Evolution of the sponge body plan: Wnt and the development of polarity in freshwater sponges
DownloadSpring 2014
Body polarity is a fundamental aspect of all multicellular organisms. Metazoans – animals – are monophyletic, but is body polarity homologous among all phyla? Sponges are considered to have branched off first from other animals and therefore studies of polarity formation in the simple sponge body...

Roles for Transcription Factors and Signaling Pathways in Hindbrain Segmentation and Ventricle Morphogenesis
DownloadFall 2018
During development, expression and localization of transcription factors and transcriptional co-regulators must be tightly controlled, and in turn they are required to regulate cellular identity and cellular processes. Often this involves complex interactions with signaling pathways. We are...

Axial patterning of the developing vertebrate eye is crucial for proper axon pathfinding, as well as critically important morphogenetic events such as closure of the ocular fissure. Perturbations in eye morphogenesis can lead to ocular coloboma (failed ocular fissure closure) and microphthalmia...
