INTRODUCTION
The present studies initially show the induction of dwarf forms from the disrupted cells of the large unicellular organism, Stentor coeruleus. The dwarf cells placed in a toxic solution showed evidence of cell death. Within minutes a morphological replicate of the cell separates and subsequently fades.
METHODS
Dehydration of the commercially available Stentor media in deep well slides (n = 9) caused disruption of the large cells. Rehydration with sterile media allowed formation of mobile dwarf forms. The latter (n = 9) placed in a toxic solution lost mobility and showed evidence of cell death, i.e., apoptosis. Deep well slides (n = 9) containing sterile Stentor media were used as controls.
RESULTS
In the slides following dehydration/ rehydration of the living Stentor media, 7of 9 showed mobile dwarf cells compared to 0 of 9 with the sterile media alone, p < 0.05). Within 8-12 min, the stationary dwarf cell progressively released a morphological replicate of the dead cell which contained entrapped bacteria. Subsequent fading of the replicate allowed dispersion of the bacteria.
CONCLUSION
These findings provide evidence that cell death indicated by apopotosis (blebbing) is followed by a sequence consisting of the progressive separation of a replicate image which is initially visible then becoming a progressively non-visible, faded image.
