Tissue processing is a crucial step in histological techniques that involves the preparation of tissue samples for microscopic examination. It encompasses several stages, including fixation, dehydration, clearing, and infiltration.

Fixation: This initial step involves preserving the tissue sample by preventing decay and maintaining its structural integrity. Common fixatives include formalin and paraformaldehyde.

Dehydration:

After fixation, the tissue is dehydrated to remove water content. This is typically done using a series of alcohol solutions with increasing concentrations.

Clearing:

Once the tissue is dehydrated, it needs to be cleared to remove the alcohol and make it transparent. This is achieved by using a substance such as xylene or toluene.

Infiltration:

Infiltration involves impregnating the tissue with a medium that will harden and provide support for sectioning. This is usually done using paraffin wax or resin.

Understanding tissue processing techniques is essential for histologists as it ensures the preservation of tissue morphology and cellular structures, allowing for accurate analysis and interpretation of histological slides.
