What happens during the proliferative phase of a wound?
Epithelialisation, fibroplasia and angiogenesis occur during the proliferative phase. Meanwhile, granulation tissue forms and the wound begins to contract. Finally, during the maturation phase, collagen forms tight cross-links to other collagen and with protein molecules, increasing the tensile strength of the scar.
Why is DBC important?
DBC may be an important material to control and regulate the pH of the wound during the healing process. As already mentioned, the pH is an important parameter for wound healing and the control of the pH until neutral constitutes an important positive effect of DBC on wound healing.

Formation of granulation tissue is a central event during the proliferative phase. Inflammatory cells, fibroblasts, and neovasculature in a matrix of fibronectin, collagen, glycosaminoglycans, and proteoglycans comprise the granulation tissue. Granulation tissue formation occurs 3–5 days following injury and overlaps with the preceding inflammatory phase.

Abstract
The great variety of wounds and the lack of an effective universal treatment method has resulted in high demand for modern treatment strategies. Traditional approaches are often ineffective on a variety of chronic wounds, such as venous ulcers or the diabetic foot ulcer.
1. The Healing of Acute and Chronic Wounds
Chronic wounds occur as the result of delayed and prolonged healing of the acute wounds [ 1, 2, 3 ]. The differences between acute and chronic wounds mainly lie in the biochemical environment present in the wound bed [ 4 ].
2. Current Concepts in Wound Dressings
Accurate wound valuation—including estimation of the wound size, color, type, location, and exudate level—determines the most suitable type of the wound dressing to be used [ 15 ].
3. Pro-Healing Wound Dressings
Plants play a significant role in conventional wound treatments. Widely used medical plants are rich in bioactive natural compounds with immunomodulatory properties. As a consequence, naturally derived active agents may control the inflammatory response and promote re-epithelialization and wound contraction [ 49 ].
4. Patented and Commercial Bioactive Dressings
Due to the high biomedical potential of some wound care products, more and more research units have decided to patent the method for wound dressing production. The European Patent Office holds thousands of patents covering wound dressings loaded with bioactive agents.
5. Conclusions
The presented review article focused on the recent findings regarding modifications of wound dressings that have contributed to the development of regenerative medicine. In this context, various production methods of dressing materials with improved pro-healing features were presented.
