The Claim
The biphasic pattern of forward light scatter—initial increase followed by decrease—is not a universal signature of apoptosis in U937 cells but varies depending on the apoptotic inducer, with dehydration-inducing agents producing the increase and non-dehydrating agents producing only the decrease.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In U937 cells undergoing apoptosis, the pattern of light scatter changes differently depending on how apoptosis is triggered: agents that cause cell dehydration produce a two-phase light scatter response, while agents that do not cause dehydration produce only the second phase.

When a cell dies from certain triggers, it loses water and becomes denser, making it scatter more light at first. Later, as the cell shrinks and breaks down, it scatters less light. Other triggers kill the cell without losing water, so the light scatter only goes down from the start.
What the research says
1 studyWhen cells die in different ways, some lose water and look brighter under a light scanner at first, while others don’t lose water and never get brighter—only dimmer. This study shows it’s the water loss, not just dying, that causes the initial bright flash.
