摘要: Enhancement of porcine chondrocyte growth, distribution and functions within polycaprolactone (PCL) scaffolds was attempted using alkaline hydrolysis oxygen plasma treatment. The PCL performed either before or after scaffold fabrication in the preparations pre-hydrolyzed (pre-HPCL) post-HPCL scaffolds, respectively. PCL, pre-HPCL, were subsequently plasma-treated to yield All comparatively characterized, terms surface morphology, hydrophilicity, atomic composition scanning electron microscopy, contact angle measurement X-ray photoelectron spectroscopy, interactions chondrocytes with individual assessed, cartilage-gene expression cartilaginous matrix production reverse transcription polymerase chain reaction analysis glycosaminoglycans (GAGs) assay, cell infiltration investigated by histological immunofluorescence analysis. results revealed that treatment exhibited a more prominent effect on enhancement roughness hydrophilicity than hydrolysis. subjected both treatments stimulated cells secret GAGs type II collagen. sequence also evidently played crucial role materials cultured chondrocytes. prior fabrication, followed resulting fabricated scaffold, yielded pre-HPCL homogeneous hydrophilic characteristics all over material. Consequently, could proliferate well, infiltrate most deeply ultimately produce highest amounts cartilage-specific substances throughout this scaffold.
