Quantitative analysis of number and intensity of SphK1 positive AMC. Significantly increased numbers of SphK1-positive AMC (co-expressing OX-42) are evident in 1 h after hypoxia (A). The intensity of SphK1 immunofluorescence is increased significantly at 15 min and 1 h compared with that 6 h after hypoxia and that of control (B). The data are presented as mean ± S.E. Control vs Hypoxia, * P < 0.05, ** P < 0.01
