The Matrix of Theseus...

The Ship of Theseus is an enduring thought experiment about the dynamics of identity. According to the story, the Athenians preserved the ship associated with the hero Theseus and his legendary voyage to Crete. As its wooden planks decayed, they were replaced with new ones, generation after generation, eventually raising a deceptively simple question: if all of the material that made up the original ship has been replaced, is it still the same ship? 

The extracellular matrix presents a biological version of this paradox. The matrix that gives tissues their architecture, mechanical properties, and biological identity is itself dynamic. Throughout life, its components are deposited, modified, degraded, and replaced. Yet tissues retain remarkable continuity despite this molecular turnover. Conversely, changes in the composition, organization, mechanics, or turnover of the matrix can reshape cellular behavior and ultimately alter tissue identity in development, aging, injury, fibrosis, cancer, and other diseases.

Set in Halifax, a city whose identity is deeply connected to the sea and its maritime history, The Matrix of Theseus uses this ancient paradox as a framework for asking a modern biological question: how does a continuously changing extracellular matrix establish, preserve, and transform the identity of tissues and organs across time, health, and disease?
