How do growth factors influence cell behavior during tissue repair?

Growth factors play a crucial role in the tissue repair process by regulating various cellular behaviors. Specifically, they actively influence the activities of cells involved in healing, including their migration to the injury site and their proliferation, which is essential for tissue regeneration. When tissues are injured, growth factors are released at the site of damage, signaling nearby cells to move toward the area to initiate repair processes. This migration is necessary to cover the wound and contribute to new tissue formation.

In addition to facilitating the movement of cells, growth factors also promote cell division and proliferation, which leads to an increase in the number of cells available to rebuild the damaged tissue. This coordinated response is crucial for effective healing and restoration of function.

The other choices do not accurately represent the primary functions of growth factors in this context. While they can have complex roles in inflammation or cellular interactions, their fundamental contribution during tissue repair centers around enhancing migration and proliferation of cells.
