Immunohistochemistry of Enamel Cell Proteins
High resolution images for teaching etc. are available on request
Light microscopy of a paraffin section of developing rat molar labelled with antibodies to PDI (protein disulfide isomerase) and counterstained with haematoxylin. The principal enamel cells (ameloblasts) and dentine-forming cells (odontoblasts) contain similarly high levels of PDI (dark brown). PDI is not detected in the developing hard tissues (enamel and dentine matrix). Image by Steve Shnyder and Mike Hubbard.
