Fig. 9From: Osteoblast behaviours on nanorod hydroxyapatite-grafted glass surfacesSEM images showing the adhesion of MC3T3E1 cells on the Glass (a-c) and the Glass-nHA (d-f). The cells were cultured at a density of 4 × 104 cells/mL at 37 °C, 5% CO2 in humidified atmospheres for 1 day (a, d) and 2 days (b, e). (c), (d) are magnified imagesBack to article page
