Abstract

Previously it was documented that transgenic flax plants, which contained an increased level of polyphenolic compounds, significantly improved healing of skin wounds lesions. In order to recognize mechanisms of beneficial action of transgenic flax fabrics on wound healing, in the present study the impact of flax fabric pieces/cuts from three types of transgenic flax on normal human dermal fibroblasts primary culture (NHDF) was investigated. NHDF cell cultures were exposed for 48 h to specific area of flax fabric cuts, made from M50, B 14 and M50+B14 (intertwined fibers of M and B), or parallely, extracts from fibers of the tested flax materials to cell culture medium. Cultures were inspected for cell viability, proliferation, cell cycle changes and for their resistance to oxidative stress (consecutive addition of H₂,O₂, to harvested cell cultures). None of the tested flax fabrics were cytotoxic to fibroblast cultures and also did not increase significantly a frequency of apoptotic cells in cultures. In the comet assay, the tested flax fabrics revealed significant protective effect on DNA damage ciused by addition of H₂0₂ to the cultures at the end of incubation time. Fabrics from transgenic flax significantly enhanced fibroblasts proliferation in vitro estimated with the SRB test. Flow cytometric analysis revealed higher frequency of cells in the S phase, in the presence of transgenic flax fabrics. Fabrics from B14 and M50+B14 flax are the most potent activators of NHDF cells in applied in vityo tests, hence they could be recommended for elaboration of new type bandage, able to improve skin wound healing.
