The Claim
Cholesterol depletion by methyl-β-cyclodextrin increases the diameter of membrane ruptures during hypo-osmotic shock in human HeLa cells and red blood cells, indicating that cholesterol loss reduces the membrane's resistance to pore expansion independent of cytoskeletal constraints.

Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Removing cholesterol from human cell membranes using methyl-β-cyclodextrin causes larger tears in the membrane when cells are exposed to low-salt conditions, showing that cholesterol directly limits how much the membrane can stretch before rupturing, regardless of the internal skeleton.
See the scientific wording
Cholesterol depletion by methyl-β-cyclodextrin increases the diameter of membrane ruptures during hypo-osmotic shock in human HeLa cells and red blood cells, suggesting that cholesterol loss reduces the membrane’s resistance to pore expansion, independent of cytoskeletal constraints.
When cholesterol is removed from the cell membrane, the membrane becomes tighter and less able to stretch without tearing. This makes it easier for large holes to form when the cell swells in water, and the holes grow bigger because the membrane can't hold itself together as well.

1 studyStudy: Cholesterol Depletion by MβCD Enhances Cell Membrane Tension and Its Variations-Reducing Integrity
When scientists remove cholesterol from cell membranes, the cells burst into bigger holes when placed in salty water—like a balloon popping wider when its rubber is weaker. This happens even if the cell’s internal skeleton is disabled, proving cholesterol itself helps keep tears small.
