What is granulation tissue?

Granulation describes the look of tissue that is healing after an injury. Without a microscope, granulation tissue usually looks red or pink and it often feels soft to the touch. When examined under a microscope, granulation tissue is made up of many small blood vessels surrounded by a combination of cells from the immune system. These cells are called inflammatory cells.

The inflammatory cells help remove the injured tissue and build new healthy tissue. The small blood vessels bring nutrients and other support. Granulation tissue can be seen anywhere in the body with an injury. It is very common to see granulation tissue under a special kind of injury called an ulcer.
