چکیده

Let it grow: The conjugated polymer poly(3,4-ethylenedioxythiophene) (PEDOT) was synthesized with heparin as the counterion to form a cell culture substrate. The surface of PEDOT:heparin in the neutral state associated biologically active growth factors. Electrochemical in situ oxidation of PEDOT during live cell culture decreased the bioavailability of the growth factor and created an exact onset of neural stem cell differentiation.

The effect of Fibroblast Growth Factor-2(FGF-2) and retinoic acid on differentiation of mouse embryonic stem cells into neural cells

Introduction: Embryonic Stem (ES) cells as pluripotent cells derived from the inner cell mass of blastula can differentiate to neural cells in vitro and this property is valuable in studies of neurogenesis and in the generation of donor cells for transplantation. In this regard, the propose of this research, was the study of the role of two important factors in the development of neural syst...

Isolation and Differentiation of Neural Stem/Progenitor Cells From Subventricular Zone of One Adult Rat

Introduction: In adult mammalian brain, neural stem cells are isolated from both the dentate gyrus and subventricular zone. This study aimed to isolate neural stem cells from adult rat subventricular zone and differentiate them into neurons and astrocytes.  Methods: In this study, the whole brain was removed after full anesthesia and creating cervical dislocation. Under a microscope, subv...
