Case Studies

Collaboration between Prof. Federico Calegari and Exiqon A/S (Denmark) for detection of circular RNAs (circRNAs) and their associated molecular complexes using Exiqon's LNA™ oligonucleotide probes.

Newly discovered circular RNAs (circRNAs) may play many important biological functions, particularly in brain development. To capture circRNAs of interest, as well as their associated molecular complexes, and elucidate their functions and molecular mechanisms, Prof. Federico Calegari's group and Exiqon A/S ( are cooperating to investigate the use of Exiqon's proprietary oligonucleotide probes (LNA™ technology) for circRNA isolation. Prof. Calegari said, "Current limitations in available research tools and methods for analysing the RNA interactome hinder the understanding of complexity in circRNA functions. Together with Exiqon we will assess the LNA™ technology to overcome these limitations and provide insight into the functions of circRNAs".

Within a BMBF funded project Prof. Marius Ader is collaborating with Miltenyi Biotec for the identification of cell surface markers allowing enrichment of iPS-derived retinal cells for transplantation.

The groups of Prof. Marius Ader and Dr. Mike Karl at the CRTD are developing protocols for the generation of transplantable retinal cells from human induced pluripotent stem cells (hiPS). In a joined effort with Miltenyi Biotec ( cell surface markers for the classification and enrichment of specific donor cells for cell-based treatment approaches in retinal degenerative diseases will be identified as an essential step in therapy development for blinding diseases.
