TEM image of epon section of a freeze-substituted mouse retina illustrating the unusual distribution of heterochromatin in rod receptor nuclei where the compact heterochromatin is centrally located. H...

Cultured retinal pigment epithelial cells immunofluorescently labeled for transferrin receptor (TfnR) (green) and nucleus (blue). The cells were fixed in 2% PFA and 0.5% Triton X-100 for 2 minutes fo...

Cultured retinal pigment epithelial cells immunofluorescently labeled for clathrin (green) and nucleus (blue). The cells were fixed in 2% PFA and 0.5% Triton X-100 for 2 minutes followed by post-fixa...

Dome-stage Zebrafish embryo. The animal pole is at the bottom of the image. The yolk syncytial layer shows two tiers of nuclei. As the sequence begins, the yolk syncytial layer narrows. The view then ...

4D data set of yolk syncytial layer nuclear movements. Movie shows z-series stacks sequentially through time. Numbers label individual nuclei so they can be tracked in 3D space at each time point. Vi...

Collagen fibrils and mineralization in the external layer of Fundulus heteroclitus scale. The external layer is the second of three layers closest to the dermis of an elasmoid. It is composed of thin ...
