The goal of my lab is the study of the cellular and molecular mechanisms of spine development and homeostasis using explicit animal models. We choose to utilize both mouse and zebrafish models to provide complementary approaches to study musculoskeletal development and disease. For instance, we developed a conditional mouse model of idiopathic scoliosis (IS) by removing Gpr126/Adgrg6 function in osteochondral progenitors (Human Molecular Genetics, 2015). Mechanistic studies of this mutant mouse model have begun to focus our investigation towards the identification of mechanisms of cartilage homeostasis and joint degeneration. We have also shown that zebrafish can model aspects of IS (Development Dynamics, 2014), as well as, other vertebral malformations relevant to human disease (Developmental Biology, 2014). In an effort to promote gene discovery, we also utilized the power of zebrafish genetics to identify a collection of scoliosis mutant zebrafish. Our studies in both zebrafish and mouse have begun to identify common mechanistic roles for scoliosis and hydrocephalus affecting alterations in the physiology of the cerebrospinal fluid (PLOS Genetics, 2018). We will continue to use a multi-tiered approach, combining zebrafish, mouse, and cell culture models, informed by human genomic studies, with the goal to inform the diagnosis of pediatric/musculoskeletal diseases and provide avenues for therapeutic interventions of these disorders in humans.
