Hepatocyte growth factor (HGF) plays central roles in tubulogenesis and metastasis [1-4]. HGF treatment of Madin-Darby canine kidney (MDCK) cells grown as cysts in three-dimensional culture induces tubulogenesis [5, 6], which like most tubulogenic processes proceeds through distinct intermediate phases. Identification of genes associated with these phases(More)
How cells communicate during development and regeneration is a critical question. One mechanism of intercellular communication is via exosomes, extracellular vesicles that originate by the fusion of multivesicular endosomes with the plasma membrane [1-8]. To model exosome-based intercellular communication, we used Madin-Darby canine kidney (MDCK) cell cysts(More)
Tubule formation in vitro using Madin-Darby canine kidney (MDCK) epithelial cells consists mainly of two processes. First, the cells undergo a partial epithelial-mesenchymal transition (pEMT), losing polarity and migrating. Second, the cells redifferentiate, forming cords and then tubules with continuous lumens. We have shown previously that extracellular(More)
Epithelial cells form tubular and acinar structures notable for a hollow lumen. In three-dimensional culture utilizing MCF10A mammary epithelial cells, acini form due to integrin-dependent polarization and survival of cells contacting extracellular matrix (ECM), and the apoptosis of inner cells of acini lacking contact with the ECM. In this paper, we report(More)
