Remodelling1

  • New antibody-producing cell clusters can kill older cells by changing nearby survival signals

    Where this hypothesis actsMarrow survival niches receiving incoming plasmablast clusters

    What is proposedArrange stromal contacts into spatially separated islands

    With whatPhysical or surgical intervention

    HowUse micropatterned stromal cultures and marrow organoids to vary contact geometry while keeping cell numbers and total contact area matched

    Possible resultPossible preservation of old plasma cells through additional independent survival domains
