Bryan G can't eat enough food to make himself grow. poor nutrition makes him so tired he has no strength to play ball or walk through an airport without a wheelchair. Bryan suffers from severe, chronic Crohn's disease. parts of his small intestin, usually half an inch in diameter, are so diseased they are only as wide as a piece of pencil lead For Crohn's victims, it is nearly impossible to digest and process food, Bryan's disease is so severe he has recently been approved to recieve, experimental stem cell transplant. Stem cell can be grown from adult tissues. but these stem cells do not seem to last for long, nor can they develop into wide variety of cell type. Stem cells often come from embryos that are "left over" from in vitro fertilization-artificial fertilization. they can also be taken from aborted fetuses. If he has the transplant, Bryan would be the eleventh person in the USA to receive a transplant for Crohn's disease. the previous ten patients no longer suffer from any symptoms of Crohn's 역시 각문장과의 관계는 없구요. stem cells라는 내용의 글을읽다가 도저히 매끄럽게 해석되지 않아서 올린것입니다. 틀린문자들은 다 고쳐놨습니다. ㅠ.ㅠ
