Umbilical cord blood is the blood found in the vessels of the umbilical cord and placenta. It has been shown that this blood contains at least three populations of stem cells, each with unique features and properties. Due to the absence of standardized criteria for characterizing and naming cord blood stem cells, different terms and acronyms have been introduced to describe certain cell populat...

stem cell therapy is a powerful technique for the treatment of a number of diseases. stem cells are derived from different tissue sources, the most important of which are the bone marrow (bm), umbilical cord (uc) blood and liver. human uc mesenchymal stem cells (huc-mscs) are multipotent, non-hematopoietic stem cells that have the ability to self-renew and differentiate into other cells and tis...

Limiting-dilution analysis of long-term culture-initiating cells (LTCIC) is a quantitative method of estimating hematopoietic stem cell activity in clinical samples. We compared the numbers of LTCIC in bone marrow (BM), umbilical cord blood, and blood progenitor cells (obtained from patients with solid tumors at leukapheresis after mobilization with induction chemotherapy and filgrastim adminis...

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...

PURPOSE To evaluate different protocols to isolate stem cells from ovine umbilical cord blood and adipose tissue. METHODS There were used 5 samples of umbilical blood and 5 samples of perirenal adipose tissue from 10 female sheep. All the samples were obtained through surgery, to harvest aseptic samples. There were used 3 protocols for obtainment and culture of umbilical cord blood stem cells...

OBJECTIVES The low frequency of survival of stem cells implanted in the myocardium after acute myocardial infarction may be caused by inflammation and oxidative stress in the myocardial microenvironment. We evaluated the effects of a traditional Chinese medicine, Compound Danshen Dripping Pills, on the cardiac microenvironment and cardiac function when used alone or in combination with human um...

il-22 is a member of il-10 cytokine family which is believed to play an important role in inflammatory responses. il-22 has similarities with il-10 including conserved sequences with il-10. il-22 receptor is also comprised of two chains known as l-22r1 and l-10r2; supporting the speculation that the two cytokines may have similar effects. the aim of this study was to shed some light on the biol...

backgroundresistin is reported as an antagonistic hormone of insulin and in the literature. nowadays, importance of resistin is being more highlighted in the metabolism of mother and fetus during pregnancy. this study aimed to assess the level of resistin in the umbilical cord and blood sugar at birth and evaluate the association of resistin and neonatal birth weight.materials and methodsthis c...

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 –se...

a quasi experimental study was conducted in the labour rooms of one of the hospital's of the university of   medical science of iran, to compare the effect ofcord blood drainage and oxytocin injection into the umblicat   vein in the duration of the third stage of labour.   a total of 180 women in the course of normal pregnancies with no complications and normal vaginal   dd ivery were sele...
