For my second week in the Histology lab, I will describe the processes of tissue processing, embedding, and microtomy. During this week, I processed, embedded, and cut over 100 tissues.
In my previous blog, the gross description of tissues was explained. After grossing, tissues are then put into tissue processor machines. Tissue processing consists of different chemicals entering the tissue for preservation. Tissues are then embedded into paraffin wax using the appropriate orientation. After tissues are embedded in wax and cooled, they can be cut using a microtome to create thin ribbons of tissues. These thin ribbons are then put onto slides. Continue reading
