A starving man approaches you asking for help. In one hand you have a ham and cheese sandwich. In the other you have a bag of the most beautiful organic heirloom crop seeds.
Adult stem cells are the ham and cheese sandwich, available today, usable today and if he takes the sandwich he may just live to see tomorrow. Embryonic stem cells … are the crop seeds. With a lot of work and effort they may produce an abundant amount of food sometime in the distant future. But of no help today.
Which is he going to want? Which will he take if you offer both?
