In the early days, tissue processing would have been carried out by hand, but this was superseded by the introduction of the automated tissue processor around the middle of the 20th century. DEFINITION : Tissue processing: The aim of tissue processing is to embed the tissue in a solid medium firm enough to support the tissue and give it sufficient rigidity to enable thin sections to be cut, and yet soft enough not to damage the knife or tissue. This describes the steps required to take animal and human tissues from fixation to the state where it is completely infiltrated with a suitable wax i.e. Definition Tissue processing is defined as the process of preparing the tissue by embedding it in a solid medium that is firm enough to support it and give sufficient rigidity to enable thin sections to be cut and yet soft enough to enable the knife to cut the sections with little damage to the knife or the tissue Stages of tissue processing 1.
