Stem cells stand up for themselves
Adult stem cells are not pampered pushovers. O'Reilly et al. report that certain stem cells take charge of their surroundings, molding their environment to control their division and differentiation. Some stem cells are cosseted like newborns. Neighboring cells cradle them in a structure called the niche. The niche not only nurtures its charges, it also dictates their behavior, determining whet...

متن کاملIsolation of Adipose Tissue Stem Cells with Organ Culture Method
Background Isolation of adipose tissue mesenchymal stem cells (MSCs) with current enzymatic methods has some limitations. For example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of MSCs. Also, it is accompanied with the increased risk of culture contaminations because of several handling steps.In this...
متن کاملDifferentiation of Adipose-derived Stem Cells into Schwann Cell Phenotype in Comparison with Bone Marrow Stem Cells
Objective(s) Bone marrow is the traditional source of human multipotent mesenchymal stem cells (MSCs), but adipose tissue appears to be an alternative and more readily available source. In this study, rat adipose-derived stem cells (ADSCs) were induced to differentiate into Schwann-like cells and compared with rat bone marrow stem cells (BMSCs) for their Schwann-like cells differentiation pote...
متن کاملWhat are Stem Cells?
Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...
