Stem Cell Markers Reveal Conservation of Tooth and Hair Regeneration
Meeting Abstract 35-8 Sunday, Jan. 5 09:45 – 10:00 Stem Cell Markers Reveal Conservation of Tooth and Hair Regeneration SQUARE, TA; University of California, Berkeley square@colorado.edu Vertebrates interact directly with their environment largely through their epithelia. To enhance these interactions, most vertebrates deploy various accessory structures in these high-contact regions of their bodies, called epithelial appendages. These […]

Modeling rodent tooth morphogenesis reveals constraints on mammalian tooth evolution
Meeting Abstract 35-1 Sunday, Jan. 5 08:00 – 08:15 Modeling rodent tooth morphogenesis reveals constraints on mammalian tooth evolution BURROUGHS, RW; University of Chicago rburroughs@uchicago.edu Mammal tooth morphology and function correlate strongly with dietary ecology, and convergence is a major feature of mammalian tooth evolution. Yet, function and ecology are insu cient to explain morphological diversi […]
