Isotropic 3D electron microscopy reference data of mouse choroid plexus (jrc_choroid-plexus-2)
Mouse choroid plexus epithelial cells, a primary source of the growth factor conic hedgehog in embryonic mouse brain. Here we present a typical 3D FIB-SEM data set of mouse choroid plexus at 8-nm isotropic voxel sampling. It reveals accumulation of multivesicular bodies near the epithelial cell ventricular surface.
Sample: Mouse choroid plexus
Protocol: Postfixed in 1.0% osmium tetroxide in 0.1M cacodylate buffer (pH 7.4) for 1 hour at room temperature. Following postfixation, the samples were rinsed with buffer, dehydrated through a graded series of ethanol, and embedded in durcupan.
Contributions: Sample provided by Michael Coulter & Christopher Walsh (HHMI/Harvard), prepared for imaging by Song Pang (HHMI/Janelia), with imaging by Song Pang (HHMI/Janelia) and C. Shan Xu (HHMI/Janelia), and post-processing by C. Shan Xu (HHMI/Janelia).
