			Granulation is a crucial process in the [[wound healing]] and [[tissue repair]] phases of the [[healing]] process. It involves the formation of new connective tissue and tiny blood vessels that form on the surfaces of a wound during the healing process. This tissue is called "granulation tissue" due to its granular appearance.

	==~~Formation~~==		==Process==
	~~The formation~~ of ~~granulation tissue is often the first sign that a~~ wound is healing. During ~~this process~~, fibroblasts ~~migrate to the site~~ of ~~the injury~~, ~~where they begin to produce~~ collagen ~~and other~~ extracellular matrix ~~proteins~~. This new tissue ~~is highly vascularized and appears red or pink because of the many new blood vessels that are formed~~.		Granulation occurs during the [[proliferative phase]] of wound healing. This phase follows the [[inflammatory phase]] and precedes the [[maturation phase]]. During granulation, fibroblasts, a type of cell, proliferate and synthesize [[collagen]], which is a key component of the extracellular matrix. This matrix provides a scaffold for new tissue formation.

	==~~Role in Wound Healing~~==		===Angiogenesis===
	~~Granulation~~ tissue ~~plays a crucial role in the~~ [[~~wound healing~~]] ~~process~~. ~~It provides~~ the ~~framework for~~ the ~~growth of~~ new ~~skin, known as epithelialization~~. The ~~tissue also helps to prevent infection by serving as a barrier against bacteria~~ and ~~other pathogens~~.		A significant aspect of granulation is [[angiogenesis]], the formation of new blood vessels. This process is essential for supplying nutrients and oxygen to the healing tissue. [[Endothelial cells]] migrate and form new capillary loops, which give granulation tissue its characteristic red, granular appearance.

			===Fibroplasia===
			[[Fibroplasia]] is another critical component of granulation. Fibroblasts produce collagen and other extracellular matrix components, which help to fill the wound and provide strength to the new tissue. The balance between collagen synthesis and degradation is crucial for proper wound healing.

	==Clinical Significance==		==Clinical Significance==
	~~In some cases, granulation~~ tissue ~~can overgrow, leading to the formation~~ of ~~[[granuloma]]~~. ~~This can occur in response to foreign bodies, certain types of infections~~, ~~or long-standing wounds. Overgrowth of~~ granulation ~~tissue can also occur in certain diseases~~, ~~such~~ as [[~~pyogenic granuloma~~]].		Granulation tissue is a positive indicator of healing. However, excessive granulation, known as "[[proud flesh]]" or "hypergranulation," can impede wound closure and may require medical intervention. Proper wound care and management are essential to promote healthy granulation and prevent complications.

	==~~Treatment==~~		==Related pages==
	Treatment of excess granulation tissue may involve the use of topical corticosteroids, silver nitrate, or surgical removal. The choice of treatment depends on the size and location of the granulation tissue, as well as the overall health of the patient.
