Topography-Guided Proliferation: Distinct Surface Microtopography Increases Proliferation of Chondrocytes In Vitro

Abstract

Chondrocyte-based cartilage repair techniques require control of articular chondrocyte expansion ex vivo. Articular chondrocytes have limited availability, and prolonged culturing to obtain a cell number sufficient for clinical use often results in phenotypic alterations and increased costs. In this study, we applied a screening library consisting of micrometer-sized topographical features, termed biosurface structure array (BSSA), to identify specific topographical microstructures affecting the proliferation of human chondrocytes in passage 1 (P1) or 2 (P2). The BSSA library comprised 10 patterns and 16 combinations of pillar size (X) and interpillar gap size (Y). Specific microstructures significantly increased the chondrocytes' proliferative responsiveness in term of patterns, X and Y for P2 compared with P1. The P1 and P2 chondrocytes responded independently to similar patterns after 4 days of culturing, whereas only chondrocytes at P2 responded to specific microstructures with Y = 1 μm and X = 2, 4 μm by a 2.3- and 4.4-fold increased proliferation, respectively. In conclusion, these findings indicate that specific surface topographies promote chondrocyte proliferation and may, indeed, be a tool to control the behavior of chondrocytes in vitro.
