Panel A, incisors from either animals homozygous to the amelogenin M180 knock in allele (KI/KI), or wild type amelogenin allele (Wt/Wt), are shown at six weeks of age. No discernable alterations to the morphology of the incisors or their capacity to masticate food are identified.
Panel B and C, enamel was visualized by scanning electron microscopy from wild type (B) or M180 knock in (C) teeth and reveals no discernible alteration to enamel architecture.
