Background  The mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. Stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. This source of stem cells avoids invasive procedures and the ethical controversy of emb...

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...

objective: it is hypothesized that stem cells have the capability to form tumors after transplantation. spermatogonial stem cells have proliferation potency and colonization ability related to express pluripotency genes such as c-myc. the primary aim of this study is to investigate tumorigenicity ability of these cells after in vitro cultivation and inoculation in athymic animals. methods: sper...

objective: pulp and periodontal tissues are well-known sources of mesenchymal stem cells (mscs) that provide a promising place in tissue engineering and regenerative medicine. the molecular mechanisms underlying commitment and differentiation of dental stem cells that originate from different dental tissues are not fully understood. in this study, we have compared the expression levels of pluri...

It has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...

Introduction: Mesenchymal stem cells can be isolated from adult tissues, such as the adipose tissue, or other sources. Among all these sources, adipose tissue because of easy access, and placenta due to its immunomodulatory properties, in addition to another useful properties, were attracted more attention to themselves. Isolation and comparing these two different sources can help us for acces...

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...
