Biological Activity

Description	Prostaglandin E2 (PGE2, Dinoprostone) plays important effects in labour (softens cervix and causes uterine contraction) and also stimulates osteoblasts to release factors that stimulate bone resorption by osteoclasts.
In vitro	PGE2 acts via EP4 receptors on osteoclasts during the progression of OA and OA-related pain.^[1]
In vivo	PGE2 (0.3 μg/k, i.p.) significantly reduces the number of peritoneab macrophages undergoing phagocytosis of the methacrybate microbeads in rats.

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines Mice osteoclasts differentiated from bone marrow macrophages (BMMs) Concentrations 1, 10, 100, 1000, 10000 nM Incubation Time 18 h Method When BMMs differentiated into mature osteoclasts, a TRAP staining kit is used to stain mature osteoclasts according to the manufacturer s instructions, and TRAP-positive osteoclasts with 5 or more nuclei are counted. For BMM migration, BMMs (1×10⁴ cells per well) are seeded in the upper chamber of the Transwell inserts with or without inhibitors and antagonists. PGE2 is added in lower chamber. The culture medium is the same between the upper chamber and lower chamber in the Transwell. After 18 h, the cells are fixed with 4% PFA and stained with crystal violet. The cells on the bottom of the Transwell insert are used to assess migration. At least five fields of view per insert are photographed, and migrated cells are counted.
