Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
These cell types accelerate the healing process and prevent further complications such as hypoxia by gathering the cellular materials to reconstruct the endothelium. [19] Endothelium dysfunction is a prototypical characteristic of vascular disease, which is common in patients with autoimmune diseases such as systemic lupus erythematosus. [20]
A week after the injury, the edges of the wound are pulled together by contraction. Contraction is an important part of the healing process when damage has been extensive, and involves shrinking in size of underlying contractile connective tissue, which brings the wound margins toward one another.

Simply, Plan B is an over-the-counter (OTC) pill that contains a highly concentrated dose of hormones to block a pregnancy after unprotected P-in-V intercourse has occurred.
[28] [29] Calcium channel blockers and selective beta 1 antagonists may also improve endothelial dysfunction. [14] Life style modifications such as smoking cessation have also been shown to improve endothelial function and lower the risk of major cardiovascular events. [30]
Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis , among others. [ 2 ]
Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue.
The epithelial–mesenchymal transition (EMT) is a process by which epithelial cells lose their cell polarity and cell–cell adhesion, and gain migratory and invasive properties to become mesenchymal stem cells; these are multipotent stromal cells that can differentiate into a variety of cell types.
