Kidney Development: During gestation the nephrons (functional units of the kidneys) are formed; once development is completed, no new nephrons are formed for your lifetime. Therefore, it is essential for life-long renal health that the number of nephrons formed are optimised during fetal life.
Chronic Fetal Hypoxia: A low oxygen supply to the developing fetus occurs in numerous conditions during pregnancy, such as pre-eclampsia and placental insufficiency. This results in growth restriction of the fetus, including impaired development of the kidneys. Using a large animal (ovine) model, current research is focussed on investigating the long-term impact of fetal hypoxia on the kidneys. Furthermore, maternal Vitamin C administration is being investigated as a possible treatment to ameliorate the effects of fetal hypoxia on kidney development.
