Abstract

Sections of undecalcified human fetuses, fixed in formaldehyde, embedded in the epoxy resin Biodur E 12 and cut on a diamond-wire saw were stained according to a slight modification of the method described by Laczkó and Lévai. The sections were immersed in a methylene blue/azure II solution at 90 C for at least 3 min and counterstained with a basic fuchsin solution at the same temperature. Differential staining was as follows: bone stained pinkish; cartilage, violet; collagen fibers, blue-violet; elastic fibers, red and muscle fibers, green-blue. Most other tissues were stained blue-violet against the transparent background of the embedding epoxy resin. Thanks to the distinct and differential staining of each tissue, contrast is sufficient for black and white as well as for color photography.
