Petersen, Sarah Catherine (2011-12-10)Department: Cell and Developmental BiologyInformation flow in nervous systems depends on the asymmetric organization of neurons; neurotransmitters are released from presynaptic domains and stimulate receptors localized to postsynaptic regions. These specialized ...

Halstead, Angela Marie (2014-11-06)Department: Cell and Developmental BiologyThe TGF-â ligand Nodal is a key regulator of body axis formation and patterning in the developing vertebrate embryo. How the Nodal signaling pathway is activated and regulated, and how precise spatiotemporal control of ...

Von Stetina, Stephen Edward (2005-11-07)Department: Cell and Developmental BiologyProper function of the brain requires that neurons adopt different morphologies and connections. In the nematode <i>C. elegans</i>, VA and VB motor neurons arise from a common precursor cell but adopt different morphologies ...

Smith, Cody Jean (2012-07-23)Department: Cell and Developmental BiologyOrganisms across phylogeny have neuronal circuits that control everyday activities. The somatosensory network, for example, is specifically utilized to sense the external environment and is important to properly inform ...

DeLaughter, Daniel Morris (2013-06-10)Department: Cell and Developmental BiologyEpithelial-to-Mesenchymal Transformation (EMT) is an important process in development, and occurs during key steps in both valvular and coronary vessel development. This dissertation uses transcriptional profiling strategies ...

Westmoreland, Joby Jackson (2007-11-28)Department: Cell and Developmental BiologyThe Nodal and Nodal-related morphogens are utilized for the specification of distinct cellular identity throughout development by activating discrete target genes in a concentration-dependant manner. Lefty is the principal ...

Boyer, Daniel Frederick (2006-12-04)Department: Cell and Development BiologyThe transcription factor Pancreatic and duodenal homeobox 1 (Pdx1) is essential for formation of the pancreas and for glucose-responsive insulin secretion from mature pancreatic beta cells. In humans and mice, heterozygosity ...
