The Fuhrmann Laboratory
Sabine Fuhrmann received her Ph.D. from the University of Freiburg in Germany and postdoctoral training at the University of Washington/Seattle, investigating the role of tissue-tissue interactions during early eye development. In 2000, she joined the faculty at the Moran Eye Center. Her laboratory studies the role of extra cellular signaling pathways in regulating patterning and differentiation of ocular tissues such as the neural retina and pigmented epithelium. The molecular signals that mediate these patterning events are largely unknown. Multiple congenital eye disorders, including anophthalmia, micropthalmia, aniridia, coloboma, and retinal dysplasia, stem from disruptions in early eye development. It is thus critical to define the signals that regulate normal patterning and development of the optic vesicle. The goal of Dr. Fuhrmann’s research is to elucidate the cellular and molecular mechanisms that regulate the patterning and differentiation of ocular tissues using chick and mouse as model organisms.
During development, complex patterning events generate distinct tissue components of the eye. Dr. Fuhrmann’s lab has recently shown that tissues surrounding the embryonic eye control this development. Since signaling molecules like “TGFbeta” and “Wnts” control early patterning and differentiation of the brain and spinal cord, they are studying the role of these signaling molecules during early eye development using molecular genetics technologies, tissue culture and animal models.

Many inherited and some induced eye defects arise in utero and lead to devastating blindnesses. At present there is neither any cure for such defects, nor are they easy to detect in advance. Dr. Fuhrmann’s research is critical to the process of identifying genes associated with such events, and is the first step in defining points of potential intervention. The Fuhrmann Laboratory is the Moran Eye Center’s lead team in identifying early eye gene defects and decoding their molecular interactions.
