Meeting Abstract S3.1-4  Saturday, Jan. 4 09:30  Planar cell polarity and the developmental control of cell behavior WALLINGFORD, John; HHMI/UT, Austin wallingford@austin.utexas.edu Planar cell polarity (PCP), the orientation and alignment of cells within a sheet, is a ubiquitous cellular property that is commonly governed by the conserved set of proteins encoded by so-called “PCP genes.” The PCP […]

Meeting Abstract S3.3-3  Saturday, Jan. 4 14:30  Old cell new trick: cnidocytes as a model for studying the evolution of novelty BABONIS, L.S.*; MARTINDALE, M.Q.; Whitney Lab for Marine Bioscience, Univ of Florida; Whitney Lab for Marine Bioscience, Univ of Florida babonis@whitney.ufl.edu Understanding how new cell types arise is critical for understanding the evolution of organismal complexity. […]

Meeting Abstract S3.1-2  Saturday, Jan. 4 08:30  Mechanisms of egg chamber elongation in Drosophila HORNE-BADOVINAC, Sally; The University of Chicago shorne@uchicago.edu During development, discrete organs and entire body plans emerge from the coordinate actions of individual cells. These complex morphogenetic events require dynamic regulation of cell shape, polarity, and adhesion across cell populations. My lab seeks to […]

Meeting Abstract S3.2-2  Saturday, Jan. 4 11:00  How a single gene twists a snail KURODA, Reiko*; ABE, Masanori; Tokyo Univ. of Science; Tokyo Univ. of Science rkuroda@rs.tus.ac.jp Gastropod Lymnaea (L.) stagnalis has unique features, i.e. , the chirality, the sinistrality and the dextrality, is hereditary, determined by a single locus that functions maternally at the very early […]

Meeting Abstract S3.3-2  Saturday, Jan. 4 14:00  Heterogeneity in planarian neoblasts by single cell analysis VAN WOLFSWINKEL, JC*; WAGNER, DE; REDDIEN, PW; Whitehead Institute for Biomedical Research – MIT, Cambridge; Whitehead Institute for Biomedical Research – MIT, Cambridge; Whitehead Institute for Biomedical Research – MIT, Cambridge josien@wi.mit.edu Planarians have a legendary capacity for adult regeneration that is […]

Meeting Abstract S3.2-3  Saturday, Jan. 4 11:30  Epithelium establishment and tentacle development in Nematostella vectensis GIBSON, Matt*; IKMI, Aissam; FRITZ, Ashleigh; RAGKOUSI, Katerina; Stowers Institute for Medical Research mg2@stowers.org Evolution of the capacity to form secondary epithelial outgrowths from the principal embryonic axes was a crucial innovation that potentiated the diversification of animal body plans. Nevertheless, the […]

Meeting Abstract S3.3-4  Saturday, Jan. 4 15:00  Ectodermal inputs into patterning skeletogenesis LYONS, Diedre; MCINTYRE, Dan; MCCLAY, David R.*; Duke University; Duke University; Duke University dmcclay@duke.edu Sea urchin larvae produce a skeleton using a limited number of skeletogenic cells, usually either 32 or 64 cells depending on the species. Each skeletogenic cell is capable of producing any […]

Meeting Abstract S3.1-1  Saturday, Jan. 4 08:00  Dynamics of Tissue Morphogenesis in Ascidians MUNRO, E.M.*; HASHIMOTO, H.; ROBIN, F.R.; SHERRARD, K.M.; University of Chicago; University of Chicago; University of Chicago; University of Chicago emunro@uchicago.edu A key challenge in developmental biology is to understand how embryonic cells organize force production in space and time and how these forces […]

Meeting Abstract S3.5  Sunday, Jan. 4 10:30  the evolution of unidirectional, pulmonary airflow FARMER, CG; University of Utah cg.frmr@gmail.com http://www.farmerlab.com/ Bird lungs have conventionally been thought to be unique in having air flow through most of the conducting airways in the same direction during both inspiration and expiration. Aerodynamic valves cause unidirectional flow through a circular system […]

Meeting Abstract S3.1  Sunday, Jan. 4 08:00  When Past is Not Prologue: Neosuchian Phylogeny and the Origin of Crocodylia BROCHU, C. A.*; BURKEY, M. R.; JOUVE, S.; MILLER-CAMP, J.
