中文摘要 在軟骨組織工程中,細胞、細胞支架和刺激是三個重要的組成。骨軟骨病是一種軟骨內骨化在生長板上的病變,因而導致骨關節炎或退化性軟骨疾病。連續式被動運動是物理性刺激,它具有刺激細胞在關節缺陷處之增生。為了更加了解連續式被動運動如何在全層軟骨缺陷生成修復之效應,本研究使用兔子模型經由評估巨觀、電腦斷層掃描以及組織學染色。三釐米大小的缺陷分別在髕骨溝和內側髁各代表高承重區和低承重區。聚乳酸甘醇酸是生醫可降解高分子,它已經被美國食品及藥物管理局所認可使用且廣泛地應用於生醫材料產品中。在本研究中,聚乳酸甘醇酸經由鹽析法製備圓柱型多孔洞細胞支架。細胞支架被植入於骨軟骨缺陷之實驗組。每組三隻兔子治療於每一組,觀察時間點為:有/無聚乳酸甘醇酸結合固定膝關節在術後四週;有/無聚乳酸甘醇酸結合固定膝關節在術後十二週;有/無聚乳酸甘醇酸結合自由活動在術後四週;有/無聚乳酸甘醇酸結合自由活動在術後十二週; 有/無聚乳酸甘醇酸結合連續式被動運動在術後四週; 有/無聚乳酸甘醇酸結合連續式被動運動在術後十二週。結果顯示在術後四週,聚乳酸甘醇酸細胞支架提供力學性質在內側髁。雖然組織學分數在固定膝關節結合聚乳酸甘醇酸細胞支架組最高,但異常骨頭增生被發現且限制了關節角度。術後十二週,細胞支架的修復在內側髁經由連續式被動運動結合細胞支架組顯著性高於只有連續式被動運動(p = 0.048)。總結,關節軟骨之功能和細胞分化與增生在修復成透明軟骨扮演了重要角色。本研究顯示連續式被動運動結合細胞支架組可以誘發軟骨和硬骨分化在修復處,此方法也許可應用於臨床和軟骨組織工程。
英文摘要 Cells, scaffolds, and stimulation are three important components in cartilage tissue engineering. Osteochondrosis is a disorder of endochondral ossification in epiphyseal growth plate, leading to the osteoarthritis or the degenerative joint cartilage. Continuous passive motion (CPM), a natural physiological stimulation, should promote cell proliferation in joint defect regeneration. To better understand how continuous passive motion affects on the formation of repairing tissue in full-thickness cartilage defects, this study evaluated the effects of CPM in articular defects in rabbit model by macroscopic observation, computed tomography scanning, and histological evaluation. A 3-mm depth from the articular surface was produced in the patella groove and the medial condyle respectively to represent the high- and low- weight-bearing regions. Poly DL-lactic-co-glycolic acid (PLGA) that is a biodegradable polymer approved by FDA is widely used in biomaterial products. PLGA scaffolds were fabricated into the cylinder porous sponges by salt-leaching technique. The scaffolds were placed into the osteochondral defects for experimental group. Thirty-six rabbits were separated into six groups which were treated in individual study: with/without PLGA scaffold with immobilization on week 4 and 12; with/without PLGA scaffold with free cage activity for 4 and 12 weeks; and with/without PLGAscaffold with CPM on week 4 and 12. The results at four weeks showed the use of PLGA scaffold provided the mechanical functions at the medial condyle. Even though the histological scores of the immobilization treated with PLGA scaffold showed the highest, there was osteophyte which can limit the range of motion on the joint. After 12 weeks post-operation, the healing process of scaffold treated CPM were significantly better than that CPM alone at the medial condyle (p = 0.048). In conclusion, the articular cartilage function, and cell differentiation and proliferation are important to regenerate hyaline cartilage. This study showed that the scaffolds in combination of CPM can induce both chondrogenesis and osteogenesis in repaired area and would be a possible method for articular cartilage repair in clinic and cartilage tissue engineering.
