Figure 4. VEGF protein in room air controls (RA) and in 50/10 OIR model

VEGF protein measured by ELISA in RA control animals and in 50/10 OIR model animals that had 1 cycle of 24 h of 50% oxygen followed by 24 h of 10% oxygen (P2) and 7 cycles of 24 h of 50% oxygen followed by 24 h of 10% oxygen (P14). Results are means of four samples; error bars are standard deviations. An asterisk ("*") indicates p<0.03 compared to control (t-test); double asterisks ("**") indicate p<0.004 compared to control (t-test).
