these findings demonstrate dissociation of agonist-induced ca2+ entry from intracellular ca2+ pool refilling and thereby provide strong support for the recently modified version of the capacitative ca2+ entry model according to which influx into the cytoplasm occurs directly across the plasma membrane and does not require a specialized cation channel directly linking the extracellular space and the intracellular ca2+ stores .
