Help please! is banking umbilical cord blood old news or the way of the future?

Maybe public banks: Umbilical cord banking became more popular as stem cell transplants became more common for cancer and related conditions. While public banking may have value, the utility of private cord banks is questionable, due to cost, long-term viability concerns, insufficient quantities for individual use, and risks of using one's own cells. Most experts and medical societies recommend against private banks.
