The uterine environment of obese mothers programs the cellular make-up of their offspring to accumulate extra fat that could lead to insulin resistance.

Kristen E. Boyle, Assistant Professor at the University of Colorado School of Medicine and her team took stem cells from donated umbilical cords of the babies of normal-weight and obese mothers and grew them into fat and muscle cells in the lab.
They found a 30 percent higher fat content in both types of cells in the offspring of mothers who were obese at their first prenatal visit, compared to the cells of offspring of normal-weight moms.
They are continuing to evaluate the data to determine if these cells likewise show evidence of altered metabolism.
