stem cell based treatments are being increasingly explored for their possible potential to treat various cancers. mesenchymal stem cells believed to possess anti-tumor potential and are preferred for their properties like immune privileged nature, ability to migrate to the site of tumor and capability for multilineage differentiation. this tumor tropism property of mscs could be utilized to del...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

background mesenchymal stem cells (mscs) are ideal candidates for treatment of diseases. amniotic membranes are an inexpensive source of mscs (am-msc) without any donor site morbidity in cell therapy. adipose tissue derived stem cells (ascs) are also suitable cells for cell therapy. there is discrepancy in cd271 expression among mscs from different sources. in this study, the characteristics of...

background periodontium may be able to respond to injuries by regeneration via the function of stem cells. objectives this study sought to assess the differentiation of human periodontal ligament stem cells (pdlscs) into osteoblasts in standard osteogenic medium and in a medium supplemented with 1,25-dihydroxyvitamin d3 (calcitriol). materials and methods in this experimental study, pdlscs were...

background: in recent years we have successfully adopted an in vitro hepatogenic differentiation of mesenchymal stem cells (mscs). in this protocol the biologically active hepatocyte-like cells were differentiated from the stem cells isolated from either bone marrow or umbilical cord blood (ucb) samples. the aim of the present study was to compare the efficiency of the hepatogenic differentiati...

Background  Wisdom teeth are usually removed as a routine procedure for therapeutic or prophylactic reasons. Developing wisdom teeth are easy accessible source of stem cells during the adulthood which could be obtained. Methods  Search of the PubMed for stem cells and tooth was done. An inclusion criterion was extract of stem cells from wisdom tooth. Results  Stem cells can be obtained fro...

stem cell research has received considerable attention since the discovery that adult stem cells havethe capacity to form many different tissue types. stem cells are a booming field for the researchand have been extensively studied in the field of medicine, as well as dentistry. their applicationin oncology has been a boon to many of the patients. dental stem cells have been novel approachto tr...

Stem cells are undifferentiated cells that have the ability to convert to different types of cells and after dividing, they can produce their own cells or other cells. Axons of the retinal ganglion cells, from the optic nerve. These cells lose the ability to regenerate themselves before birth. Optic nerve degeneration can result from various causes including increased intraocular pressure, comp...

background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...

Stem cells are self-renewing cells that can be differentiated into other cell types. Conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2D) cultures. The design of three-dimensional (3D) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...
