context stem cells have the potential to generate a renewable source of cells for regenerative medicine due to their ability to self-renew and differentiate to various functional cell types of the adult organism. the extracellular microenvironment plays a pivotal role in controlling stem cell fate responses. therefore, identification of appropriate environmental stimuli that supports cellular p...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

Background: Keratinocyte stem cell is one of the adult stem cells that inhabits the skin and contributes to skin function and renewal. Adult stem cells are best defined by their capacity to self-renew, and to maintain tissue function for a long period of time. These findings indicate the importance of these cells for clinical applications including regenerative medicine, tissue engineering and ...

stem cells are undifferentiated self regenerating multi potential cells. there are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. totipotent: these stem cells can form an entire organism such as fertilized egg. ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organis...

stem cell therapy can be useful for spinal cord injury (sci). induced pluripotent stem cells (ipscs) are generated by reprogramming mature, fully differentiated cells into a pluripotent state. the ability to generate pluripotent cells from adult somatic cells without the need for an embryo was a major development in stem cell biology. ipscs were established from mouse fibroblasts and demonstrat...

a common pathological process that occurred after brain injury is gliosis. gliosis involves the activation of glial cells to proliferate and become hypertrophic to occupy the injured brain areas. in order to form a defense system against the invasion of micro-organisms and cytotoxins into surrounding tissue, glial cells including astrocytes and microglia undergo reactive response to injury. neu...

stem cells are the cells having some distinguishing characteristics like longevity, high capacity of self-renewal and differentiation, quiescence and highly error-free proliferation. almost all stem cells have the potential of lineage reprogramming, i.e. inter-conversion of cell lineages. they also have the potential to differentiate into almost all kinds of cells. these cells have been found i...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...
