The Role Of The Basement Membrane In Basal Tissue Folding, Elizabeth Falat
Theses and Dissertations
The ability of organs and tissues to function properly is reliant on the correct formation of shape. Proper morphogenesis is carefully regulated by both intracellular dynamics and extracellular mechanical forces. Using the highly conserved zebrafish midbrain-hindbrain boundary (MHB), we investigated the role of the basement membrane, a specialized extracellular matrix that basally lines the tissue, in mediating cell shapes and mechanical tissue stresses during basal tissue folding. A primary component of the basement membrane is laminin-111, a heterotrimer composed of the alpha1, beta1 and gamma1 chains, encoded by lama1, lamb1a, and lamc1 genes respectively. We investigated the role of each …
