AI Article Synopsis

  • Silk-elastin is a new recombinant protein polymer that combines silk and elastin to promote wound healing through a self-assembling process from liquid to gel.
  • Researchers developed a silk-elastin sponge to address application challenges faced with the aqueous solution in clinical settings.
  • The study found that the silk-elastin sponge effectively promotes granulation tissue formation just like the liquid version, as it dissolves in wound exudate to form a beneficial gel containing cytokines.

Article Abstract

Silk-elastin is a recombinant protein polymer with repeating units of silk and elastin blocks. This novel wound healing promoting material has the ability to self-assemble from a liquid to a gel. We have already reported that an aqueous solution of silk-elastin has the potential to accelerate wound healing; however, there are several problems in applying silk-elastin in the clinical setting. To solve these problems, we developed a silk-elastin sponge that is easy to use in the clinical setting. In the present study, we examined whether the wound healing effect of the silk-elastin sponge is equal to the aqueous solution of silk-elastin in vivo. The granulation tissue formation promoting effect of the silk-elastin sponge was equal to that of the aqueous solution the silk-elastin, as after application to the wound surface, the sponge was absorbed and dissolved by the exudate. At body temperature the silk-elastin then formed temperature gel. The silk-elastin gel that was obtained contained abundant cytokines from the exudate. We believe that silk-elastin sponge can be applied to various wounds that are difficult to treat with the aqueous solution.

Introductions: Silk elastin, a recombinant protein with repeats of elastin and silk fibroin, possesses a self-gelling ability and is a potential wound dressing material. The aim of this study is to elucidate the mechanism of the wound healing-promoting effect of silk elastin by comparing its in vivo behavior in a mouse wound model with that of a collagen sponge.

Methods: Skin defects (8 mm in diameter) were created on the backs of C57BL/6J and BKS.

A silk elastin-like protein (SELP) is an artificial compound with silk fibroin-like and elastin-like tandem repeats. The objective of this study is to evaluate the influence of SELP on the polarization of human monocytoma cell line (THP-1)-derived macrophages. When the macrophages of inflammation-type (M1) were cultured with different concentrations of SELP solution, the secretion of a pro-inflammatory cytokine, tumor necrotizing factor (TNF) -α was significantly suppressed at the higher concentrations.

Background: Bronchopleural fistula (BPF) is a critical complication that may progress to pneumonia and empyema, but optimal treatment remains uncertain. Our purpose was to develop a novel material for bronchial occlusion that can be used to treat BPF by blocking airflow and promoting wound healing.

Methods: Sponges were prepared in concentrations of 25, 40, and 50 mg/dL of silk-elastin by hydrophobic processing.
