Figure 2From: IGFBP-4 and −5 are expressed in first-trimester villi and differentially regulate the migration of HTR-8/SVneo cellsEffects of IGF-I, IGF-II, IGFBP-4 and IGFBP-5 on migration of HTR-8/SVneo cells. Values are mean ± standard error of the mean, and values with different superscript letters are significantly different according to Tukey’s HSD test (overall variation among treatments: F6, 249 = 38.11, P < 0.0001, N = 24–62 per treatment).Back to article page
