Rewolucyjna biodrukarka

Mamy wreszcie drukarkę 3D, która może przyspieszać rekonwalescencję pacjentów z ciężkimi oparzeniami, ranami cukrzycowymi oraz innymi rozległymi i wolno gojącymi się uszkodzeniami skóry.

Naukowcy z amerykańskiego Wake Forest Institute for Regenerative Medicine stworzyli mobilną biodrukarkę, która korzystając z komórek pacjenta, może bezpośrednio na jego ranę drukować nową skórę.

Wspomniane urządzenie jest pierwszym na świecie, które potrafi drukować skórę w dwu warstwach i to na otwartej ranie.

Główny autor pracy Sean Murphy wyjaśnił, że wyjątkową zaletą systemu jest to, że potrafi skanować rany i umieszczać komórki tam, gdzie są niezbędne, by uformowała się nowa skóra.

Prototypy niezwykłej drukarki powielały większe warstwy skóry, które potem przeszczepiało się do urządzeń mobilnych.

 

Namnaża zdrowe komórki skóry

Urządzenie można dowozić do hospitalizowanego pacjenta, by pracowało bezpośrednio na nim.

Tym, co odróżnia je od poprzedników jest sposób, w jaki pracuje. Najpierw pobiera próbkę zdrowej skóry celem wyizolowania dwu warstw komórek, które będą namnażane. Następnie, zamiast od razu kłaść gotową warstwę skóry, skanuje ranę, by stworzyć jej mapę topograficzną.

Jak donoszą media, chociaż technika, nad którą pracuje Wake Forest naśladuje naturalną strukturę skóry, urazy goją się o wiele szybciej.
