Research Program:
Muscle Development and Morphogenesis in Zebrafish

A large variety of diseases, both inherited and acquired, affect muscle tissues in humans. In order to prevent and/or treat such disease, it is necessary to understand the pathology at the cellular and molecular level. Because each step of muscle specification and differentiation translates to a progressive refinement of functional physiology, studying muscle development may lead to therapeutic insights. The goal of our laboratory is to elucidate the signaling networks that underlie the muscle morphogenesis.

We study skeletal muscle morphogenesis during zebrafish development. Skeletal muscle is comprised of segmentally reiterated myotomes. Like the mammalian tendon, the zebrafish myotome boundary transduces force from muscle to the skeletal system. Thus, myotome boundary formation, as well as skeletal muscle morphogenesis, is critical for normal development and muscle function. Our research investigates the morphogenetic signaling networks that underlie skeletal muscle and myotome boundary formation.

The zebrafish is an excellent model system with which to integrate the genetic, molecular, and cell biological mechanisms that underlie muscle development. Because the signaling networks that regulate muscle development are remarkably conserved among vertebrates, our studies may lead to novel insights into development of therapeutics for muscle and tendon diseases.
