Lab-on-a-Chip in the Extracellular Vesicle Research Group (A.Ābols lab)

The main goal of the group is to study potential applications and modifications of extracellular vesicles (EVs) from different sources, such as mesenchymal stem cells (MSC) and microbiome in cancer treatment using Lab-on-a-Chip (LoC) including Organs on Chip (OOC) technology. Therefore, we have an interdisciplinary research direction in collaboration with the Laboratory of prototyping from ISSP with expertise in microfluidics and biosensors. Both EVs and LoC technology are currently very active fields of research worldwide. EVs hold great promise in diagnostics and treatment, including cancer. However, the issues in EV methodology significantly slow down the development of the field. LoC technologies based on microfluidics and biosensors could substantially improve this situation.

Our purpose is to personalise OOC developed in collaboration with Laboratory of prototyping from ISSP using patient samples for engineered or modified EV testing for cancer treatment purposes, that could serve as a tool in personalised medicine in future.
