Abstract

Basement membranes (BMs) are cell-associated extracellular matrices formed initially as laminin Dolymer scaffoldings. They act as solid-phase agonists for adherent tissue cells, profoundly affecting their differentiation, organization and maintenance. Defects of BM components and structure are a cause of Aim I. Role of laminin LG domain-dependent anchorage.
Aim II. Post-anchorage laminin and basement membrane functions.
Aim 1 11. Architectural and other laminin short-arm functions. To address these, we propose to integrate the approaches of using recombinant laminins with specific function- altering mutations to analyze assembly and cell differentiation in normal and genetically-modified EBs, renal tubular epithelial and other BM-assembling cells backed by mouse genetics to validate our hypotheses.
