“…Surface free energy is increasingly often used as a measure of adhesive properties [40]. This is why the estimation of the solid surface free energy of the constituents from contact angle measurements can be useful to predict a work of adhesion and thus tailor new polymer-based composites [42]. For that purpose, five reference liquids with different surface energies were used.…”

“…5 Contact angles of single fibers are generally deduced from the pull-out force required to draw out the fiber of liquid (tensiometry). 29 The measurement took place in a K14 analyzer (Kru¨ss, Germany). The fiber was glued to a small wire hook, immersed in water to a depth of 1.2 mm.…”

The aim of this study was to evaluate an embroidered polycaprolactone-co-lactide (trade name PCL) scaffold for the application in bone tissue engineering. The surface of the PCL scaffolds was hydrolyzed with NaOH and coated with collagen I (coll I) and chondroitin sulfate (CS). It was investigated if a change of the surface properties and the application of coll I and CS could promote cell adhesion, proliferation, and osteogenic differentiation of human mesenchymal stem cells (hMSC). The porosity (80%) and pore size (0.2-1 mm) of the scaffold could be controlled by embroidery technique and should be suitable for bone ingrowth. The treatment with NaOH made the polymer surface more hydrophilic (water contact angle dropped to 25%), enhanced the coll I adsorption (up to 15%) and the cell attachment (two times). The coll I coated scaffold improved cell attachment and proliferation (three times). CS, as part of the artificial matrix, could induce the osteogenic differentiation of hMSC without other differentiation additives. The investigated scaffolds could act not just as temporary matrix for cell migration, proliferation, and differentiation in bone tissue engineering but also have a great potential as bioartificial bone substitute.
