background: tumor necrosis factor alpha (tnf-α) is a primary mediator of immune regulation and might be required in the early stages of dc development from cd34+ cells. however, details of optimal timing of exposure to tnf-α in dc development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of dcs remain to be valid...

background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

conclusions in a current study based on increasing maternal age, the hdl-c level in cord blood was decreased which is an independent risk factor for cvds in adulthood. results a statistically significant negative correlation was observed between cord blood hdl-c and maternal age (r = -0.18, p <0.01). there was no relationship between other lipids and lipoproteins with maternal age. our findings...

Cord blood is the blood that remains in the umbilical cord and placenta following birth, which is usually discarded It contains red blood cells, white blood cells, platelets, and plasma, like blood. In addition, cord blood is a rich source of stem cells that may have potentially lifesaving benefits for your baby and family. The cord blood of baby serves as an abundant source of stem cells. Thes...

background: dendritic cells (dcs) are the most potent stimulators of primary t cell responses and play a key role in immune reactions after stem cell transplantation. very little is known about the cord blood (cb) dendritic cells and their potential involvement in the low incidence and lower severity of acute graft-versus-host disease after cb transplantation.   objectives: the aim of this stud...

introduction: in 1989, the first successful umbilical cord blood transplantations (ucbts) was reported in a boy with fanconi's anemia, using umbilical cord (ucb) of his hla matched sister. cord blood transplantation is a good substitute for bone marrow or peripheral blood transplantation especially for children and small body size adults. methods: between 1998 and 2007 ,14 children(10 boys and ...

conclusions we found a relatively high value of tc and tg in our study. considering the relationship between high levels of lipids in the neonatal period and coronary artery disease in the adult population, we recommend future cohort studies for this statistical society. results of the 174 neonates, 97 were female. vaginal delivery was recorded in 79.8%. there were no significant differences re...

Cord blood is a sample of blood taken from a newborn baby&#039;s umbilical cord.Cord blood is collected because it is rich in stem cells content, such as hematopoietic cells, which can be used to treat hematopoietic and genetic disorders. Cord Blood Transplantation has been used in the treatment of over 80 diseases, including leukemia, lymphoma and anemia. Advantages of Cord Blood Treatment: • ...

stem cells are naïve or master cells. this means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. stem cells are found in many parts of the human body, although some sources have richer concentrations than others. some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and hu...

abstract background b cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. it has been shown that b cells produced successfully in the presence of stem cell factor (scf) and flt3 ligand (flt3l). il2, il7, and il15 cytokines as  -common family have an essential cytokines may support either synergistically or in an additi...
