Project Background:

Drug discovery is known to be a long and expensive process with very low success outcomes. The whole process usually develops over three phases: i) synthesis of the drug molecules, ii) preclinical animal trials, and iii) human clinical trials. Preclinical animal trials have shown crucial limitations in the past years, as caused by the wide interspecies gaps between animals and humans. This often translates into wide unreliability in animal trials’ outcomes, with huge losses in pharmaceutical research and development programs.

The use of human-derived in vitro/ex vivo models has opened new horizons in this field, by preserving patients-specific features and reproducing physiological and pathological scenarios more reliably1,2.

The urgency in establishing novel therapeutic strategies is evident in the field of liver disease, as shown by the constant rise in cases3 and the complex multifactorial nature of hepatic pathologies.

Precision-cut tissue slices (PCTSs) and organoids have the potential to overcome these challenges. PCTSs are biological tissue sections that retain organs’ features, in either their physiological or pathological state, whilst organoids are 3D cellular aggregates with wide scientific and clinical applicability. These models have generated great interest from scientific and healthcare institutions, showing the potential to reduce (and replace) preclinical animal trials.

Research aims:

This doctoral project concerns the development of an automatised platform devoted to the derivation of PCTSs and organoids from patient-derived surgical samples. This will concern the combination of mechanical components, electronic circuitry, and automatised modules. The platform will then be used to assess the efficacy of novel drug candidates by integrating biological and machine learning approaches.

The project aims at establishing a multidisciplinary approach to tackle current shortcomings in drug discovery processes by adopting a multifaceted perspective. If successful, this work will establish novel drug discovery pipelines that can be further expanded to a wide array of pathological scenarios.
