human umbilical cord blood (HUCB) transplantation for the treatment of intrinsic sphincter deficiency (ISD), we analyzed the short term effects of HUCB mononuclear cell transplantation in rats with induced-ISD. ISD was induced in rats by electro-cauterization of periurethral soft tissue with HUCB mononuclear cell injection after 1 week. The sphincter functio...

The aim of the study was to evaluate therapeutic effectiveness of intra-arterial infusion of human umbilical cord blood (HUCB) derived cells at different stages of their neural conversion. Freshly isolated mononuclear cells (D-0), neurally directed progenitors (D-3) and neural-like stem cells derived from umbilical cord blood (NSC) were compared. Focal brain damage was induced in rats by stereo...

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...

he lack of maternal rejection of the allogenic fetus, suggests that adaptation of the immune system occurs during normal pregnancy. Umbilical cord blood (UCB) cells have unique properties to overcome the maternal rejection of allogenic fetus. Human umbilical cord blood cells (UCBC) has been shown to be an effective source in allogenic stem cell transplantation, however there is concern due for ...
