Extracellular environment can be considered as urban because of the density that cells pack against one another. Physiological as well as molecular requirements necessitate such a lifestyle.
This illustration represents a view on extracellular life, showing how some cell types can associate into granules whilst others, such as immune cells, can roam throughout this environment. Cellular crowding is completely normal and a requirement of life for multicellular organisms.
