Vår mitokondrielle stamcelleforskningsgruppe er lokalisert ved Institutt for klinisk medisin (K1), Universitetet i Bergen og er en del av Neuro-SysMed, Senter for fremragende forskning innen nevrologiske lidelser, Nevrologisk avdeling ved Haukeland Universitetssykehus. Vi bruker stamceller transformert fra en pasients egne fibroblaster for å studere mitokondrielle sykdommer forårsaket av POLG-mutasjoner. Målet til forskningsgruppen vår er å gjennomføre iPSC-baserte in vitro modellsystemstudier for å øke forståelsen av mitokondrielle sykdommer, identifisere de underliggende mekanismene til disse vanlige mitokondrielle sykdommene og utvikle en iPSC-basert plattform for å teste terapeutiske midler. Vi har etablert egenskapene og fasilitetene som kreves for omprogrammering og differensiering av iPSC-er, som muliggjør studiet av nevronceller fra pasienter og friske kontroller. Validerte iPSC-er kan differensiere til nevrale stamceller (NSCs) og kompartmentaliserte nevronale subtyper, så vel som astrocytt-/glialcellepopulasjoner. Vi har også nylig utviklet 3D hjerneorganoider for å studere sykdomsmekanismer og teste behandlinger. Vårt brede forskningsmål er å bestemme det biologiske og patologiske grunnlaget for nevrodegenerative sykdommer assosiert med mitokondriell dysfunksjon, og vi tar sikte på å utvikle dette og gjennomføre mer dyptgående molekylære fenotypingsstudier. Siden gruppen også er en del av Neuro-SysMed Center, vil vi bruke vår modell og stamcelletilnærming til å studere andre nevrodegenerative sykdommer som Parkinsons og Alzheimers.
