Mason Shaffer was seven months old when doctors treated him for a fatal genetic bone disorder by destroying his blood and immune systems and rebuilding them with donated blood stem cells.

That's when his parents, Sarah and Marc Shaffer of Lansdowne, learned about a fairly unsung medical trend: public, nonprofit facilities that collect, store, and distribute blood from donated umbilical cords. The stem cells that saved Mason, now a healthy 5-year-old, were in cord blood.

Nonprofit cord-blood banking is a complicated, costly network, but it has been growing steadily, thanks to federal support, stem-cell research - and families like the Shaffers.

Sarah and Marc discovered that in the Philadelphia area, even if parents realized umbilical cords were more than just waste products of childbirth, there was no easy way to donate the tissue. So they established the Mason Shaffer Foundation to change that.

This month, Temple University Hospital launched a program in collaboration with the foundation and the New Jersey Cord Blood Bank to educate expectant parents and enable them to donate in a convenient way - at no charge to them or Temple. The foundation provides the educational material, and the cord-blood bank covers the collection costs, which are offset by health insurance reimbursement for transplants.

Three years ago, Lankenau Medical Center in Wynnewood became the foundation's first cord-blood donation center.

Temple, however, is expected to help fill the desperate need for a more racially diverse cord-blood stockpile. That need was recognized by the federal Stem Cell Therapeutic and Research Act of 2005, which included funding that will help underwrite the first year of Temple's program.

Of the 3,200 babies delivered at Temple each year, 65 percent are African American, and 30 percent are Hispanic.
