A purified Glycosaminoglycans (GAGs) extract from L. tessellatus eggs was enzyme-hydrolyzed and then fractionated with DEAE-Sepharose column chromatography. The fractions were subsequently subjected to skin regeneration effects analysis against skin fibroblast (CCD-986sk) cell lines. Fraction 3 is evidently to have tyrosinase inhibition activity by 20.1% at concentration of 50mg/mL. DOPA oxidation assay, collagenase inhibition activity assay, fibroblast proliferation assay, and production of type I C-peptide assays were done to further proof the skin regeneration effect of GAGs fractions. Results revealed that fraction 3 has effective skin regeneration activities at a concentration of 200mg/mL.

Deep dermal and full-thickness burns often result in scar sequelae such as contractures, hypertrophy, pain and itching following split-thickness skin grafting. Dermal substitutes are currently employed alongside split-thickness skin grafting to enhance clinical outcomes, though their indications remain a subject of ongoing debate. This systematic review aims to clarify the indications for the application of dermal substitutes in burn patients, in both acute and reconstructive settings.

Peripheral nerve injury poses a significant challenge to the nervous system's regenerative capacity. We previously described a novel approach to construct a chitosan/silk fibroin nerve graft with skin-derived precursor-induced Schwann cells (SKP-SCs). This graft has been shown to promote sciatic nerve regeneration and functional restoration to a level comparable to that achieved by autologous nerve grafts, as evidenced by behavioral, histological, and electrophysiological assessments.

Clinically, abnormal or delayed wound healing leads to functional disorders and disfiguring scars. A well-vascularized environment and an anti-inflammatory immune state are crucial during the healing process. Molybdenum (Mo) is an essential element for the human body in modulating metabolism, immune function and tissue repair.

A 54-year-old female with myelodysplastic syndrome on chemotherapy presented with 10 days of periocular erythema and edema worsening on oral antibiotics. Computed Tomography scan showed periorbital soft tissue swelling without postseptal extension or abscess. Intravenous broad-spectrum antibiotics were administered.

In this study, we designed a fusion protein, rhCR, by combining human collagen with the self-assembling peptide RADA-16 using genetic engineering technology. The rhCR protein was successfully expressed in . The rhCR can self-assemble into a three-dimensional nanofiber network under physiological conditions.
