TPLH has assembled a colony of baboons between 0 and 25 years of age (0 to 100 human equivalent). In addition to studies on postnatal animals across the life-course, the TPLH NICHD Program Project Grant, in year 22, supports studies on mothers and their fetuses throughout pregnancy. Several well-established, funded investigator groups are collaborating in either individual projects or multidisciplinary, multi-institution projects studying these animals.

We have considerable experience in conducting long-term in vivo physiological studies using free moving animals on a tether system to study endocrine, cardiovascular, and metabolic endpoints. We have an extensive archive of frozen and fixed tissues from baboons from 0.5 gestation to term and across the life-course.

We are developing a multi-institution, multidisciplinary project to develop the power of this unique nonhuman primate colony to evaluate effects of the following on the aging process:

  1. health of mothers and sires before pregnancy;
  2. outcomes of developmental programming challenges, such as sub-optimal maternal nutrition (under- and over-nutrition), maternal stress, and exposure to environmental pollutants and obstetric pharmacological agents administered to mothers in pregnancy and lactation;
  3. normal life course aging.

If you have an interest in participating, contact the Director, Peter W Nathanielsz, at .
