Histochemical staining of lymphatic anchoring filaments.

Lymphatic anchoring filaments are stained by means of histochemical methods that demonstrate disulfide-groups. Thiosulfation of sections either followed by aldehyde-fuchsin staining or by Alcian Blue +0.8 M MgCl2 staining has been used. Lymphatic anchoring filaments display striking fine structural similarities to "elastic fiber microfibrils" and both kinds of fibers are characterized by disulfide content.
