Metastasis causes 90% of cancer deaths, yet remains incredibly hard to study because lab models can't accurately replicate tumour spread between human organs.
A new approach could finally change this.

Are research tools getting too complex for their own good?
MPSs could transform drug discovery, but many are too costly, complex, or specialised for everyday labs.
We believe that better science starts with:
✔️ Simpler workflows
✔️ Realistic costs
✔️ Usability first

We know more about curing diseases in animals than in humans. With 90% of drugs failing in human trials after animal testing, it’s clear: animal models are outdated, inefficient, and unethical. Human-relevant systems like #QuasiVivo can save human lives and reduce animal testing.
