Viaggio interstellare nel microcosmo cellulare | Ludovica Cacopardo | TEDxVicenza

Quick Overview

Ludovica Cacopardo details how her team applies principles from physics, specifically modeling cell migration like gravitational attraction in spacetime, to develop more effective, non-animal-based testing methods for drug toxicity and regenerative medicine using in-silico simulations and advanced microscopy.

Key Points: Cacopardo's research uses physics models, comparing cell movement to gravitational effects on spacetime, to understand cellular behavior in complex environments like tissue. The team uses in-silico simulations, cell culture on viscoelastic substrates (using silicone decouplers), and mechanical testing (AFM, UTM) to gather data. The goal is to predict cell migration paths, such as cells moving toward or away from clusters ('planets' moving around a 'star' cluster), which is vital for understanding tissue dynamics and disease progression like tumor metastasis. The research aims to replace animal testing by creating highly predictive, advanced in-vitro models that mimic the physical properties of biological environments. Cacopardo introduced her startup, Interstellar, inspired by the Portuguese scientist whose work demonstrated that the behavior of cells, like planets, is influenced by the mass/density of surrounding structures (clusters). The team observed that cells in denser areas (like the honey example) move slower, while cells in less dense areas move faster, mirroring gravitational effects on trajectories. The ultimate aim is to improve drug screening and regenerative medicine by creating predictable, non-animal models that account for complex mechanical cues.

Context: Ludovica Cacopardo, a bioengineer, presents her work at TEDxVicenza, focusing on bridging the gap between fundamental physics modeling and cellular biology. She discusses the complexity of the cellular environment, drawing analogies between gravitational physics (like planets orbiting massive objects) and how cells interact, move, and form structures within tissues, particularly in contexts like tumor progression and drug toxicity testing.
