CD9 Expression by Human Granulosa Cells and Platelets as a Predictor of Fertilization Success during IVF

Figure 2

Greater surface density of CD9 on the GCs (measured as mean intensity of CD9-PE fluorescence) correlated with lower fertilization rates in mature oocytes (𝑟=−0.372,𝑃=.04). See the text for the definition of mature oocytes. The Model II regression is 𝑦=−0.27𝑥+152.8.
