Randomized trial observes clustered growth in Chinese hamster ovary cells, indicating a new in vitro assay for pertussis toxin.

The aim is to investigate the morphological response of Chinese hamster ovary cells induced by pertussis toxin.
Chinese hamster ovary cells were cultured and exposed to pertussis toxin.
The response was assessed using specific anti-toxin antibody for neutralization and heat lability tests.
The study evaluated growth patterns over time following toxin exposure.
Clustered growth patterns were observed 24 hours after exposure to pertussis toxin.
The effect was unaffected by the presence of cyclic AMP-mediated cell elongation.
Neutralization with anti-toxin confirmed the specificity of the pertussis toxin effect.

Hewlett et al. (1983) studied this question.
