germline and somatic stem cells are distinct types of stem cells that are dedicated to reproduction and somatic tissue regeneration, respectively. germline stem cells (gscs), which can self-renew and generate gametes, are unique stem cells in that they are solely dedicated to transmit genetic information from generation to generation. we developed a strategy for the establishment of germline st...

background: umbilical cord tissue is a very rich source of mesenchymal stem cells. instead of discarding this source we are banking the tissue along with cord blood for possible future cell based applications. the cord tissue needs to be transported and stored properly in order for it to be good enough for cell isolation at a later date. in this paper we have carried out a validation study to d...

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...
