Description
Summary:A pivotal factor to consider in the development of biomaterials and biomaterial coatings is the inflammatory response to these materials. The insertion of implants is followed by protein adsorption and subsequent interactions with cellular components of the biological surroundings, in which macrophages play a dominant role through the production of a myriad of signaling molecules. In view of this, the aims of the present study were to evaluate (i) gross protein adsorption to, and (ii) in vitro behavior of macrophages on novel biomaterial coatings, composed of poly‐D‐lysine (PDL) or poly(allylamine hydrochloride) (PAH) and DNA, and to compare these coatings with negative (noncoated glass) and positive controls (noncoated glass + LPS‐stimulation). The results demonstrate that multilayered DNA‐coatings do not affect gross protein adsorption compared to noncoated controls. Cell culture experiments showed that the attachment to, and viability and morphology of two types of macrophages cultured on multilayered DNA‐coatings is comparable to noncoated controls. Still, macrophages repeatedly showed decreased secretion levels of the proinflammatory cytokine TNF‐α on multilayered DNA‐coatings, whereas no differences were observed in the secretion of IL‐1β, IL‐10, and TGF‐β1. Appropriate animal studies are required to elucidate if these in vitro indications have clinical effects on the inflammatory and wound healing processes around implants. © 2006 Wiley Periodicals, Inc.
