Stimulation of murine chondroitin sulfate E containing mast cells (E-MC) in vitro either by thrombin or immunologically resulted in a rapid formation of inositol phosphates (IPs). Increase in all of the three IPs (IP1 IP2 and IP3) could be detected 20 s after stimulation. The depletion of Ca2+ from the medium resulted in more than 80% reduction in β-hexosaminidase release from either thrombin or IgE antigen stimulated cells. However, both thrombin and IgE antigen increased the formation of IP3 under these conditions independent of the presence of extracellular Ca2+.
