Preparation of recombinant type I collagen (PF-I-80) and its functional characterization and biomedical applications in wound healing.

This study evaluates the potential applications of recombinant PF-I-80 protein in regenerative medicine and the treatment of inflammatory diseases, focusing on its effects on cell migration, differentiation, and anti-inflammatory properties. Various in vitro assays were conducted, including scratch assays, Transwell experiments, RT-PCR and Western Blot to analyze gene and protein expression related to differentiation and inflammation, and immunofluorescence staining to observe cellular changes. The results indicated that PF-I-80 significantly promoted cell migration, highlighting its potential in tissue repair and regeneration.

Antheraxanthin: Insights delving from biosynthesis to processing effects.

Antheraxanthin (CHO) is one of fat-soluble carotenoids belonging to natural pigments. Its chemical structure is based on the unsaturated polyene chain skeleton, with a hydroxy-β-ionone ring and an epoxy-β-ionone ring on each side of the skeleton. It is found in a wide range of plants and photosynthetic bacteria, and external stimuli (high temperature, drought, ozone treatment, etc.
