Building a Human Heart Valve 
The World Heath Organization estimates that some 600,000 people around the world will need replacement heart valves within the next three years. British scientists delivered those patients some hopeful news: A team of researchers led by Dr. Magdi Yacoub of the Imperial College of London saw 10 years of work come to fruition this spring, when they grew bone marrow stem cells into functioning human heart-valve tissue. Yacoub hopes that the tissue can be grown into the shape of a heart valve using a special collagen scaffolding. Yacoub’s advancements build on the ongoing efforts of scientists around the world to grow new heart valves and other body parts. If Yacoub’s tissue holds up in animal trials, he estimates it could be used in human heart-valve transplant patients within 3 to 5 years.
По оценкам Всемирной организации здравоохранения, около 600 000 человек во всем мире будут нуждаться в замене сердечных клапанов в течение следующих трех лет. Британские ученые доставили этим пациентам несколько обнадеживающих новостей: команда исследователей под руководством доктора Магди Якуба из Имперского колледжа Лондона увидела, что этой весной увенчались успехом 10 лет работы, когда они вырастили стволовые клетки костного мозга в функционирующую ткань сердечного клапана человека. . Якуб надеется, что ткань можно вырастить в форму сердечного клапана, используя специальные коллагеновые каркасы. Достижения Якуба основаны на постоянных усилиях ученых всего мира по выращиванию новых сердечных клапанов и других частей тела. Если ткань Якуба выдержит испытания на животных, по его оценкам, ее можно будет использовать у пациентов с трансплантацией сердечного клапана в течение 3-5 лет.
