VILLARREAL-GOMEZ, Luis Jesús et al. Biocompatibility Evaluation of Electrospun Scaffolds of Poly (L-Lactide) with Pure and Grafted Hydroxyapatite. J. Mex. Chem. Soc [online]. 2014, vol.58, n.4, pp.435-443. ISSN 1870-249X.

The objective of this work was to evaluate the biocompatibility of scaffolds of poly(L-lactide) with pure and grafted hydroxyapatite, at various concentrations of reinforcement. The biocompatibility tests were carried out in vivo in Wistar rats by implanting the material into the sub-cutaneous and muscle tissues from 1 to 14 weeks and evaluating the surrounding tissue stained with hematoxylin-eosin. For in vitro assays, MTT and neutral red assay were used to evaluate any cytotoxicity in Mioblast Muscle C2C12 Cells (ATCC® CRL-1772^TM) and Bovine Coronary Artery Endothelial Cells (BCAEC); Escherichia coli and Staphylococcus aureus were used to evaluate bacterial adhesion. All variants of scaffolds provoked a mild inflammatory response, without showing necrosis. No evidence of cytotoxicity was presented in cell viability tests and good bacterial cell adhesion was visualized for all of the materials studied.
