In multicellular organisms, apoptosis and subsequent microparticle shedding play a key role in homeostasis. Having long been considered as << cellular dust >>, microparticles released in biological fluids upon cell activation or apoptosis appear as multifunctional bioeffectors involved in the modulation of key functions including immunity, inflammation, hemostasis and thrombosis, angiogenesis. MP constitute reliable markers of vascular damage, accessible to biological detection whilst the cells they originate from remain sequestered in tissues or are promptly submitted to phagocytosis.
