Cooperating dangerous cells in breast tissue

Estrogen re-exposure may eliminate dangerous breast clones through abnormal spindle geometry

Where this hypothesis actsAfter prolonged estrogen deprivation, in clones with centrosomal abnormalities

What is proposedEliminate clones with centrosomal abnormalities through estrogen re-exposure

With whatSmall molecule

HowRe-expose estrogen-deprived cells to estrogen to drive multipolar divisions; assess irreversible lineage loss after washout and replating

Possible resultPossible irreversible loss of abnormal clones while neighboring cells with normal centrosomes continue dividing

Estrogen may eliminate dangerous breast clones when cooperative support falls below a threshold

What is proposedReduce local cell density below the cooperative persistence threshold

With whatPhysical or surgical intervention

HowUse micropatterned organoids to dilute cooperating cells, replacing removed cells with noncooperating epithelial cells while keeping intracellular estradiol exposure matched
