Cellular chirality
WebDec 27, 2024 · We asked this question in the context of growing cellular aggregates and found that chirality could directly affect fitness through a pattern-formation mechanism. Our results show that, depending on the growth conditions, it could be advantageous for a cell to increase its chirality or to switch its handedness relative to that of the ancestral ...

WebJun 27, 2011 · Cellular LR asymmetry on micropatterned rings is established by mechanisms involving boundary effects. (A) Cells on a ring “sense” the z axis through attachment to the substrate and the x axis through the ring boundaries. The cell alignment bias of the y axis (dash red lines) creates the observed cellular chiral behavior or LR …
WebAug 21, 2015 · When compared to individual cell analysis, the nuclear alignment can also be used to determine the chirality of multicellular rings, as both demonstrate a similar bias, with 57.9% (22 out of 38) of the cellular rings demonstrated a cellular CCW bias, and 50% (19 out of 38) having a nuclear CCW bias.
