title: Release of 6-keto-prostaglandin F1 alpha and thromboxane B2 from mouse peritoneal macrophages during their adhesion and spreading on a glass surface.
abstract: The release of 6-keto-prostaglandin F1 alpha (6KF1 alpha) and of thromboxane B2 (TXB2) from cells were investigated using mouse peritoneal exudate cells (PECs) and non-cultured peritoneal macrophages. They were prepared by adhesion to glass dishes and incubated for 1 hr at 37 degrees C in 5% CO2 in air. Both the percentage of spreading macrophages and the release of 6KF1 alpha and TXB2 increased in proportion to the incubation time. 6KF1 alpha and TXB2 were released from the macrophages, not from the non-coated glass dishes, the spreading of macrophages was hardly detected and lower amounts of 6KF1 alpha and TXB2 were released from these cells compared with cells incubated in non-treated glass dishes. These findings suggest that adhesion with the correlated spreading of macrophages on glass dishes serve as a considerable physical factor for the release of 6KF1 alpha and TXB2.
