The story from today's UK Guardian: "British team grows human heart valve from stem cells."
But is it just any kind of stem cells? Was it from the most discussed and controversial type of stem cells: embryonic?
You have to read 10 paragraphs into the story to find out it was adult stem cells.
By using chemical and physical nudges, the scientists first coaxed stem cells extracted from bone marrow to grow into heart valve cells. By placing these cells into scaffolds made of collagen, Dr Chester and his colleague Patricia Taylor then grew small 3cm-wide discs of heart valve tissue.
Despite the hysterical rush of the "death culture" to use human embryos for medical research, embryonic stem cells have yet to help a single human being. Meanwhile, adult, amniotic and umbilical cord blood have already helped many people.
When people hear the term "stem cell research," most think of embryonic stem cell research. Was this a simple omission on the part of the Guardian reporter, or a "selective" omission?
