Periostin plays a critical role in the development of cardiac valves and in degenerative valvular heart disease.While periostin usually is localized to the subendothelial layer in healthy heart valves, its levels are highly increased in infiltrated inflammatory cells and myofibroblasts in angiogenic areas in atherosclerotic and rheumatic valvular heart disease in humans.
The wound is initially cleaned, debrided and observed, typically 4 or 5 days before closure. The wound is purposely left open. Examples: healing of wounds by use of tissue grafts. If the wound edges are not reapproximated immediately, delayed primary wound healing transpires. This type of healing may be desired in the case of contaminated wounds.
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response , the proliferation of cells and tissues that initiate healing , and the final remodeling .
Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.
Biosignaling influences protein function, [6] chromatin condensation, [7] and protein-half life. [8] The biostructural roles of isopeptide bonds include blood clotting [ 9 ] (for wound healing), extracellular matrix upkeep, [ 10 ] the apoptosis pathway , [ 10 ] modifying micro-tubules , [ 11 ] and forming pathogenic pili [ 12 ] in bacteria.
Gelsolin is a cytoplasmic, calcium-regulated, actin-modulating protein that binds to the barbed ends of actin filaments, preventing monomer exchange (end-blocking or capping). [19] It can promote nucleation (the assembly of monomers into filaments), as well as sever existing filaments. In addition, this protein binds with high affinity to ...

Systemin is a plant peptide hormone involved in the wound response in the family Solanaceae. It was the first plant hormone that was proven to be a peptide having been isolated from tomato leaves in 1991 by a group led by Clarence A. Ryan. Since then, other peptides with similar functions have been identified in tomato and outside of the ...
