The eye develops in the anterior region of the embryonic neural plate and is one of the first organs to form. Among other eye tissue, this region gives rise to the complex neural tissue, the retina. In blinding diseases like Age-Related Macular degeneration or Retinitis Pigmentosa, these light-sensing cells are lost and the human body cannot replace them. The Viczian team is interested in understanding the genes encoding transcription factors that drive the development of retina formation from pluripotent embryonic cells. In a 20+ year collaboration with the Zuber lab, our groups have been discovering the transcription factors and their roles in driving both of these processes. We use the relatively simple frog to better understand early eye formation (Fig. 1).
We generate transgenic tadpoles to determine elements driving gene expression (Fig. 2).
We use transplantation studies to determine transcription factors necessary and sufficient for eye formation (Fig. 3).
We believe in group effort and we champion our trainees to discover the best of their abilities in performing their research. Our current work has transitioned from using frog to knockout mouse studies and embryonic stem cell cultures to determine conservation of gene function from frog to mouse. We look forward to you joining us in this supportive, yet exciting, environment.
