The lack of realistic in vitro organ models that faithfully represent in vivo physiological processes is a major obstacle affecting the biological and medical sciences. The current gold standard is animal experimentation, but it is increasingly evident that these models mostly fail to recapitulate human physiology. Moreover, animal experiments are controversial, and it is a common goal in the scientific community to minimise the use of animals to a strictly necessary minimum. 

The emergence of stem cell-engineered organ models called organoids represents the only viable alternative to animal research. However, current organoid technology is yet to produce the larger physiologically relevant organ models that the medical sciences need. Specifically, current organoids are too small, not vascularised and lack the 3-dimensional organisation found in vivo. 

In this interdisciplinary project, we aim to challenge all these limitations using the recently developed gastruloid technology guided by cutting-edge bioengineering and artificial intelligence. 

Gastruloids are formed by initiating the very early developmental processes and develop along a highly coordinated three-axial process that closely resembles mammalian embryogenesis. They can establish several organ precursors simultaneously, thus constituting relevant improvements over conventional single-tissue organoids. 

To harvest the potential of gastruloid technology, we will first implement extensive sequencing and imaging experiments to optimise the developmental trajectory of gastruloids for organ inductions. We will then build these datasets into a multimodal data matrix to identify gastruloid candidates for cardiovascular and foregut development. Candidates with substantial vasculogenesis will be chosen for later vascularisation by anastomose with endothelial cells.”
