На спине крысы вырастили человеческое ухо

Используя стволовые клетки, ученые вырастили ухо человека на спине крысы. Эксперимент был проведен исследователями из Университета Токио (University of Tokyo) И Университета Киото (Kyoto University) под руководством Томаса Сервантеса (Thomas Cervantes).

Исследовательской группе из Больницы Морристона (Morriston Hospital) под руководством Яйна Уитейкера (Iain Whitaker) с помощью трехмерной печати удалось создать хрящевую ткань, подходящую для пересадки.

Авторы использовали индуцированные плюрипотентные стволовые клетки, с помощью которых они сначала вырастили хрящевой каркас, которому в дальнейшем придали форму, соответствующую ушной раковине. После этого каркас поместили под кожу крысы, где за двенадцать недель сформировалось ухо длиной около 5 см.

Исследователи считают, что с помощью такой методики они смогут выращивать отсутствующие или поврежденные ушные раковины и пересаживать их пациентам. Они не исключают того, что выращенное таким образом ухо, пересаженное ребенку, будет увеличиваться в размерах по мере взросления пациента. Они планируют перейти к клиническим испытаниям своей методики в течение ближайших пяти лет.
