Histological tissue processing is a critical aspect of biomedical research, playing a pivotal role in unlocking the mysteries of human health and disease. At Visikol, the importance of histological tissue processing is not just recognized but meticulously executed with a blend of expertise and cutting-edge technology, propelling scientific discovery to new heights.
The Basics of Histological Tissue Processing
Histological tissue processing is the series of steps that transform biological tissues into thin, transparent slices suitable for microscopic examination. This process is indispensable for researchers and clinicians seeking to understand the cellular and molecular details of tissues, aiding in the diagnosis and treatment of various diseases.
Key Steps in Histological Tissue Processing
- Fixation: Formalin fixation stabilizes the three-dimensional structure of tissues by cross-linking proteins. Without fixation, tissues would undergo autolysis, a process where endogenous enzymes within the cells start breaking down cellular components. Additionally, the risk of putrefaction increases, leading to bacterial decomposition of tissues. Formalin fixation arrests these processes, allowing researchers to study tissues in a state that closely resembles in vivo conditions.
- Dehydration: The removal of all free water is crucial for embedding in nonaqueous medium such as paraffin or celloidin. Gradual dehydration with a series of alcohol solutions is important for successful processing. If the dehydration step is incomplete, the tissue will be soft and mushy. This will cause the subsequent steps to improperly achieve what they are intended for. Dehydration steps are generally where issues with processing lie. Overhydration is also a concern because molecular bound water needs to keep the cellular shape and the tissue will be brittle and difficult to work with.
- Clearing: To enhance transparency, the tissue is run through multiple rounds of a clearing reagent, which replaces the dehydrated alcohol. Clearing is vital for optimal visualization under a microscope because it makes the tissue receptive to infiltration. It is very important to choose a clearing agent that is miscible with the infiltration medium.
- Infiltration and Embedding: Tissues are infiltrated with a supporting medium like paraffin wax, creating a solid block. During embedding, the orientation at which the tissue is placed in the paraffin is also important. At any given angle, different structures will be shown depending on what is being looked for.
- Sectioning: Precision is paramount during sectioning, as thin slices enable detailed microscopic examination. Modern techniques, like microtomy, ensure consistency in section thickness.
- Staining: Staining provides contrast, highlighting specific cellular structures or molecules. Hematoxylin and eosin (H&E) staining is a classic method, but specialized stains may be employed based on research objectives.
