.... Summary: High-resolution imaging reveals epithelia-to-mesenchyme transition (EMT) heterogeneity on the surface of developing mouse hearts. Proteoglycan again regulates epicardial EMT through dystroglycan localising within the Golgi apparatus. Epicardium EMT ECM Agrin Dystroglycan Golgi...

... migration, cells undergo cycles of coordinated attachment and detachment from the extracellular matrix (ECM). Embryonic migration processes that require cell-ECM attachment are dependent on the integrin family of adhesion receptors. Precise regulation of integrin-mediated adhesion is important for many...

.... Summary: Estrogen receptor (ER) α palmitoylation is required for mammary epithelial cell stem cell function, intercellular and intercompartmental communication with altered expression of paracrine factors and impaired ECM remodeling/protease function. Estrogen receptor alpha Membrane initiated...

...Georg Wolfstetter; Ina Dahlitz; Kathrin Pfeifer; Uwe Töpfer; Joscha Arne Alt; Daniel Christoph Pfeifer; Reinhard Lakes-Harlan; Stefan Baumgartner; Ruth H. Palmer; Anne Holz ABSTRACT Basement membranes (BMs) are specialized layers of extracellular matrix (ECM) mainly composed of Laminin, type IV...

...Lindsay Marjoram; Christopher Wright The spatiotemporally dynamic distribution of instructive ligands within embryonic tissue, and their feedback antagonists, including inherent stabilities and rates of clearance, are affected by interactions with cell surfaces or extracellular matrix (ECM). Nodal...

... of different promoters, LTBP1 exists in two major forms, long (L) and short (S), each expressed in a temporally and spatially unique fashion. Both LTBP1 molecules covalently interact with latent TGF-β and regulate its function,presumably via interaction with the extracellular matrix (ECM). To explore...

... positional information to neighboring ECs. Taken together, we propose that EGFL7 defines the optimal path of EC movement by assuring the correct positioning of each EC in a nascent sprout. * Author for correspondence (e-mail: loni@gene.com ) 30 5 2007 © 2007. 2007 ECM EGFL7...

... with an altered macromolecular composition of the ECM structuring the cells' migratory pathways. The presented results, extend our knowledge on Has2 function and, for the first time, demonstrate a developmental role for CD44 in vertebrates. On the whole, these data underlie and confirm the emerging importance...

... of muscular dystrophy. Dystroglycan is a receptor for multiple extracellular matrix (ECM) molecules such as Laminin, agrin and perlecan, and plays a role in linking the ECM to the actin cytoskeleton;however, how these interactions are regulated and their basic cellular functions are poorly understood. Using...

...Hiroshi Shimizu; Xiaoming Zhang; Jinsong Zhang; Alexey Leontovich; Kaiyin Fei; Li Yan; Michael P. Sarras, Jr. As a member of the phylum Cnidaria, the body wall of hydra is organized as an epithelium bilayer (ectoderm and endoderm) with an intervening extracellular matrix (ECM). Previous studies...
