Telling states apart1

  • Tissue deformation makes restored skin flexibility appear to promote abnormal cell spread

    Where this hypothesis actsIn tissue deformed by loading after compliance restoration

    What is proposedDistinguish actual clone growth from deformation-induced increases in projected area

    With whatInstrument or assay

    HowUse tissue-following three-dimensional registration, absolute lineage-labeled cell counts, paired loaded/unloaded measurements, and fixed-tissue deformation controls

    Possible resultExpected disappearance of the apparent increase in clone size after accounting for tissue deformation
