Transverse section through the neural tube of an early stage chick embryo. The brown stain shows the neurofilament in the axons of the commisural neurons (running down the sides of the neural tube) an...

Confocal micrograph of “lost” axons - chick interneurons labeled with green fluorescent protein that were transplanted from older into younger embryos. When they encounter unfamiliar territory, th...

chicken erythrocyte nuclei were allowed to decondense in a low salt high pH buffer, fixed with HCOH, centrifuged onto a carbon coated EM grid, and stained with uranyl acetate. (Spreading technique of ...

Nucleated erythrocytes from chicken were spread on water, the dispersed chromatin picked up on carbon-formvar grids, fixed with paraformaldehye, critical point dried and shadowed with platinum. Image...
