The report presents research activities at the Norwegian Center for Stem Cell Research located at Oslo University Hospital and the Institute of Basic Medical Sciences, University of Oslo. The Center´s research focuses on hiPS cell production, differentiation, characterization and genetic modification (TALEN and CRISPR/CAS approaches), the role of epigenetics and DNA repair in stem cell differentiation, as well as neural imaging and functional assessment (including neuro-optogenetics). The University of Oslo Medical Faculty is establishing bilateral agreements with research and teaching institutions in St. Petersburg.

Repair of hyaline cartilage is among the current priorities in experimental and clinical research at the Center, in projects headed by group leader Jan Brinchmann. In vitro expanded chondrocytes are used for hyaline cartilage replacement, but they typically give rise to fibrous cartilage. The Brinchmann lab has implicated several factors relevant to in vitro chondrogenesis of human mesenchymal stem cells, as shown by high throughput mRNA profiling (Brinchmann et al., 2012) and is now collaborating with group leader Judith Staerk to use TALEN/CRISPR technology for targeted genetic manipulation. The CRISPR/Cas system can be used to direct Cas9 to specific genomic regions where it introduces DNA double-strand breaks. The regulatory system involves a non-coding guide RNA (gRNA), tracrRNA and the Cas9 protein. Staerk´s group has used this system to develop human iPS/ES cells with fluorescent reporters in the Brachyury, Flk1, CD34 and CD45 genetic loci, and is employing these in in vitro models of myelodysplastic syndrome, including genetic modifications introduced into hematopoietic stem cells. The Staerk group is also differentiating hES cells into blood cell precursors, and is also working on the expansion and maintenance of umbilical cord blood CD34+ cells.

The search for physiologically relevant tissue models includes the development of 3D cell culture systems representing new technological platforms for in vitro tissue engineering. Group leaders Gareth Sullivan and Joel Glover are applying 3D cell printing technology to develop multicellular assemblies of liver and neural tissue. Such 3D cellular systems applied to human stem cells and their derivatives can be utilized to investigate various heritable disorders affecting hepatocytes, neurons, cardiomyocytes etc.

In the field of oncology, the Center´s efforts are currently focused on dendritic cell-based vaccine for glioblastoma, in a clinical project led by group leader Iver Langmoen together with group leaders Gunnar Kvalheim and Brinchmann.Therapeutic vaccination against autologous cancer stem cells has been used for decades. However, one may expect better efficiency of such treatment using gliioblastoma mRNA-transfected dendritic cells from glioblastoma patients. A Phase I/II trial of vaccine therapy with hTERT, survivin and glioblastoma stem cell-derived mRNA-transfected dendritic cells has been conducted. Among positive effects of such therapy are decreased tumor size and increased median progression-free survival time (PFS), which was 19.9 months (in patients treated with transfected dendritic cells) treatment) versus 7.9 (with standard treatment).

The Center maintains two GMP cell production facilities for the establishment of autologous cell cultures and mRNA amplification, enabling GMP clinical production of human stem cells and their differentiated progeny performed under highly controlled conditions corresponding to EU Directives and Regulations.

Translational stem cell research has been defined as an area of national priority in Norway, leading to the establishment of the Center by an initiative from the Ministry of Health. The Center also maintains the National Core Facility for Production, Maintenance and Characterization of Human Pluripotent Stem Cells, the only such facility in Norway. This facility began using iPS cell technology in 2012 and its services are available to Norwegian and foreign researchers.
