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...

the human placenta has long been the subject of scientific interest due to the important roles which it performs during pregnancy in sustaining the fetus and maintaining fetomaternal tolerance. more recently, however, researchers have begun to investigate the possibility that the placenta’s utility may extend beyond fetal development to act as a source of cells with clinically relevant properti...

embryonic stem cells (escs) are pluripotent, self-renewing cells. these cells can be used in applications such as cell therapy, drug discovery, disease modelling, and the study of cellular differentiation. in this experimental study embryonic stem cells cultured in the laboratory and were amplified. total rna was extracted from cells and converted to cdna by reverse transcription-polymerase cha...

allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...

Background and purpose: Angiogenesis provides proper nutrition and helps to the development and spread of cancer cells. Cancer stem cells are a rare population of tumor cells responsible for initiation, spreading and growth of cancer. Angiogenesis occurs more in cancer stem cells compared with other cancer cells. Ibuprofen, as a member of nonsteroidal anti-inflammatory drugs (NSAIDs) group is u...
