^aTwo non-PE and one PE samples had missing data on the initial total nucleated and mononuclear cells. Different samples had missing data on stem cell populations measured in the sorted mononuclear cells.

^bCell counts × 10⁶ per milliliter of umbilical cord blood.

^cCell counts per 10³ mononuclear cells.
