title: Reconstitution of the basement membrane from the inner and outer dental epithelia of trypsin-isolated mouse molar enamel organs.
abstract: Trypsin-isolated embryonic mouse enamel organs were cultured on top of plasma coagulum. Inner and outer dental epithelia in contact with the plasma coagulum synthesized a new basement membrane as revealed by electron microscopy and 3H-glucosamine autoradiography. The outer dental epithelium in contact with air did not redeposit a basement membrane. The plasma coagulum had beneficial effects on basement membrane reconstitution and maintenance by inhibiting the process of keratinization.
