From: The role of EMMPRIN/CD147 in regulating angiogenesis in patients with psoriatic arthritis
Co-culture enhances the secretion of some pro-angiogenic factors. HT1080 (4 × 105 cells) were co-cultured with either MM6 (4 × 105 cells), with and without the addition of TNF-α (1 ng/mL) and compared to each single culture. Supernatants were collected after 48 h of incubation and the concentrations of a CD147 (n = 6), b VEGF (n = 6), c MMP-9 (n = 6), and d Tsp-1 (n = 6) were determined by ELISA. e The CD147/Tsp-1 ratio was calculated for each repetition
