Abstract:
Objective:To prepare histatin 1 (Hst 1) and D-histatin 1 (D-Hst 1) coatings on pure titanium surfaces and to evaluate their impact on the initial adhesion and spreading of mouse bone marrow mesenchymal stem cells (mBMSC).Methods:The test pieces were divided into four groups: pure titanium, piranha solution-treated, 3-aminopropyltriethoxysilane-treated, Hst 1 modified groups or D-Hst 1 modified groups, with five pieces in each group. The surface hydrophilicity of the test pieces was detected by contact angle measurement. The surface microtopography was observed using atomic force microscopy (AFM), and the surface elemental composition was analyzed by X-ray photoelectron spectroscopy (XPS). The modification of Hst 1 on the titanium surface and the early adhesion and spreading of the third-generation normal mBMSC on Hst 1/D-Hst 1 modified group were observed using confocal laser scanning microscopy (CLSM).Results:The Hst 1 modified group had better surface hydrophilicity (contact angle 51.63°±3.80°) compared to the pure titanium group (contact angle 60.36°±4.38°). AFM observations revealed shallow mechanical scratches on the surfaces of all test pieces. CLSM and XPS elemental analysis confirmed the successful modification of Hst 1 on the titanium surface. Compared with the pure titanium group, both Hst 1 and D-Hst 1 could promoted the early adhesion of mBMSC. The Hst 1 modified group promoted the spreading of mBMSC after early adhesion, while the D-Hst 1 modified group showed no statistically significant difference in promoting mBMSC spreading compared to the pure titanium group ( P>0.05). Conclusions:The modification of Hst 1/D-Hst 1 on pure titanium surfaces using Schiff base reaction is effective. It is conducive to the early adhesion and spreading of mBMSC.
