Морфометрический анализ межтканевых взаимоотношений “эпителий-мезенхима” ротовой полости человека в раннем пренатальном периоде онтогенеза

Abstract

The author has carried out a karyometric analysis of intertissue correlations between “epithelium-mesenchyma” of the human oral cavity on 45 series of histological sections of human embryos and prefetuses, measuring 2.5-70.0 mm of the parieto-coccygeal length (PCL, рос. – ТКД), aged 3-12 weeks of intrauterine development (levels X-XII of development according to Stritter and stages 9-23 of Carnegie’s Institute). It has been established that prior to the appearance of morphological differences between various versions of the epithelia and mesenchymal derivatives of the oral cavity, the cell nuclei significantly differ by their dimensions. The most differentiated tissues of the human oral cavity have cells with nuclei of smaller sizes.
