Role for laminin-alpha 5 chain LG4 module in epithelial branching morphogenesis
(2003) In Developmental Biology 263(1). p.153-164- Abstract
- Laminin-alpha5 chain was localized in all epithelial basement membranes (BMs) of mouse submandibular gland (SMG) from the onset of branching morphogenesis and became restricted to BMs of epithelial ducts in the adult. To investigate whether the laminin-alpha5 chain plays a role in branching morphogenesis, a set of cell-adhesive peptides from the C-terminal globular domains (LG1-5) was tested for their effects in SMG organ cultures. One peptide, LVLFLNHGH (A5G77f), which represents a sequence located in the connecting loop between strands E and F of LG4. perturbed branching morphogenesis and resulted in irregularities in the contours of epithelial structures, with formation of deep clefts. The data suggest a role for the laminin-alpha5 LG4... (More)

One peptide, LVLFLNHGH (A5G77f), which represents a sequence located in the connecting loop between strands E and F of LG4. perturbed branching morphogenesis and resulted in irregularities in the contours of epithelial structures, with formation of deep clefts. The data suggest a role for the laminin-alpha5 LG4 module in the development of the duct system, rather than in the bifurcation of epithelial clusters. The epithelial BM of A5G77f-peptide-treated explants was continuous, which was in contrast to our previous finding of impaired epithelial BM assembly in explants treated with the larninin-alpha1 LG4 module peptide, or with a monoclonal antibody against this domain. A5G77f also perturbed in vitro development of lung and kidney. These results suggest a crucial role for the LG4 module of larninin-alpha5 in epithelial morphogenesis that is distinct from that of the laminin-alpha1 LG4. (C) 2003 Elsevier Inc.
