Final answer:
When extracellular matrix materials are added back to the cells, they contribute to tissue formation and cell communication. One example is blood clotting, where the extracellular matrix plays a crucial role.
Step-by-step explanation:
When extracellular matrix materials are added back to the cells, they contribute to the formation and maintenance of tissues by holding the cells together.
The extracellular matrix also allows cells within the tissue to communicate with each other through various signaling pathways.
One example is blood clotting, where damaged cells release tissue factor that binds with another factor in the extracellular matrix to stimulate platelet adhesion and initiate clotting factors production.
