Figure 5

Spontaneous formation of multinucleated giant cells in monolayers of P2Zhyper cells and HEK293 cells transfected with the P2X7 receptor. Cells were plated at the concentration of 5 × 105 cells/ml and grown for 3 d. (A–C) P2Zhyper macrophages; (D) HEK293 cells stably transfected with the P2X7 receptor. Photographs were taken with a 20× objective in A and a 40× objective in B–D. Bars: (A) 50 μm; (B–D) 25 μm.
