2012年8月16日,Paolo Macchiarini團隊在Biomaterials(IF=14)在線發表題為“Viability and proliferation of rat MSCs on adhesion protein-modified PET and PU scaffolds”的研究論文,該研究表明,PET和PU墊都符合ECM纖維的尺寸,是仿生支架,并且由于靜電紡絲過程提供的高表面積比,使它們本身適合細胞附著和增殖,而無需任何額外的涂層。
但是,在2024年1月4日,該文章被撤回,主要原因是偽造/捏造數據。
另外,2023年10月28日,Lancet 撤回了“Clinical transplantation of a tissue-engineered airway”及“The first tissue-engineered airway transplantation: 5-year follow-up results”2篇文章,主要原因是偽造/捏造數據(點擊閱讀)。
據了解,Macchiarini被認為是再生醫學領域的先驅,使用生物和合成支架植入患者自身的干細胞作為氣管移植,Paolo Macchiarini從2010年起擔任瑞典卡羅林斯卡醫學院臨時合同的訪問研究員。Macchiarini被指控研究不端行為和不道德的實驗性手術,即使對相對健康的患者也是如此。接受其中一項合成氣管移植手術的8名患者中有7名已經死亡。卡羅林斯卡學院于 2016 年解雇了Macchiarini 。瑞典中央倫理審查委員會裁定他犯有研究不端行為,該委員會要求撤回卡羅林斯卡研究的六篇論文[包含先前發表的2篇Lancet(Tracheobronchial transplantation with a stem-cell-seeded bioartificial nanocomposite: a proof-of-concept study及Engineered whole organs and complex tissues) ]。 丑聞發生后,瑞典成立了國家研究不端行為評估委員會。Macchiarini 在 2019 年缺席的情況下被意大利法院判處有期徒刑。
