Article Abstract
There is a need in clinical practice for new wound healing techniques to address full thickness skin injuries, particularly in individuals with diabetes. Herein we investigated whether dermal derived matrix hydrogel (DMH) loaded with curcumin (Cur) could promote healing in diabetic rats. Sixty diabetic rats were randomly assigned into the non-treated group, DMH group, Cur group, and DMH+Cur group. According to the phases of wound healing, sampling was done on days 7, 14, and 21 for further assessments. Our results indicated that the wound contraction rate, new epidermal length and thickness, number of fibroblasts and vascular length, collagen deposition, and strength properties of the healed wounds were meaningfully increased in the treatment groups than in the non-treated group, and these changes were more obvious in the DMH+Cur ones. In addition, the expression of VEGF and IL-10 genes were meaningfully upregulated in all treatment groups compared to the non-treated group and were greater in the DMH+Cur group. This is while the number of neutrophils and expression levels of TNF-α and IL-1β genes decreased more significantly in the DMH+Cur group compared to the other groups. In conclusion, it was found that using both DMH and curcumin has a greater impact on diabetic wound healing.

Dermal fillers have gained increasing popularity for their ability to enhance facial symmetry, restore volume, and improve skin texture. However, their use in patients with cancer undergoing active chemotherapy and radiation therapy poses unique challenges, as these treatments can alter both the safety profile and efficacy of filler procedures. Chemotherapy can interfere with normal wound healing and immune responses, warranting a more cautious and individualized approach when considering dermal fillers in this population.

It is essential to develop new strategies for wound treatment and skin reconstruction, particularly by scaffolds that replicate the structure and function of native skin. A bilayer scaffold was developed using three-dimensional (3D) bioprinting, based on a uniform chitosan-based formulation for both layers, maintaining material uniformity while offering structural support and promoting cell adhesion. The upper chitosan layer, embedded with NHEK-Neo, is stiffer and mimics the epidermis, while the softer lower layer contains embedded HFFs and HFSCs, mimicking the dermis.

In recent years, the incidence of orthopedic diseases has increased significantly, while traditional treatments often face limitations such as limited efficacy and pronounced side effects. The development of nanomedicine technology provides novel strategies for orthopedic disease treatment. As an emerging two-dimensional (2D) nanomaterial, black phosphorus nanosheets (BPNS) demonstrate remarkable potential in treating orthopedic diseases due to their unique physicochemical properties, superior biocompatibility, and the fact that their degradation product-elemental phosphorus-constitutes an essential component of bone tissue.

Skin scar formation is a critical pathological process in wound healing, but its underlying regulatory mechanisms remain incompletely elucidated. By integrating analyses of Bulk-RNA seq and single-cell RNA sequencing (scRNA-seq) data, we identified that ferroptosis-related biological processes potentially play a key role in skin scar formation. Further mechanistic studies demonstrated that in human dermal fibroblast cells, the ferroptosis regulator TIMP metallopeptidase inhibitor 1 (TIMP1) significantly promotes fibroblast differentiation toward a mature phenotype through interactions with cystatin C (CST3), characterized by upregulated expression of myofibroblast differentiation markers such as α-smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF), along with enhanced cell proliferation and migration abilities.
