Figure 4From: Human mast cells decrease SLPI levels in type II – like alveolar cell model, in vitroEffects of mast cells HMC-1 on the ability of the A549 cells to release SLPI. The SLPI release from the A549 cells was decreased in co-cultured with HMC-1 cells, compared to the A549 cells alone (p < 0.006). The most pronounced fall in SLPI production was observed after 96 hours of cell co-culture (**p < 0.01). Each point represents mean of six or five separate experiments.Back to article page
