Intracellular Calcium influx. Representative variation of intracellular Calcium influx in differentiated MSC treated with AMPA (40 μM, ---×---), glutamate (100 μM, 
) or CNQX (10 μM, 
). Results are expressed as fluorescence intensity at 4 second-intervals using the Fluo-4 NW tracer. Agonists (AMPA or Glutamate) and antagonist CNQX were compared with spontaneous level of calcium influx in presence of Ca2+ alone (
).
