Tissue Healing

Growth factors and their role in wound healing can be defined as:

• Proteins that stimulate cell growth and play a crucial role in the repair and regeneration of tissues during wound healing.

• Enzymes that break down tissue and delay the wound healing process.

• Hormones that prevent blood clotting and slow down healing.

• Vitamins that only provide nutrition but do not affect wound healing.

Major types of growth factors include which of the following?

• Epidermal, platelet-derived, and nerve growth factors

• Insulin, glucagon, and adrenaline

• Hemoglobin, myoglobin, and actin

• Collagen, elastin, and keratin

Growth factors function in each healing phase by:

• Stimulating cell proliferation, migration, and differentiation during inflammation, proliferation, and remodeling phases.

• Only providing nutrients during the inflammation phase.

• Inhibiting cell growth throughout all healing phases.

• Causing permanent tissue damage in the remodeling phase.
