Stem Cells and Neurogenesis in the Retina (SCaNR)
Center for Eye Research and Therapy in Ophthalmology (CERTO)
In brief
Our SCaNR research group is associated with the private laboratory of Retina France association, the CERTO. This allows us the originality of a double scientific approach, fundamental and applied. Using both Xenopus and the mouse as animal models, we seek to understand the mechanisms underlying the development, survival and regeneration of retinal cells, with the objective of therapeutic strategies, including neuroprotection, gene therapy and cell therapy.

Our goal is to contribute to scientific advances allowing the development of innovative therapeutic approaches for patients suffering from degenerative retinal diseases such as Retinitis Pigmentosa (RP) or Age-related Macular Degeneration (AMD).
Stem Cells and Retinal Regeneration
Cell therapy aims at revitalizing the regenerative capacity of the retina, which is naturally extremely limited in mammals. On the contrary, in fish or amphibians, different populations of stem cells contribute efficiently to the repair of the retina after injury. These species are therefore models of interest to dissect the signaling pathways controlling regenerative processes and thus to provide essential information to stimulate the proliferation and neurogenic potential of dormant mammalian retinal stem cells. In this context, we study and compare in Xenopus and mice, two models with very different regenerative capacities, the mechanisms underlying the maintenance, recruitment and activity of adult retinal stem cells under both physiological and pathological conditions of retinal degeneration.
Gene therapy
In recent years, gene therapy in the field of ophthalmology has shown extremely promising results. The objective of our preclinical study in mice is to develop a new gene therapy product based on the use of an AAV virus and targeting retinopathies associated with dominant mutations in the CRX gene.

Within our team, and thanks to this plastform, we have develop transgenic and genome editing tools as well as various knock-down techniques. Here are some examples:
- Using the REMI transgenesis technique, we have developed an inducible and reversible photoreceptor degeneration model in Xenopus laevis to study retinal regeneration processes (see Chesneau et al. Methods Mol Biol. 2018; Langhe et al., Glia 2017).
- We generate and/or maintain in the laboratory transgenic lines, such as reporter for signaling pathways (Wnt: Borday et al. Plos One 2018; Borday et al. Development 2012) or specific to a retinal cell type such as Müller cells (work in progress).
- We have developed models of retinitis pigmentosa (a degenerative photoreceptor disease in humans) in both Xenopus laevis and Xenopus tropicalis using CRISPR-Cas9. These models allow us to study the reactivation of stem cells under pathological conditions (work in progress).
- We routinely use morpholino antisense oligonucleotides to block the translation or splicing of a target gene. We have developed the use of photoactivatable morpholinos allowing inducible or reversible loss of function (see Cabochette et al. Elife 2015).
- Until now, to study the function of a protein, scientists have used techniques targeting the gene or transcripts encoding the protein of interest. We have recently developed a new technique in Xenopus called Trim-Away, which allows to directly deplete a protein (work in progress). This technique exploits the properties of a recently discovered protein called TRIM21 which, in combination with an antibody recognizing the protein of interest, has the remarkable ability to target the antibody-protein complex towards its destruction in the proteasome.
- Given these expertises in Xenopus, we regularly establish collaborations with teams outside the laboratory (some examples: Sena et al. Development 2019; Della Gaspera et al., Dev Biol 2018; Schietroma et al., JCB 2017; Kaya et al. J. Neurosci. 2012).
