Figure 5. Filipin-cholesterol complexes are seen along odontoblast cell processes in predentin (a). The density of filipin-cholesterol aggregates/µm² is enhanced in dentin (b). The density is low along the Tomes' processes (c), and high for membrane remnants in the forming enamel (d). (a) x54,000, (b,c) x27,000, (d) x32,000.
