Abstract
Epithelial mesenchymal transition (EMT) in development, tissue repair and carcinogenesis involves cellular plasticity with varying degrees of epithelial and mesenchymal properties. Several recent studies have focused on EMT phenotypic dynamism; however, information on cellular interaction in the context of EMT is inadequate. In our previous study, we investigated EMT phenotypic plasticity and anticipated it as a population driven interactive process. Present study has characterized cellular connectivity as a representative of interactivity during EMT in epithelial normal and cancer cell. It has also explored dynamism of connectivity and phenotype employing Markov model. Further, plasticity was substantiated with cell surface microvilli and molecular marker. The study unveiled interplay between phenotype and connectivity too. Findings have revealed that intercellular connectivity fueled EMT plasticity and its dynamism was more prominent in cancer population. However, normal cells are more vibrant in transition and phenotypic plasticity. We have proposed connectivity plasticity as a hallmark of EMT and needs to be studied in depth. Present study also paves the way in translating in vitro EMT findings in histopathological practices.
