Mechanics as a cancer phenotype

Cell biomechanics tracks with cancer cell function, which makes mechanical measurement a route to classifying tumor cells by behavior rather than by marker alone. Published work in our library includes machine-learning classification of cancer subpopulations differing in drug resistance or malignancy from their particle-uptake patterns, and force measurement approaches for multicellular clusters with irregular geometry.

Invasion and mechanics are studied together in the library as well: 3D co-culture systems that monitor cancer cell invasion alongside T-cell interaction, and cytoskeletal-tension studies showing that inhibiting cellular contraction dramatically slows microtissue self-assembly — evidence that the forces cells generate shape 3D tissue behavior directly.

Why 3D changes the measurement

Tumor cells grown as 3D structures acquire multicellular resistance that mimics the chemoresistance of solid tumors; one library study found that a drug combination which nearly eliminated cells in monolayer largely failed against the same cells as spheroids. Measuring mechanics in 3D therefore reports on a state that flat culture does not reproduce.

The 3D Petri Dish® supports this work by producing arrays of size-matched spheroids: cells settle into the recesses of a cast, non-adhesive agarose gel and self-assemble through their own adhesion, with size set by seeding number. Molds are reusable (guaranteed 12 uses) and autoclavable at 121°C.
