Astrocytes in the central nervous system and their functions in health and disease: A review

Figure 1 Human astrocytes. A: The primary culture of human astrocytes. Images: Zeiss Axiovert 40 inverted microscope, × 50 magnification. Scale bar = 200 μm. Original figure taken by the authors; B: The immunocytochemical characterization of adult human astrocytes. Morphology of the cells was determined with a fluorescent phalloidin conjugate, which binds selectively to actin filaments (red). In low-density cultures, adult astrocytes exhibit a polygonal form with actin filaments adjacent to the cell membrane. Nuclei were counter-stained with 4',6-diamidino-2-phenylindole (blue). Images: EVOS FL fluorescence microscope, × 10 magnification. Scale bar = 400 μm.
