Therefore, it is essential to understand the fundamental mechanisms and establish effective strategies to inhibit aberrant scar formation. in the formation of granulation tissue and in the construction of a complete circulatory system. Migrating proliferated ﬁbroblasts and macrophages, new blood vessels, and embedded collagen matrix and hyaluronic acid constitute the granulation tis-sue. Through the remodeling process, the cells gradually diminish, and a scar eventually manifests. Scar tissue can change for up to two years after its formation.

granulation tissue formation; the third and final phase of wound healing is dominated by massive biosynthesis and re-structuring of the ECM. The following discussion pertains to the three phases of tissue remodeling, with the objective of illustrating the intimate participation of ECM in all three stages of wound repair. Inflammatory stage Hypertrophic scars are pathological scars that result from abnormal responses to trauma, and could cause serious functional and cosmetic disability. To date, no optimal treatment method has been established. A variety of cell types are involved in hypertrophic scar formation after wound healing, but the underlying molecular mechanisms and cellular origins of hypertrophic scars are not fully During the proliferative phase new tissue and an extra cellular matrix to support tissue repair are laid down. During the remodelling stage, the rapidly laid down tissue is altered to more closely mimic surrounding, mature tissues. The wound healing process can be interrupted, leading to the formation of chronic wounds or the development of Scars are formed from wounds, burns, surgeries, accidents, stretch marks and skin diseases. Scars heal differently based upon the type of wound and individual factors that determine the size and look of the scar.

Cells from the edges of the wound move across the opening to close the wound in a process called epithelialization. Maturation.

The remodelling stage is definitely the longest of the three stages. This stage’s duration will depend on the type of wound. It can last from a couple of weeks to a couple of years. During this stage, the scar will start to fade and disappear.

Granulation tissue is highly vascularized connective tissue composed of newly formed capillaries, proliferating fibroblasts and residual inflammatory cells. 9.

Once the deficit has been filled with granulation tissue, the wound edges or margins will begin to contract until the wound bed is covered with new epithelium and resulting in the presence of a scar. Collagen buildup in the granulation tissue leads to the formation of a scar.
