<p>BACKGROUND: Intrauterine growth restriction (IUGR) is a condition where the infant fails to reach its genetic growth potential due to numerous factors. IUGR foetuses are associated with high perinatal mortality and morbidity. This study investigated if hypoxia might be involved during gestation, and whether if hypoxia may have an impact on the development of the placenta, through regulation of various angiogenic factors, such as HIF-1_, VEGF, PIGF, VEGFR-1 and CD31. METHOD: Each sample of placental tissue was stained by immunohistochemisty for HIF-1_, VEGF, PIGF, VEGFR-1 and CD31. The intensity of staining was graded and the difference between the normal term placentas and the IUGR term placentas were evaluated. RESULTS: HIF-1_ was found to be upregulated in the normal term placental tissue, and VEGFR-1 was found to be upregulated in the IUGR term placental tissue. The other antibodies did not show any significant difference and PIGF failed to show any positive staining. CONCLUSIONS: Further studies on hypoxia in IUGR would be beneficial.</p>
