    Infrared attenuated total reflection spectroscopy was used for in situ observation of the deposition of collagen I on poly(2-hydroxyethyl methacrylate-co-methacrylic acid, 2.9%) hydrogels and subsequent attachment of laminin or fibronectin on the collagen surface. The collagen layers with attached laminin or fibronectin were stable on hydrogel surface in physiological solution. The modification with collagen and particularly with collagen and laminin or fibronectin allowed the adhesion and growth of mesenchymal stromal cells and astrocytes on the hydrogel surface.

    Infračervená reflexní spektroskopie (IR ATR) byla použita pro in situ pozorování depozice kolagenu I na poly(2-hydroxyethyl methacrylate-co-methacrylic acid, 2.9%) hydrogel a následného připojení lamininu nebo fibronektinu na povrch kolagenu. Kolagenové vrstvy s přichyceným lamininem nebo fibronektinem byly stabilní ve fyziologickém roztoku. Modifikace kolagenem a zvláště pak kolagenem s připojeným lamininem nebo fibronektinem umožnila adhezi a růst mesenchymálních stromálních buněk a astrocytů na povrchu hydrogelu.
