Once collected, tissues need to be preserved to prevent degradation and maintain their morphology. The most common preservation methods include:
Fixation: Immersing tissues in chemical solutions like formalin to preserve cellular structure and prevent decomposition. Freezing: Rapidly freezing tissues using cryostats to preserve them for techniques like cryosectioning. Embedding: Enclosing tissues in paraffin wax to provide support for thin sectioning.
