Development of therapeutics for CNS diseases with human personilized stem cell derived organoid models

​The Wolvetang group reprograms somatic cells from patients (eg skin or blood cells) into induced pluripotent stem cells that can make any cell type of the human body. Using CRISPR-Cas9 enabled genome manipulation technologies pathogenic mutations  are next either corrected or introduced to assess their impacts on diseases that affect brain development or function. Concurrently such cell lines are then often genetically modified to contain reporter systems that read-out disease phenotypes at scale. To mimick the human brain as closely as possible in vitro the patient specific cell lines and isogenic controls are next turned into various types of  brain and spinal cord organoids. By producing and interrogating these lentil-sized CNS avatars at scale with automatic robotic imaging platforms, single cell gene expression analyses, and functional read-outs on multi-electrode arrays features of genetic or environmentally induced neurological diseases are captured and quantified. We further have a keen interest how ageing leads to ageing-associated diseases such as Alzheimers disease and how this may be alleviated via prevention or elimination of senescence in the brain. Through computational and AI-assisted synthesis of these disease read-outs we strive to discover, design and test small molecule (drug) or genetic (mRNA or gene therapy) therapeutics, and for discovering disease biomarkers. We also leverage our advanced human CNS models to discover the cellular and molecular underpinnings of cognition and consciousness. All research programs ultimately aim to improve human health through accellerated discovery and pre-clinical testing of a variety of therapeutics in our human CNS models.

​Professor Ernst Wolvetang obtained his PhD from the University of Amsterdam, continued his post-doctoral training at the Monash Institute for Reproduction and Development, before joining the Australian Stem Cell Centre. In 2008 he was recruited to the AIBN where he heads the Stem Cell Engineering Laboratory and directs the Australian Organoid Facility at UQ as well as the Phenomics Australia NNAT node at UQ. He is a leader in the derivation, genome editing and disease modelling with human induced pluripotent stem cell and organoids derived from these. He was awarded the 2014 LSQ regenerative medicine prize. Professor Wolvetang serves on the editorial board of six stem cell journals; is listed inventor on four patents in stem cell research and serves as a scientific advisor to the Massimo Foundation, BrAshAT and Genetic Cures for Kids. Leveraging robotic automation and in vitro disease models his focus is to exemplify how pre-clinical testing of personalised drug and gene-therapies in human organoid models can accelerate and improve health outcomes for patients rare genetic or common acquired diseases but also for our ageing population.

Industry

​Prof Wolvetang leads a number of industry projects with national and international biopharmaceutical companies that leverage the human disease and organoid models and the robotic infrastructure established in the Wolvetang laboratory to conduct pre-clinical screening o their lead compounds.

Collaborations

Professor Wolvetang collaborates with leading clinical researchers of neurological diseases such as A/Prof Lata Vadlamudi, Prof Patrick Kwan, Prof Terence O/Brien and Prof David Coman. He works closely with leading researchers in the Ataxia Telangiectasia field such as Prof Martin Lavin and Prof Yossi Shiloh (Israel), with leaders in the gene therapy for white matter diseases such as Prof Matthias Klugmann, and virology experts such as Prof. Alexander A. Khromykh. Prof Wolvetang further manages a number of collaborations with industry partners that focus on pre-clinical organoid-based drug screening.
