Abstract:
A major technical problem in the processing of resin-embedded tissues is the adhesion of the tissue sample on glass slides for immunohistochemical labelling. We therefore established a novel protocol for processing such specimens with improved attachment of the tissue sample during resin removal (deplastification). In order to demonstrate the feasibility of the procedure we employed a panel of smooth muscle cell maturation markers. The technique makes use of a silicone glue (Elastosil E41; Wacker Chemie, München, Germany) to attach the tissue samples to the glass slides. This allows resin dissolution in xylene/2-methoxyethylacetate without detachment of the sample from the slide. Our results demonstrate successful immunohistochemical labelling with primary antibodies directed against: smooth muscle actin, smooth muscle myosin, h-caldesmon, desmin, vimentin and von Willebrand factor. In conclusion, we have established a new and successful method for resin-embedded sample adhesion on glass slides. The developed protocol is feasible for investigation of cells which are involved in intimal proliferation following stent implantation.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
