Histology laboratories take a fundamental part in medical and biological research. Its importance is due to the possibility of studying cells and tissues of plants and animals. Histological studies may be conducted using tissue culture, where live human or animal cells are isolated and maintained in an artificial environment for various research projects. There are several steps to follow when it comes to preparing a sample, including fixing, processing, embedding, sectioning and staining.
In histology labs, a very common procedure is the tissue sampling, processing and staining. This is a very common and delicate process that needs to be done in the proper way, in order to not compromise the lab results. Tissue processing is about the diffusion of substances into and out of porous tissues. The diffusion process happens when you process reagents to equal concentrations inside and outside tissue blocks.
