Description: Compared to conventional materials, biomaterials in living organisms possess specific architecture and organisation: and often exhibit multiple functions. Εngineered living materials (ELMs) have emerged at the junction of synthetic biology and material science to produce materials with improved functionality because of the living organisms within them.

Funded by the European Innovation Council, the NextSkins project is inspired by the structure and function of the many layers of skin. Researchers will mimic the specialised skin arrangement to make two engineered living materials: one with a therapeutic role to treat skin diseases and one with a purpose to be used as a protective garment in sports.

Project Description: The EU-funded PRISM-LT project will use a hybrid living materials concept to create a flexible platform for living tissue manufacturing. The innovative bio-ink will contain stem cells integrated into a supporting matrix with engineered helper bacteria or yeast cells. The bioprinting process will produce a 3D patterned structure where stem cells could be induced to differentiate into different lineages. The directed stimulation of differentiating stem cells will force them to produce lineage-specific metabolites for sensing by the designer helper cells. The helper cells within the platform will then enhance localised lineage commitment to sustain differentiation stability. The project aims to implement this strategy for the development of two symbiotic materials designed for biomedical and food applications, respectively.

Project Objectives: 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.”
