Speaker: Dr. Winfried Neuhuber, Professor, University of Erlangen-Nürnberg, Institute of Anatomy and Cell Biology, Germany
March 3, 2022
Winfried Neuhuber is FAU Senior Professor of Anatomy in the Institute of Anatomy and Cell Biology at Friedrich-Alexander-Universität Erlangen Nürnberg (Germany). His research focus is on the functional anatomy of the autonomic nervous system, in particular innervation of the gastrointestinal tract using neuronal tract tracing and immunohistochemistry. In this talk, he will present some examples of organs which are targeted by both efferent and afferent vagal neurons. In contrast, he will discuss older and more recent claims of vagal innervation which most likely resulted from tracing artifacts or other misconceptions.
Speaker: David Ornitz, MD, Ph.D., Alumni Endowed Professor Washington University School of Medicine in St. Louis
February 3, 2022
David Ornitz is an Alumni Endowed Professor in the Department of Developmental Biology at Washington University School of Medicine. His research uses molecular, genetic, and biochemical approaches to study mesodermal and epithelial patterning, organogenesis, tissue homeostasis, and response to injury.
The Ornitz lab has a particular interest in the function of Fibroblast Growth Factor (FGF) signaling pathways in endochondral bone development, postnatal bone growth, and bone homeostasis. In this talk he will explore the role of an FGF receptor (FGFR) signaling center that is located in a unique perichondrial cell population that functions to regulate the activity of the adjacent growth plate.
He will then discuss studies that explore a novel role for FGFR signaling in the maintenance of osteocyte viability and skeletal homeostasis in adult mice.
Speaker: Elaine A. Ostrander, Ph.D., National Human Genome Research Institute

The Ostrander laboratory is interested in understanding the genomic factors which control the enormous amount of morphologic, disease susceptibility and behavioral variation observed in canines across the world. She has studied canine evolution, genome structure and breed formation, producing a clear understanding of how most individual breeds developed. Her most recent focus has been on morphology and evolution, as she seeks to understands the genetic underpinning of morphologic variation of canids, past and present, throughout the world.
Speaker: H. Joe Yost, Ph.D., University of Utah
August 31, 2021
The Yost laboratory seeks to understand the gene regulatory networks and developmental mechanisms that define the identity and position of cells in vertebrate embryos and to utilize this knowledge for the advancement of human medicine. This requires integration of model organism genetics with the discovery of novel disease-causing mutations in human genomes, and the Yost laboratory is recognized as a leader in understanding vertebrate left-right development and its contributions to complex congenital heart defects, which affect approximately thirty-five thousand births per year in the US.

The pancreas is a flat elongated pear shaped organ positioned behind the stomach. It is part of the digestive system and endocrine system of vertebrates. The pancreas synthesizes pancreatic juices, which contain enzymes that aid in digestion, and it produces several hormones, including insulin which regulates blood sugar levels. But what controls pancreas development and function? To date, only a handful of regulatory have been thoroughly characterized and many of the molecular pathways that specify islet cell differentiation and function are poorly understood.

How does muscle develop, regenerate, maintain, age, and evolve? These are the questions that drive our research. We focus on muscle stem cells because they are the source of all muscle. We focus on the muscle connective tissue because it provides the niche for muscle stem cells and is critical for muscle form and function. We study how interactions between muscle stem cells and the connective tissue orchestrate development of limb muscles and the diaphragm, regulate muscle regeneration and aging, are the source of birth defects and fibrosis, and shape evolution of the musculoskeletal system.

Sometimes the data that are generated by experiments are very far from what is anticipated. As part of a translational project using cartilage to heal large bone defects, we discovered that chondrocytes transform into osteoblasts. This outcome contradicts more than 100 years of dogma that apoptosis is the terminal fate of chondrocytes, and has led to a discovery of new mechanisms of bone regeneration.
