During embryogenesis, epithelia are considered to be highly plastic and able to switch back and forth between epithelia and mesenchyme, via the processes of epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET), respectively. https://www.jci.org/articles/view/39675

Embryonic development depends on epithelial cells changing into migratory mesenchymal cells, and then changing back into epithelial cells when they reach their destination. These interlinked cellular dynamics, termed epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET), have long been recognized as fundamental processes that drive development [1]. https://biosignaling.biomedcentral.com/articles/10.1186/s12964-021-00761-8
The transition of epithelial to mesenchymal cells is not irreversible, as several rounds of EMT and MET are necessary for the final differentiation of specialized cell types and the acquisition of the complex three-dimensional structure of internal organs. Accordingly, these sequential rounds are referred to as primary, secondary, and tertiary EMT (Figure 1).

Cellular plasticity is fundamental to embryonic development. The importance of cellular transitions in development is first apparent during gastrulation when the process of epithelial to mesenchymal transition transforms polarized epithelial cells into migratory mesenchymal cells that constitute the embryonic and extraembryonicmesoderm. https://cir.nii.ac.jp/crid/1364233269608738688

Prepubertal vulvovaginitis January 2018Journal of Nature and Science of Medicine 2(1) DOI:10.4103/JNSM.JNSM_33_18 License CC BY-NC-SA The majority of cases are due to nonspecific vulvovaginitis in which vaginal cultures will grow organisms considered to be part of the normal flora. The condition is easily managed with good perineal hygiene. In reluctant cases, oral antibiotics or local estrogen cream may be helpful.
The OSNA (One-Step Nucleic Acid Amplification) assay is a RT-PCR-based technique for detecting CK19 mRNA. It is a quantitative, fast, and standardised assay, and it has been validated for lymph node molecular analysis in breast and CRC [11,12,13].
A novel technique for pathological examination, OSNA, uses the reverse transcription loop-mediated isothermal amplification method to amplify CK19 mRNA.
The lung is composed of endoderm derived epithelial cells that constitute the luminal surface of the airways and alveolar spaces. Ensheathing the epithelium are mesenchymal derivatives including airway smooth muscle, pulmonary fibroblasts, and vascular endothelium. During development, the epithelium and mesenchyme are involved in a complex circuit of paracrine and autocrine signals that act to drive morphogenesis and patterning of the developing airway structure. The lung initially arises from the anterior foregut endoderm region, which itself arises from the definitive endoderm that develops soon after gastrulation. .
