Table 2 Release of PGE2 into the supernatant of cultured rat chondrocytes

From: Cyclooxygenases and prostaglandin E2 receptors in growth plate chondrocytes in vitro and in situ – prostaglandin E2dependent proliferation of growth plate chondrocytes

Incubation time PGE2 (μg/ml) Proliferation status
0 120 ± 20  
2 days 530 ± 270a Rapidly proliferating
6 days 150 ± 30 Slowly proliferating
  1. Chondrocytes were seeded in culture plates and fresh medium was added. At different time points supernatant was collected and analyzed for prostaglandin E2 (PGE2) content (n = 6; ap < 0.01 versus day 0).
