BACKGROUND: With the development of biotechnology, repairing bone defects using tissue engineered bone has become a hot spot.

OBJECTIVE: To overview the research progress and clinical applications of repairing bone defects with tissue engineered bone. METHODS: The databases of PubMed, Springer Link, and Science Direct were retrieved for papers published from January 2000 to March 2009 with key words of “tissue engineering of bone, bone defect, and clinical applications”. The relevant papers

concerning stem cell, scaffold material, animal model, vascularization during repairing bone defects with tissue engineered bone were collected.

RESULTS AND CONCLUSION: Bone defect reparation has been a clinical challenge. The traditional autogenous bone

transplantation was the gold standard for local bone defects, which had drawback of complication. It is an ideal technique that applying allogeneic bone scaffolds without number restrictions to repair bone defects, which had possibility of rejection reaction and infection. Therefore, the applications of tissue engineered bone are the tendency. The tissue engineered bone comprised 4 key elements: bone conductive scaffolds, releasing osteogenic growth factor, loaded osteogenic potential cells, as well as vascularization. Thus, the factors involved in osteanagenesis and its relations, as well as animal model studies should be evaluated during bone defects reparation. There have been shown positive roles and considerable development prospects of tissue engineered bone, but many issues have to be solved before the clinical applications.

摘要

背景:隨著生物技術的興起,以生物材料來制作移植替代物的組織工程學正在不斷地發(fā)展,因此組織工程骨修復骨缺損也成為當前的研究熱點。

目的:概述國際上關于骨組織工程研究的現(xiàn)狀及臨床應用的進展。

方法:應用計算機檢索PubMed數(shù)據(jù)庫、Springer Link數(shù)據(jù)庫、Science Direct數(shù)據(jù)庫2000-01/2009-03文獻,檢索詞為 “tissue engineering of bone,bone defect,clinical applications”。選擇與組織工程骨修復骨缺損相關的種子細胞、支架材料、動物模型、血管化和臨床應用的文章, 無論觀察對象為人或動物均納入檢索標準。

結果與結論:骨缺損的修復是臨床上的難題之一, 傳統(tǒng)吻合血管的自體骨移植是治療局部骨缺損的金標準,但是其存在供骨區(qū)并發(fā)癥及數(shù)量有限的缺點。而無活性的異體骨雖然不受數(shù)量的限制,但是存在排異和傳染疾病的可能。因此利用組織工程技術構建組織工程骨是修復骨缺損的趨勢。組織工程骨包含具有骨傳導性的支架、釋放誘導成骨的生長因子、負載具有成骨潛能的細胞及組織工程骨血管化或充足的血供4個關鍵元素,因此要準確地評估組織工程骨修復骨缺損的作用,需要進一步理解參與骨再生的各種因素及其相互作用,同時還要在標準化動物模型研究中衡量積極因素和可能的有害影響。骨組織工程在實驗研究領域已經顯示出了積極的作用和相當大的發(fā)展前景,但在進入臨床應用以前還有很多問題等待解決。 關鍵詞:組織工程骨;骨缺損;臨床應用;修復;血管化;種子細胞 doi:10.3969/j.issn.1673-8225.2010.24.027

0 背景 由創(chuàng)傷、炎癥、腫瘤的外科治療所導致的骨缺損特別是長段骨缺損,是除了由骨折所致的骨不連外,,引起功能喪失并影響生活質量的主要原因。目前傳統(tǒng)自體松質骨移植是治療局部骨缺損的金標準,但是其存在不可否認的局限性,如供骨區(qū)損傷、術后并發(fā)癥和治療費用等問題,更重要的是來源與數(shù)量的限制。異體

骨移植則不受形狀與數(shù)量的限制,可達到即時的骨量要求,其骨愈合過程與傳統(tǒng)的長段自體移植骨基本類似。但是異體骨經各種滅菌處理,缺乏自身成骨作用,骨愈合過程緩慢且多存在不同程度的排斥反應,因此效果欠佳。隨著生物材料學的興起,以生物材料來制作移植替代物的組織工程學正在不斷地發(fā)展,因此組織工程骨修復骨缺損也成為當前的研究熱點。
