recently, the use of stem cells has expanded into numerous areas including cell therapy. in this study, we investigated the differentiation capacity of human wharton’s jelly stem cells (hwjscs) into lens fiber cells. morphological changes and expressions of four crystallin genes (αa, αb, βb1 and βb3) were studied. the bovine vitreous body has been shown to induce expression of crystallin genes ...

Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...

objective: human basic fibroblast growth factor (bfgf) plays an important role in cellular proliferation, embryonic development, and angiogenesis as well as in several signaling pathways of various cell types. bfgf is an essential growth factor for the maintenance of undifferentiated human embryonic stem cells (hescs) and human induced pluripotent stem cells (hipscs). materials and methods: in ...

background: bone marrow and umbilical cord stromal cells are multipotential stem cells that have the ability to produce growth factors that play an important role in survival and generation of axons. the goal of this study was to evaluate the effects of the two different mesenchymal stem cells on peripheral nerve regeneration. materials and methods: in this experimental study, a 10 mm segment o...

The ability to culture human stem cells long term, and possibly indefinitely, and to control how such cells specialise to form the different tissues of the body offers the possibility of major advances in healthcare. Stem cells have been isolated and cultured, but a great deal of research is required to develop cell lines which can generate replacement cells and tissues to treat many diseases.S...

Traumatic brain injury (TBI) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. The use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of TBI. In the present study, we surveyed the beneficial effec...

Objective: Arsenic, an environmental pollutant, decreases neuronal migration as well as cellular maturation and inhibits the proliferation of neural progenitor cells. Curcumin has been described as an antioxidant and neuroprotective agent with strong therapeutic potential in some neurological disorders. Human adipose-derived stem cells (hADSCs), a source of multipotent stem cells, can self-rene...

Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...
