This is recognised as the first published record of the word ‘cell’. Early efforts to study pathology were often stymied by religious prohibitions against autopsies, but these gradually relaxed during the late Middle Ages, allowing autopsies to determine the cause of death, the basis for pathology. Histology is defined as the scientific study of the microscopic structure (microanatomy) of cells and tissues. Marie François Bichat, a French pathologist (1771-1802) is considered, by some authors, to be the founder of Animal Histology as he introduced in Science the definition of tissue.

UNMC Department of Pathology and Microbiology History. Yale School of Medicine was founded in 1810. His discovery established how the oxygen breathed in enters the blood stream and serves the body. This process is called immunohistochemistry, or when the stain is a fluorescent molecule, immunofluorescence. As the biomedical research industry evolves, so too does histological analysis, as it continually responds to new scientific and medical challenges for a growing (and aging) worldwide population. The Department of Pathology at Yale was established in 1867, as the Department of Pathology and Microscopy. For tissues to be cut in a frozen state, tissues are placed in a water-based embedding medium.
