Bit Bio

Dr. Tony Oosterveen is a senior scientist and CNS group leader at Bit Bio, a biotech company located in Cambridge (UK) that uses proprietary technologies to efficiently and robustly reprogram human cells for research, drug discovery, and cell therapy. During his career, Dr Oosterveen extensively studied the transcriptional principles that underlie cell specification processes in the developing CNS and has applied this knowledge to generate specific neuronal subtypes from human pluripotent stem cells. He received his MSc in Developmental Biology from the University of Groningen (1997) and performed successfully his PhD studies at the Hubrecht Institute for developmental and stem cell biology (University of Utrecht, 2002). He carried out post-doctoral research at the Karolinska Institute (Stockholm) and resolved a long-standing question in the field on how morphogens in the vertebrate embryo are interpreted at the transcriptional level in a concentration- and tissue-dependent manner (Wenner Gren and Marie Curie fellowships). He continued as a senior investigator at the MRC toxicology unit (University of Cambridge), where he generated from human pluripotent stem cells distinct subtypes of dopaminergic neurons to model Parkinson’s disease in a dish. Thereafter, he joined the biotech company Synpromics (Edinburgh) to develop gene therapy approaches that target specific cell types in the CNS to treat neurological diseases. In his current role at Bit Bio, Dr. Oosterveen is leading distinct projects that use a proprietary discovery platform and genetic switch to express optimal sets of transcription factors to reprogram iPSCs towards pure neuronal subtypes and glia cells.

Collection Overview

Human brains differ remarkably in size, shape and cellular composition from the animal models used in pre-clinical research. Differences at the molecular and cellular levels set our brains even further apart from these models. In particular, human cortical neurons have in comparison to rodent models larger dendritic trees, distinct electrophysical properties, ten times the capacity to transfer information, as well as different types of protein isoforms and 30% additional proteins present in their synapses. Not surprisingly, the translation of findings derived from animal models to the clinic has been proven to be very limited (especially for neurological indications whereby less than 10% of the pre-clinical drug candidates are entering the clinic). Therefore, human in vitro models will be invaluable for drug development in order to reduce costs, improve discovery screen specificity, and potentially save lives. Human iPSC-derived neurons are an attractive in vitro model for high content drug screening platforms. However, directed differentiation protocols that use extrinsic factors are often complex, lengthy, expensive, inconsistent, and generate mixed cell populations. In contrast, transcription factors which operate in a cell intrinsic manner have the extraordinary ability to efficiently reprogram cells toward specific cell types. This methods collection aims to collate advanced approaches that utilize cellular reprogramming in order  to model neurological diseases, and will include methods describing; (1) the identification and screening for transcription factors critical for cellular reprogramming; (2) viral and non-viral based delivery systems to reprogram cells; and (3) the use of reprogrammed cells in neurological disease modelling.
