mortality/aging
• mice die within the first day of birth

hematopoietic system
• upon activation with PAR4p or convulxin, platelets derived from chimeric mice fail to sustain calcium ion spike observed in wild-type cells, and this effect is more prominent at low doses of the agonists
• following treatment with thapsigargin, platelets derived from chimeric mice fail to exhibit an influx of extracellular calcium ions in the presence of extracellular calcium ions unlike wild-type cells
• calcium ion-dependent platelet activation, as determined by integrin activation and P-selectin expression, of platelets derived from chimeric mice is impaired at low doses of agonist
• however, platelet aggregation and thrombus formation of platelets derived from chimeric mice are normal

homeostasis/metabolism
