Abstract
- We have developed a method to functionalize polystyrene (PS) cell culture plates with hydroxyapatite (HAp) via protein adsorption layers such as human serum albumin (HSA) in simulated body fluids (SBFs). In order to investigate the versatility the method, in this study the effect of protein adsorption layers on HAp deposition on PS plate surfaces in SBF was evaluated. Pretreatments with alternate soaking process (ASP) using solutions containing calcium ions and phosphate ions followed by incubation with SBF for 24 h resulted in HAp deposition on PS plates with adsorption layers of HSA, type I collagen, hen egg white lysozyme, and poly L-glutamic acid, an acidic protein analogue: the deposition behaviors were correlated with adsorption ability and charge state of proteins. We also demonstrated that commercially available tissue culture-treated PS (TCPS) were directly coated with bone-like HAp using the same ASP and SBF processes. Human mesenchymal stem cells adhered and stretched on the HAp-coated TCPS plates in a similar manner to the case of the HAp-coated PS plates prepared via HSA adsorption layers. The results indicate that the present methods are useful for preparing bone-like HAp-coated cell culture plates that can be utilized function of adsorbed proteins and that are obtainable conveniently and at low-cost.
