Stanniocalcin-1 Regulates Extracellular ATP-Induced Calcium Waves in Human Epithelial Cancer Cells by Stimulating ATP Release from Bystander Cells
Figure 2
Mechanically Injured Cells Released and Responded to Extracellular ATP.
A) Mean ATP content of conditioned media from control or mechanically stimulated A549 monolayers. RLU, relative luciferase units. Error Bars = SD. * = p<0.05. n = 3. B) ATP (50 µM) alone was added to confluent Fluo-4 labeled A549 cells (vertical line). Calcium response was measured by fluorescent microscopy. n = 4 movies.
