The developmental stages of and places for the proliferation of tongue muscle cells have not yet been determined. To determine the stages of and places for proliferation between embryonic day (E) 9 and birth, we analyzed the expression of cyclin D1 mRNA and the immunolocalization for proliferating cell nuclear antigen (PCNA). The ratio of PCNA-positive nuclei to total nuclei (PCNA-labeling index) was obtained in the anterior, middle, and posterior regions. Cyclin D1 mRNA was highly expressed between E11 and E13, but decreased thereafter until birth. The distribution of PCNA-positive cell nuclei was consistent with that of myogenic cells in the occipital somites at E9. The PCNA-labeling index was highest at E11, then decreased until birth without a significant difference among the 3 regions. These findings suggest that some tongue muscle progenitor cells begin proliferation in the occipital somites at E9, and that the proliferation in the whole tongue region occurred most actively between E11 and E13, then decreased until birth without regional differences.
