In vitro cell changes in laser-exposed tissue.
Tissue cultures of WI 38 human embryonic lung were exposed to CO2 laser irradiation while others were maintained unexposed as controls. In the test cultures the target area demonstrated cell dehydration and distortion, consisting of nuclear and cellular elongation and cytoplasmic fragmentation. Regeneration of the cultures was gradual and incomplete.
