Colorized transmission electron micrograph of a platinum replica showing the cytoskeletal organization of stubby dendritic spines in extracted hippocampal neurons after 14 DIV. Unlabeled inset shows the smaller version of the corresponding main panel with axons color-coded in purple, dendrites in yellow, and spines in cyan. Yellow box indicates the enlarged panel shown on the bottom of the image. This box shows branched actin filaments (cyan) in the spine bases associate with dendritic microtubules (red). Bar, 0.2 μm. Image corresponds to Figure 3b in Mol Biol Cell. 2010 Jan 1;21(1):165-76. The entire panel (this image) is available as CIL 40952. The uncolorized image is available as CIL 40804, and the insert is available as CIL 40810.
