embryonic stem cells (escs) are originally derived from the icm of blastocysts and are characterized by their ability to self-renew and their pluripotencies. only a few reports have been published on esc isolations and line establishment in animals, even fewer in horses. however, it is still important to isolate equine escs for animal biotechnology and therapeutic applications. in the present s...

introduction: stem cell biology has been the subject of much recent discussion. embryonic stem (es) cells, derived from the inner cell mass of the blastocyst stage of early mammalian embryos are expected to become a powerful tool in future regenerative medicine and developmental biology due to their capacity of self-renewal and pluripotency. in the present study, the ultrastructural development...

In our previous review we reviewed the history of embryonic stem cells, advantages and disadvantages of ESC, parthenogenetic ESC and their therapeutic applications, cloning along with merits of SCNT, in this shot commentary we have just concentrated on induced pluripotent stem cells, mainly their transcriptomics, along with special emphasis on global transcriptomics in candidate oocyte factors ...

background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...

The function of metabolic state in stemness is poorly understood. Mouse embryonic stem cells (ESC) and epiblast stem cells (EpiSC) are at distinct pluripotent states representing the inner cell mass (ICM) and epiblast embryos. Human embryonic stem cells (hESC) are similar to EpiSC stage. We now show a dramatic metabolic difference between these two stages. EpiSC/...

background: mesenchymal stem cells (mscs) are important candidates for msc-based cellular therapy. current paradigm states that mscs support local progenitor cells in damaged tissue through paracrine signaling. therefore, study of paracrine effects and secretome of mscs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. this study ...

bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. recently, various stem cells, including embryonic stem cells (escs), bone marrow-derived mesenchymal stem cells (bm-mscs), umbilical cord blood-derived mesenchymal stem cells (ucb-mscs), adipose tissue-derived stem cells (adscs), muscle-derived stem cell...

Many of the earliest stem cell studies were conducted on cells isolated from tumors rather than from embryos. Of particular interest was research on embryonic carcinoma cells (EC), a type of stem cell derived from teratocarcinoma. The EC research laid the foundation for the later discovery of and subsequent work on embryonic stem cells (ESC). Both ESC isolated from the mouse (mESC) and then lat...

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...

Recent technological advances in cell reprogramming by generation of induced pluripotent stem cells (iPSC) offer major perspectives in disease modelling and future hopes for providing novel stem cells sources in regenerative medicine. However, research on iPSC still requires refining the criteria of the pluripotency stage of these cells and exploration of their equivalent functionality to human...
