Lumican is a dermatan sulfate proteoglycan highly expressed in connective tissue and has the ability to regulate collagen fibril assembly. Previous studies have shown that lumican is involved in wound healing, but the precise effects of lumican on reepithelialization and wound contraction, the two pivotal aspects of skin wound healing, have not been investigated. Here we explored the roles of l...

Skin wound healing is a complex process requiring the coordinated, temporal orchestration of numerous cell types and biological processes to regenerate damaged tissue. Previous work has demonstrated that a functional β-adrenergic receptor autocrine/paracrine network exists in skin, but the role of β2-adrenergic receptor (β2AR) in wound healing is unknown. A range of in vitro (single-cell migrat...

Wound healing is an inherent feature of any multicellular organism and recent years have brought about a huge amount of data regarding regular and abnormal tissue repair. Despite the accumulated knowledge, modulation of wound healing is still a major biomedical challenge, especially in advanced ages. In order to collect and systematically organize what we know about the key players in wound hea...

Current dermal regenerative scafolds provide wound coverage, and structural support and guidance for tissue repair, but usually lack enough bio-signals needed for speeding up skin cell growth, migration, wound closure, and skin regeneration. In this study, an androgen receptor (AR) inhibitor called ASC-J9 is used to demonstrate the concept and feasibility of fabricating drug-loaded scafolds via...

Skin wound healing has been the subject of extensive studies and various drugs have been used in an attempt to improve wound healing. There are conflicting data regarding the effects of L-arginine, the substrate of nitric oxide, on wound healing. We examined the 1-week rate of cutaneous wound healing and collagen deposition in three groups of rats who received a (1) L-arginine (2% in drinking w...

INTRODUCTION As the take rate of cultured epidermal autografts in burn wound treatment is variable, widely expanded meshed auto skin grafts are often used in combination with cultured epidermal autograft to increase the take rate and achieve definitive wound coverage. However, a long time (3-4 weeks) required to prepare a cultured epidermis sheet is a disadvantage. Allogeneic cultured epidermis...

This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the ...

Background:Honey has been shown to accelerate wound healing, which is especially important in the management of patients with full-thickness wounds of skin in dermatologic surgeries. Objective: To evaluate the effects of honey in accelerating healing of full-thickness skin wounds in mice. Methods: Two groups of male NMRI mice (n=12) were subjected to full-thickness skin wounds under general ane...

Electrical measurements from wounded skin were made first in the nineteenth century by the great German physiologist Emile Du Bois Reymond. The significance of these wound currents in driving wound healing has only recently been fully appreciated. The existence and measurement of injury currents along with the underlying ionic basis for electrical signals, which is associated with wounds to ski...
