BioMediTech Research Groups

Neuro Group

Group Leader: Adjunct Professor Susanna Narkilahti


About Us

The BioMediTech Neuro Group focuses on producing both neuronal and glial cells from human pluripotent stem cells. The aim is to characterize the produced cells by their gene and protein expression and specifically study the cells’ maturation and electrophysiological functionality both in single cell and network levels. Co-culture systems containing several cell types in 2- or 3D utilizing biomaterials are also established. The group focuses on applications in e.g. in vitro modeling of biological processes and neurological diseases, graft development, and neurotoxicity screening platforms.
