To the Editor:
The article by Wagner et al was very encouraging on the potential use of human umbilical cord blood. On page 1879, 1st column 2nd paragraph, there appears a sentence that raises considerable legal, ethical, and medical questions, similar to what occurred in our studies approximately 25 years ago. The statement, which read, “However, recent alterations in the technique of cord blood collection (eg, earlier clamping of the cord) routinely yield twofold to fourfold larger harvest (ie, 150 to 300 mL),” raises considerable concern.
