Diekwisch Lab: Craniofacial Research

 

While most of our lab projects focus on fairly late events in craniofacial development, such as enamel and periodontal development, TMJ function and tooth movement, we also have a series of collaborative papers involving earlier aspect such as skull and muscle development. Currently, we are using a number of mouse models to understand genetic and epigenetic factors involved in craniofacial development and disease.

 

Skulls of the duBrul Collection. E. Lloyd du Brul was a legendary Anatomist, Teacher, and Oral Anatomy Department Head at UIC.His skull collection is now housed at UIC College of Dentistry, thanks to a generous gift from his wife Florence.

Myofibrils in the striated muscle of the tongue. Alternating A and I bands are indicative of the periodic organization of muscle fibers into sarcomeres. Muscle fibers are multinucleated structures consisting of multiple myoblasts, each of them contributing a nucleus for optimum fiber function.
