The research aims to better understand the assembly of myofibrils in developing muscle by examining the bonds between myofilaments.
Followed intracellular assembly of myofibrils in developing muscle while applying various perturbations.
Isolated materials from mature fibrils to examine alterations in cohesive forces between myofilaments.
Observations on the effects of perturbations on fibrillogenesis are discussed.
Insights into the nature of transverse bonds that stabilize the myofilaments within myofibrils were obtained.
