From stem cells to grandmother cells: how neurogenesis relates to learning and memory.
Neurogenesis contributes thousands of new neurons each day to the hippocampus of the adult brain. Their production is influenced by numerous internal and external environmental factors, but their survival is especially sensitive to processes of learning. This commentary considers how learning enhances the survival of neural stem/progenitor cell progeny and what these new neurons might do once t...
متن کاملfrom stem cells to germ cells and from germ cells to stem cells
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...
متن کاملDifferntiation of Mesenchymal Stem Cells From Cord Blood to Osteblastic Cells
Purpose: This study was carried out to isolate mesenchymal stem cells from full-term cord blood and to differentiate these cells into osteoblastic cells. Materials and Methods: It this study, mesenchymal stem cells were isolated from cord blood and expanded by being cultured in the flask several times. First, the cord blood monoeuc1earcells were separated by ficoll - Hypac before they were cul...
متن کاملBlastema from rabbit ear contains progenitor cells comparable to marrow derived mesenchymal stem cells
Rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. The purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (MSCs). Five New Zealand white male rabbits were used in the present study. A 2-mm hole was created in the a...
متن کاملJurisprudential-Legal Approaches to Stem Cells Technology
Introduction: Along with the use of stem cells technology, many jurisprudential, moral, and legal challenges have been created, including the exploitation of women, intentional abortion, conversion embryos into commodities, stem cells trade, breaking the human dignity, and threats caused by biological agents. Elimination of such possible consequences requires drafting laws and legal mechanisms ...
