The process that a developing single cell undergoes special changes in shape and function and establishes characteristics that other cells do not have is called differentiation. Usually in the early stage of embryonic development, it has the ability to differentiate into several organs and tissues in an embryonic domain (multi-differentiation ability), but with development, the differentiation ability will be limited. In addition, it is also found that sometimes the development law of an embryonic domain has been determined before the morphological or functional changes, which is called decisive differentiation. The study of morphological and biochemical phenomena in the process of differentiation shows that there are tissue-specific genes (luxury genes) in differentiated cells, and they can also synthesize enzymes and structural proteins unique to the tissue.

The degree of similarity between tumor cells and cells of source organs, well-differentiated cells have highly specialized characteristics, clear organizational structure and easy identification. Poorly differentiated cells are unclear and difficult to identify. This tumor grading method has the value of predicting prognosis, and poorly differentiated tumors are easy to metastasize and have a short survival period.
