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...

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....

This study was designed to establish a more effective and safe culture system for adoptive immunotherapy by investigating the use of homologous cord blood plasma (HCBP) instead of fetal bovine serum (FBS), which has various limitations including ethical problems for the ex vivo expansion of human umbilical T lymphocytes. Fresh human umbilical mononuclear cell fractions were isolated by Ficoll-H...

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...

Background: Abnormal umbilical cord pH can be indicated a distress imposed of newborn and can also be useful in determining the prognosis of the newborn. There are different views about the effect of the neonatal delivery method on the blood gas analysis of the umbilical artery. This study aimed to determine the effect of the method of delivery on umbilical artery pH. Methods: In this Cross ...

in recent years, considerable advances have been made in the field of regenerative medicine. unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. it h...

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 injure...

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...
