Pseudoapoptosis can be defined from multiple viewpoints, with an underlying premise of the differences in cellular processes and states relating to apoptosis. Pseudoapoptosis can be referred to as an apoptotic-like cellular state that can be readily reversed, or as a process that induces rapid apoptosis through the introduction of drugs such as bleomycin.
Pseudoapoptosis has been used to define a cellular state closely resembling the initial stages of apoptosis, but asserts a readily reversible state of which a cell can resume normal cellular function. Chemical and morphological changes a cell may undergo associated with pseudoapoptosis include blebbing, plasma membrane lipid asymmetry, cytoskeleton alterations, changes in mitochondrial function, and increased concentration of cytosolic calcium. Regardless of these cellular alterations, pseudoapoptotic cells reverse these changes to resume normal cellular process.
Pseudoapoptosis has also been used in some instances when describing an accelerated, drug induced apoptotic pathway by bleomycin. Cell death occurs as it would in apoptosis, but certain apoptotic mechanisms are not utilized when in the presence of bleomycin.
