Abstract
The chronification of ulcers or sores may result in a dramatic outcome such as amputation. Currently, the search for plant based treatments of various diseases/disorders, including complicated ones, is getting the attention of researchers worldwide. The soluble latex protein fraction (CpLP) obtained from Calotropis procera (Apocynaceae) was previously demonstrated to accelerate wound healing by topical application or when incorporated in a polyvinyl alcohol biomembrane (BioMemCpLP). Here, in vitro assays were performed to investigate and characterize the biocompatibility and bioactivity of latex proteins dressing. Macrophages (RAW 264.7), fibroblasts (L929) and keratinocytes (HaCaT) cell lines were used to evaluate the effect of CpLP. These cell lines were exposed to concentrations of CpLP comparable to those found in BioMemCpLP during 24-72 h. The cytotoxicity, proliferation, release of wound healing mediators (TGF-β, VEGF, IL-10, IL-6, IL-1β, TNF-α and NO) and migration of cells (E-cadherin and β-catenin) incubated with CpLP was assessed and the cell adhesion to BioMemCpLP as well. The results showed that CpLP has no cytotoxic effects. It induced a suitable balance between pro- and anti-inflammatory mediators, enhanced proliferation and re-epithelialization in all cell lines, but the intensity of each effect was different at various doses in all cell strains. The BioMemCpLP stimulated cell adhesion to PVA substrate. The CpLP-PVA based biomembrane can be a good option for healing of different wounds.
