Abstract
In the present work, microporous membranes based on poly(ε-caprolactone) (PCL) and PCL functionalized with amine (PCL-DMAEA) or anhydride groups (PCL-MAGMA) were realized by solvent-non solvent phase inversion and proposed for use in Guided Tissue Regeneration (GTR). Nanowhiskers of hydroxyapatite (HA) were also incorporated in the polymer matrix to realize nanocomposite membranes. Scanning Electron Microscopy (SEM) showed improved interfacial adhesion with HA for functionalized polymers, and highlighted substantial differences in the porosity. A relationship between the developed porous structure of the membrane and the chemical nature of grafted groups was proposed. Compared to virgin PCL, hydrophilicity increases for functionalized PCL, while the addition of HA influences significantly the hydrophilic characteristics only in the case of virgin polymer. A significant increase of in vitro degradation rate was found for PCL-MAGMA based membranes, and at lower extent of PCL-DMAEA membranes. The novel materials were investigated regarding their potential as support for cell growth in bone repair using multipotent mesenchymal stromal cells (MSC) as a model. MSC plated onto the various membranes were analyzed in terms of adhesion, proliferation and osteogenic capacity that resulted to be related to chemical as well as porous structure. In particular, PCL-DMAEA and the relative nanocomposite membranes are the most promising in terms of cell-biomaterial interactions.

Abstract
Purpose In the framework of a project aiming to improve the properties of poly(∊-caprolactone) (PCL)-based devices, we prepared novel composites and tested their in vitro biocompatibility and osteogenic capacity on human mesenchymal stromal cells (MSC) from bone marrow. Methods We prepared two functionalized derivatives, PCL-g-MAGMA and PCL-g-DMAEA, by insertion of anhydride groups by radical grafting of maleic anhydride (MA) and glycidyl-methacrylate (GMA) molecules, and by insertion of N-(dimethylamino)ethylacrylate (DMAEA) of tertiary amines groups, respectively. In addition, in order to improve the osteo-conductive properties of the materials, we also prepared the corresponding composites containing the mineral component of bone, namely hydroxyapatite (HA). Mesenchymal stromal cells (MSC) derived from bone marrow were prepared, plated onto a number of discs obtained from these functionalized derivatives and tested in terms of adhesion and vitality (by MTT test and SEM observation), and the expression of alkaline phosphatase, the early marker of osteoblastic phenotype. Results The biological in vitro assessment of the functionalized materials, PCL-g-MAGMA and PCL-g-DMAEA, appeared promising only in part, in particular the cells exhibited very poor adhesion to PCL-g-MAGMA. On the contrary, the related composites, PCL-g-MAGMA-HA and PCL-g-DMAEA-HA clearly showed that the addition of HA greatly ameliorated the cellmaterial interaction. In particular, a surprisingly increased response characterized PCL-g-MAGMA-HA, either in terms of adhesion and vitality or in terms of alkaline phosphatase activity. Conclusions Altogether these studies showed that the addition of HA nanowhiskers resulted for all basic materials, in particular PCL-g-MAGMA, in improved cell adhesion and performance.
