Optimization of phorbol myristate acetate (PMA)‐induced apoptosis in healthy subjects (n = 5) in comparison to spontaneous apoptosis of neutrophils. Half the samples treated with PMA while the other half was left without PMA. Late apoptosis of neutrophils positive for both Phi‐Philux and propidium iodide staining was checked in various time points and PMA induced cell death has been shown (P = 0.034, Mann–Whitney U‐test). SLA, spontaneous late apoptosis.
