Table 1 Effect of BCP and CPPD on macrophage survival

From: Inflammatory microcrystals induce murine macrophage survival and DNA synthesis


No. of cells (×10-4)


  2.0 ± 0.2


12.7 ± 1.1


   4.7 ± 0.2a

  1. BMMs (13.0 ± 0.6 × 104) from which CSF-1 had just been removed were cultured in RPMI/10% FBS, in the absence or presence of BCP (500 μg/ml) or CPPD (500 μg/ml). After one day, cells were washed twice to remove cystals and recultured in RPMI/10% FBS for a further two days. Then the number of viable cells was determined by hemocytometer counting and trypan blue exclusion. Data are mean values ± SEM from triplicate cultures and are from a representative experiment that was repeated once. aP < 0.05 in comparison with untreated group (Student's two-tailed t-test).
