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 ...

cortical spreading depression (csd) has been suggested to underlie some neurological disorders such as migraine. despite the intensity with which many investigators have studied sd in the brain, only a few studies have aimed to identify sd in the spinal cord. here we described the main characteristic features of sd in the spinal cord induced by different methods including various spinal cord in...

background: hemoglobin (hb) and hematocrit (hct) have been used routinely in the diagnosis of neonatal anemia and polycythemia.   objective: to measure the cord blood hb and hct and to determine their association with maternal hb and hct.   methods : 170 healthy neonates born through normal vaginal delivery with gestation age of 37-42 wks and birth weight of 2.5-4 kg, and their mothers were inc...

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...

conclusions since wetting of umbilical cord during tub bathing delays the separation of umbilical cord, sponge bathing is recommended for newborns until the umbilical cord falls off. results the time of separation of umbilical cord in babies who were given sponge bathing (6.1 ± 1.4) was shorter compared to those given tub bathing (8.3 ± 2.5) (p < 0.005). patients and methods this quasi-experime...

compound action potential (cap) of spinal cord represents valuable properties of neural fibers including excitability, rate of myelination and membrane integrity. these properties are measured using amplitude, latency and area under curve of caps recorded from spinal cord. here, the isolated spinal cord was set in a double sucrose gap (dsg) chamber and its response to intracellular stimulation ...

Cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. Increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. Cord blood banking requires accurate steps in donor selection, cord blood ...

abstractbackground: fetal bovine serum (fbs) is widely used in cell culture laboratories,risk of zoonotic infections and allergic side effects create obstacles for its use inclinical trials. therefore, an alternative supplement with proper inherent growthpromotingactivities is demanded.objective: to find fbs substitute, we tested human umbilical cord blood serum(hucs) for proliferation of human...
