 Apoptosis - Wikipedia, the free encyclopedia
It must be advised, however, that the apoptotic pathways that have been summarily described are subject to regulatory mechanisms, and that there is not a one-to-one relationship between the reception of TNF or FasL and the complete execution of an apoptotic pathway.
Beyond the physiological importance, understanding these patterns will be relevant to maintaining the vitality of cells used for cell therapy.
Wang and his team identified and reconstituted the mitochondrial pathway to apoptosis (see Biochemical execution, above).

Could the authors please clear this point up for the readers, and if a biphasic response is present show error bars to support this statement or make a statemnt about the error present in their system.
I believe the authors mean biphasic in the kinetic sense, but they may be reffering to biphaisc in the mechanistic sense.
Second, the authors state that there is a biphasic response demonstrated in figures 2 and 3, but I do not see two peaks or anything that resembles another peak.
