Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelObservational studyOther

    Tβ4 signals were observed in almost all ameloblastomas, in both peripheral columnar cells and central polyhedral/angular cells.

    In plain wordsIn nearly all samples of ameloblastoma, a tooth tumor, the body's own Tβ4 was present.

    Summary · context
    We immunohistochemically evaluated the expression of Tβ4, ameloblastin (AMBN), amelogenin (AMEL) and enamelin (ENAM) in 57 samples of ameloblastomas from 40 patients, and also assessed the expression of these molecules in 11 cases of odontomas, two of ameloblastic fibro-odontomas and one of tooth ge…

    Tβ4 signals were not seen in odontomas.

    In plain wordsThe body's own Tβ4 was not found in odontoma samples, a different kind of tooth growth.
