Digital light processing (DLP) bioprinting has revolutionized tissue engineering by offering unprecedented speed and precision. However, its full biomedical potential is hindered by the scarcity of cell-laden bioinks that combine excellent printability with superior bioactivity. In this study, we introduce a novel cell-laden collagen-based bioink optimized for precise DLP bioprinting and diabetic wound regeneration.

Stroke patients are susceptible to malnutrition as a result of dysphagia, neurological impairments, and altered levels of consciousness. The nutritional status of individuals post-stroke is a critical determinant influencing the efficacy of rehabilitation outcomes. Therefore, there is great interest in the possible role of nutrients in promoting recovery after stroke.

Full-thickness wounds are severe cutaneous damages with destroyed self-healing function, which need efficient clinical interventions. Inspired by the hierarchical structure of natural skin, we have for the first time developed a biomimetic tri-layered artificial skin (TLAS) comprising silica gel-collagen membrane-collagen porous scaffold for enhanced full-thickness wound healing. The TLAS with the thickness of 3-7 mm displays a hierarchical nanostructure consisting of the top homogeneous silica gel film, the middle compact collagen membrane, and the bottom porous collagen scaffold, exquisitely mimicking the epidermis, basement membrane and dermis of natural skin, respectively.

Herein, a choline chloride-based ionic liquid analogue (ILA) macroscale superlubricant is first reported by tuning down strong hydrogen bonding in the ILA via introducing 2-10 wt % water, with a high load of 160 MPa and a low coefficient of friction of 0.006-0.

Sunburn is one of the most common skin lesions caused by excessive UV exposure, and its incidence is highly correlated with the risks of skin cancer. A variety of drugs including corticosteroids and NSAIDs have been developed to treat acute sunburn, however, they have raised severe concerns such as poor healing efficacy and long recovery time. We have for the first time extracted non-denatured type I collagen from yak hide, which displays a canonical triple helical structure with melting temperature of 42.

Background: Cytoskeletal elements play key roles in cell morphology, cell division, cell mobility, and DNA partitioning in all domains of life. The IF-like protein FilP was discovered in Streptomyces coelicolor, and it was found to perform a structurally important cytoskeletal role by providing direct mechanical support for the cells.
Objective: This work investigated the factors influencing FilP polymerization under a variety of conditions.
Background: Collagen has been widely utilized in tissue engineering, regenerative medicine and cosmetics. Collagen of low concentrations is frequently applied to reduce the production cost, while it may result in the loss of triple helical structure and bioactivity. CD and NMR techniques have enhanced our understanding of collagen triple helix, while they require high concentrations of collagen samples.

"Ecological resilience" has been proposed to describe the capacity of natural systems to absorb external perturbation and reorganize while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks. However, the mere application of ecological resilience in theoretical research and the lack of quantitative approaches present considerable obstacles for predicting critical transitions and understanding their mechanisms.

Collagen with a single amino acid substitution is the main cause of a plethora of heritable disorders such as Osteogenesis Imperfecta and Ehlers-Danlos syndrome. Though significant advances have been achieved in the development of protein assays, it remains very challenging to distinguish a protein with a single amino acid mutation from the wild-type protein. A novel fluorescent self-quenching assay has been constructed to detect target collagen peptides with a single amino acid mutation using two probe peptides.
