“…Gelatin-based gel contained a dense network of short and thick fibers organized in sheets, along with heterogeneous voids. Additionally, the morphology of BG gel showed a low porosity microstructure with visibly very small pores, similar to previous gelatins extracted from other sources such as cuttlefish skin gelatin (Jridi et al, 2015), commercial acid-soluble collagen skin (Potorac, Popa, Maier, Lisa, & Verestiuc, 2012) and horse mackerel bones (Jansson, Haegerstrand, & Kratz, 2001). Wang et al (2014), reported in their study, that the collagen gel extracted from Amur sturgeon skin, showed an irregular dense fibrillar microstructure with high interconnection network and massive and porous nature.…”

The present study aims to characterize black-barred (Hemiramphus far) skin gelatin (BG) gel enriched or not with its hydrolysate (BGH) in terms of their rheological and micro-structural properties, as well as to evaluate their effect on smooth hound fillet quality during chilled storage. The results of the rheological properties showed that peptides addition influenced elastic and loss modulus as observed from temperature sweep. Based on the microstructure, BG gel had a fine network with small voids that were filled by the presence of BGH peptides. On the other hand, when used as coating agents for smooth hound fillets, BG and BG-BGH showed that, in comparison to control group, fish spoilage was significantly delayed in coated samples. In fact, after 8 days of storage, samples coated with BG and BG+BGH showed the lowest weight loss levels, and preserved their initial water activity (a w) values. In addition, fillet coating was able to significantly reduce TVB-N content and oxidation process, as reflected by the low malondialdehyde and carbonyl contents. Furthermore, compared to the control group, all the treatments were found to reduce the degree of microbial deterioration of the fillets, leading to low the free amino acids and nucleotides contents in wrapped fish samples. Therefore, gelatin coating helps to prevent fish fillets from deterioration and oxidation processes.

This review provides a report on properties and recent advances in the application of collagen in cosmetics. Collagen is a structural protein found in animal organisms where it provides for the fundamental structural support. Most commonly it is extracted from mammalian and fish skin. Collagen has attracted significant academic interest as well as the attention of the cosmetic industry due to its interesting properties that include being a natural humectant and moisturizer for the skin. This review paper covers the biosynthesis of collagen, the sources of collagen used in the cosmetic industry, and the role played by this protein in cosmetics. Future aspects regarding applications of collagen-based materials in cosmetics have also been mentioned.

“…Wound healing is a complex procedure, involving several distinct stages and a series of cells and cytokines [ 17 ]. To facilitate the wound healing process, a range of natural biomaterials have been developed, namely cellulose, alginate, collagen and chitin, hyaluronic acids, and others [ 18 – 26 ]. Because of the favorable characteristics of natural biomaterials, such as biocompatibility, biodegradation, low-toxicity or nontoxicity, mechanical stability, high moisture content, and high availability, the use of natural biomaterials is attractive for advanced wound management.…”

Bioprinting of skin constructs for wound healing

et al. 2018

View full text Add to dashboard Cite

Extensive burns and full-thickness skin wounds are difficult to repair. Autologous split-thickness skin graft (ASSG) is still used as the gold standard in the clinic. However, the shortage of donor skin tissues is a serious problem. A potential solution to this problem is to fabricate skin constructs using biomaterial scaffolds with or without cells. Bioprinting is being applied to address the need for skin tissues suitable for transplantation, and can lead to the development of skin equivalents for wound healing therapy. Here, we summarize strategies of bioprinting and review current advances of bioprinting of skin constructs. There will be challenges on the way of 3D bioprinting for skin regeneration, but we still believe bioprinting will be potential skills for wounds healing in the foreseeable future.
