2. Modulation of retinal progenitors : A bird’s-eye view of retinal regeneration and disease
Abstract : The cell populations of the retina and their intricate organization provide us with one of the most important senses – vision. All retinal cell populations are derived from a common progenitor pool as a result of tight regulation of proliferation, differentiation, dedifferentiation, and programmed cell death. READ MORE

3. Models of Retinal Development and Disease
Abstract : For a model of a human disease to be valid and useful, it is important that key genotypic and phenotypic traits are shared between model system and human. The work in this thesis has been focused on generating new and characterizing spontaneous models of three genetic disorders affecting the retina: retinoblastoma, a childhood cancer with its origin in the fetal retina, Stargardt disease, a juvenile form of macular degeneration, and Bardet-Biedl syndrome, a pleiotropic ciliopathy featuring retinal degeneration.

Retinopathy of prematurity (ROP) and neurological complications are well known reasons for visual dysfunctions, but preterm children with no or only mild ROP and no evident neurological problems may also be affected visually when they grow up.
