200407434 A7 _B7_ 五、發明說明(丨) 發明背景 組織工程學近年來快速興起,現已成為組織或器官移 植的另一潛在選擇。最近,與細胞模組化、細胞外基質構 建和模倣身體結構的合成性聚合物相關的新技術迅速進 展,許多研究者開始思考藉由宿主組織自我再生來治療身 體缺陷。傳統生物材料科學已思及使用如金屬,陶瓷及合 成性聚合物等非生物性材料來修復受損組織。為了要克服 使用此類非活體材料的限制,已嘗試經由結合細胞外基質 雜合性人工合成聚合物與模組化細胞來建構模倣天然組織 的人工器官,產生許多具有生物功能之人工組織(Langer R 等人,5W⑼ce 1993,14;260:920·6)。 組織工程達成修復及再生的方式,係基於在支援加強 且,在某些情況下,重建再生組織的聚合物鷹架的使用。 鷹架可能用於以受調控速率釋放生物活性物質,或直接地 影響被納入細胞或内生細胞的行為。這些不同的功能通常 要求多孔鷹架微細構造與多孔性特質。鷹架化學中常希望 涵括或模倣與細胞外基質成分、生長因子或細胞表面受體 之間發生的專一***互作用。現已使用一些天然及合成性 聚合物作為組織鷹架(Murphy WL等人,J Μα仏r 2000;50:50-8 ; Thomson RC 等人, Biomaterial 1999;20:2007-18 ; Peter SJ 等人, 1998;43:422-7 ; Murphy WL 專 k,J Periodontal Res 1999;34:413-9)。這些系統的微細構造範圍自水凝膠,開孔 系統一直到纖維基質。自組織工程系統的潛在應用範圍變 ___3_ 紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閱讀背面之注意事項再填寫本頁)200407434 A7 _B7_ V. Description of the Invention (丨) Background of the Invention Tissue engineering has risen rapidly in recent years and has become another potential choice for tissue or organ transplantation. Recently, new technologies related to the modularization of cells, the construction of extracellular matrix, and synthetic polymers that mimic the structure of the body have progressed rapidly, and many researchers have begun to think about treating body defects through self-regeneration of host tissues. Traditional biomaterial science has considered the use of non-biological materials such as metals, ceramics and synthetic polymers to repair damaged tissues. In order to overcome the limitation of using such non-living materials, attempts have been made to construct artificial organs that mimic natural tissues by combining extracellular matrix hybrid synthetic polymers with modular cells to produce many artificial tissues with biological functions (Langer R et al. 5Wcece 1993, 14; 260: 920 · 6). The way tissue engineering achieves restoration and regeneration is based on the use of polymer scaffolds that are enhanced in support and, in some cases, reconstructed regenerated tissue. The scaffold may be used to release bioactive substances at a regulated rate or directly affect the behavior of incorporated cells or endogenous cells. These different functions usually require the microstructure and porous properties of the porous scaffold. In scaffold chemistry, it is often desirable to include or mimic specific interactions with extracellular matrix components, growth factors, or cell surface receptors. Some natural and synthetic polymers have been used as tissue scaffolds (Murphy WL et al., J Μα 仏 r 2000; 50: 50-8; Thomson RC et al., Biomaterial 1999; 20: 2007-18; Peter SJ et al. 1998; 43: 422-7; Murphy WL Specialized, J Periodontal Res 1999; 34: 413-9). The microstructures of these systems range from hydrogels, open-cell systems to the fiber matrix. The potential application range of the self-organizing engineering system changes ___3_ Paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page)

After the invention description was broad, research has been conducted to find materials that have particularly promising organizational specificity, or may have broad applicability and can be used in several organizational systems. Polylactic acid (PLA), polyglycolic acid (PGA) and its copolymers such as poly (lactic-co-glycolic acid) (PLGA) have been used as three-dimensional (3D) polymer scaffolds for cell transplantation because they are Biodegradable and biocompatible (Athanasiou KA et al., 1996; 17: 93-102). Until now, the non-woven polyglycolic acid (PGA) fiber network reinforced by the physical bonding of PLA and PLGA between fibers has become the most commonly used in soft tissue cell transplantation due to its highly porous and cross-linked structure. The scaffold (Gao J et al., Α 1998; 42: 417-24). In the fields of pharmacy, medicine and biomedicine, biodegradable polymers have been used to develop biomaterials with a variety of applications (Benicewicz Β. C. et al., "7 Corpse 0 / less 7 knives 1999; 6: 64-94; Holland SJ et al, J 1986; 4: 155-180; Kyriacos AA # A 9 Biomaterial 1993; 17: 93_102; Gilding DK, "Biodegradable polymers" in biocompatibility of Clinical Implant Materials, 1981; CRC Press, Inc. :: pp. 209-232). Regarding methods for obtaining biodegradable polymers that allow surface modification, there have also been studies that indicate that polymer chains (eg, polyethylene glycol, PEG) are adhered to biodegradable polymer chains such as PLA or PLGA (Suh JK et al., Price 2000; 21: 2589_98). However, as a whole, there is still a need to improve the characteristics of these materials to optimize them and provide practical medical applications.

Description of the invention () Cell culture and improvement of tissue regeneration in vivo. When a biodegradable polymer scaffold is used for tissue culture, the interaction between the 'scaffold material and the cell may be affected by the properties of the polymer. For example, adsorbable peptides or proteins often interfere with cell adhesion (Myles JL et al., J Po-Ed 2000; 1 1: 69-86). In addition, the interaction between the scaffold and the cell can determine the function of the cell ... The interaction with the polymer surface has been shown to affect not only proliferation but also other processes such as cell differentiation and cell migration (Bures P et al./ (: ⑽ 的 / 如 / ⑽ “2001; 14: 72: 25-33; Park A et al., Ed 10 ′ · IkadaY, Valence 〇 Leak Order ζ · α / 1994; 15: 725-36) The first step in tissue growth and tissue function control is to inhibit any non-specific protein negative or peptides from being adsorbed to the polymerizable device used for cell culture. Once the polymer surface is loaded, it can be combined with the specific protein or state. To achieve functionalization (Ratner BD, Li Fang Qin Fang Qin 1995; 1 (): 797-8 () 4 ·). When inhibiting non-specific protein f, by combining specific adhesion factors ( (Such as fibrectin), the polymer surface will be able to promote specific cell adhesion and inhibit non-specific protein mediators of other types of cell adhesion. This is important in the case of bone defect treatment, eliminating unwanted cell types from Main challenges (MassiaSp et al. ^

The poly-1 polymer made of collagen has been used as a matrix to support cell growth. However, the collagen infiltrated by cells is porous Polymer pores are easy to destroy. In fact, these pores cannot sustain a period of time sufficient for some cells (such as fibroblasts) to establish a colony. In terms of its application as a bone fixation device, it has been greatly enhanced by the development of self-reinforcing polyglycolic acid with higher mechanical stability (Muzzarelli RA et al., May 5 1999; 87: 251_64). However, polyglycolic acid Non-woven webs are not suitable for use in organized_specific situations, as they are not easily modified. Deacetylated chitin (poly 1,4-D_glucosamine) is a partial deacetylation of chitin. After the derivative, chitin is the main structural polymer of arthropod exoskeleton. The degree of dehybridization of commercial preparations ranges from 50% to 90%. Chitosan is a crystalline polysaccharide and usually cannot be dissolved.

The description of the invention (lb) is as high as 90%. Example 5: Determination of mechanical properties of hybrid substrates Prior to determination of mechanical properties in the dry state, the substrates were stored at room temperature. In order to study the mechanical properties of the hybrid matrix, the matrix was individually cut into 4 cm XI cm pieces. The sample was placed at a speed of 5 mm / min on a film holder between two mounting plates (pulling instrument: LRX model, LLOYD instrument, USA). The Young's modulus, maximum load, and hardness were measured for heterogeneous matrices prepared by dissimilar methods and heterogeneous weight ratios of polyglycolic acid and deacetylated chitosan. These results show that the mechanical properties of the hybrid matrix increase as the polyglycolic acid increases from 30% to 70%. The maximum load value increased from nearly 3 N at 70% P / C to 13 N at 30% P / C. This result indicates that the use of polyglycolic acid during mixing improves mechanical hardness. Example 6: Measurement of water content of hybrid substrate The water content of a substrate is defined as the weight percentage of water in a water-saturated substrate. The water content of the substrate was measured as follows: Each substrate was soaked at room temperature and repeatedly weighed until a constant weight of the expanded substrate was obtained. The substrate was then dried to a strange weight under vacuum. Two important parameters to be determined to explain the water content of the matrix are porosity and the formation of hydrogen bonds between water molecules and the matrix. As shown in Fig. 4, the expansion rate of the water content of the substrate is in the range of about 200 to 500%. The expansion ratio of 70% P / C / G is 50% P / C, 30% P / C and 70%. __18__ 9 scale paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) ---- I --- II ---- · II (Please read the notes on the back before filling this page) · --- 200407434 A7 _____ B7 V. Description of the invention () P / C should be fast and high. Example 7: Degradation of a hybrid substance in vitro The polyglycolic acid / chitosan hybrid matrix was placed in a 15 ml bottle, each bottle containing 0.2 M phosphate buffer (PBS, pH 7.4 ). The body was stored on a shaker, and the shaker conditions were 50 rpm and 37. 〇2 Under different periods from 3 to 5 days. Seal the bottle to avoid volatilization of liquids during prolonged testing. In order to correctly define the degradation mode of the hybrid matrix, a rapid HPLC method was developed to simultaneously measure degradation of degradation end products (ie, glycolic acid). In this study, the degradation characteristics were determined by the simultaneous simultaneous determination of the glycoacetic acid monomer released in the incubation medium during the hydrolysis of the hybrid matrix. After a few days, a small amount (0.5 ml) of the buffer was removed and centrifuged (5,000 rpm); a portion of the resulting supernatant was injected directly onto the HPLC column. Glycolic acid released in the incubation buffer was using a JASCO instrument (model UV-970 / 975 'different wavelength detector and model ρ_98 pump, & ⑶, Tokyo Japan) and HPLC column (octadecane (C18), 4.6 x 250 mm, j. T. Baker 'USA). The mobile phase was 2% (仏) methanol 'in phosphate buffer, which contained 0.002M moth tetrabutyl beryllium. Chromatographic analysis was performed at a flow rate of 0.6 ml / min, and the absorbance of the eluate was detected at 210 nm. The L-Bei & L Peak's Recognition System uses certified standards using chromatographic analysis. The quantitative value of glyoxylic acid was obtained by integrating the peak region using an externally standardized method. Degradation is defined as the weight percent of glycolic acid in the solution. ^ This paper size applies to China National Standard (CNS) A4 (210 X 297 public directors) " ---- 1 II I --- · I 1 (Please read the precautions on the back before filling this page) Order: i-line · 200407434 A7 ---------- B7 " ---------- V.

After 35 days of exposure, 70% of the P / C stilbene hybrids lost nearly 80% of the acetic acid. The & acetic acid released by the thermal phase separation method or the solvent-molded particle escape method has a similar curve and degradation rate. The general appearance of all hybrid matrices changes over time during degradation. . : Measurement of contact angle of hybrid matrix 基质 Polyglycolic acid / chitosan hybrid matrix and tissue culture polystyrene (TCPS) using imaging contact angle system (model SZ-ST, Olympus, Japan) Measure the water contact angle. The water contact angle is measured on a dry substrate. _Line. The water contact angle of the P / C and that of the P / C / G substrate varies from approximately 20 ° at 50% P / C to 70 at 30% P / C / G. . Water contact angle is a measure of hydrophilicity. Larger hydrophilic substrates have smaller water contact angles. The contact angle of the hybrid matrix constructed by the thermal phase separation method or the solvent-molded particle filtration method is lower than TCPS (83.), that is, it has greater hydrophilicity. Example 9: Cell Adhesion Study of Hybrid Matrix For the assessment of the kinetics of cell adhesion, 5x105 cells / cm² density fibroblast cells were implanted on TCPS and polyacetic acid / deacetylamidine chitin hybrid matrices. The hybrid matrix was gently washed with Hank's physiological buffer solution (HBSS, Life Technologies), and the number of adherent cells was quantified by staining the cells with cone blue.

Column i 10: Cytocompatibility test Put a sterilized membrane 2x2 cm into a 6-well culture plate (IWAKI, Japan) 'and use TCPS as a control group. Fibroblast cells were implanted in the matrix and control wells at a density of χ × 05 cells / cm 2. Cell morphology and adhesion were measured on a ττ image analysis system connected to an inverted phase contrast microscope (1X70, Olympus, Japan). A CCD image camera (color camera model VK-C370, Hitachi, Japanese) was used to capture and obtain images (Optimas 5.2, Optimas, USA). The substrate affected the cell morphology after 24 hours of incubation. Cell morphology photomicrographs show cells in the form of extended spindles distributed on P / C and P / C / G hybrid matrices. As shown in Figure 6, the number of fibroblasts adhered to all polymer films after 24 hours of culture was similar to that of TCPS control subjects. Among all hybrid matrices, 70% P / C matrix exhibited the greatest degree of fibroblast cell adhesion after 48 hours in culture. Surprisingly, the 70% P / C matrix is not only more hydrophilic, but also more cells adhere to it. Example 11: Use ntazole i_ (Mrn test to test cytotoxicity.

Explanation of the invention (> y) Death (Figure 10). In order to prove which types of cells are induced by heterozygous matrix a, the inventors studied the changes in cell appearance by double staining with annexin V and PI. Non-apoptotic viable cells (annexin V positive, pi negative), early apoptotic cells (annexinV positive, PI negative) and late apoptotic cells can be detected by cells stained with fluorescent annexinV and ρ conjugate (annexin V positive). Figure η shows fragmentation of nucleus and chromatin concentration after treatment with hybrid matrix a. These are characteristics of apoptosis. After 4 days of incubation with hybrid matrix A at a concentration of 500, most of the cells were stained red, indicating that endometriotic cells belonged to advanced apoptosis. In order to determine whether apoptosis was induced by treatment with P / C hybrid matrix A, the inventors studied the fragmentation pattern of endometriotic cells, and exposed to hybrid matrix A for 4 days (Figure 12). DNA-ladder was observed after 72 hours of culture. Quantitative analysis by agarose gel electrophoresis on the 4th day revealed that the cells' path to apoptosis after treatment with P / C hybrid matrix A concentration of 500 // g / ml (Fig. 12). In order to prove the frequency of apoptosis in the cell phase after treatment with p / c hybrid matrix A, the inventors performed flow cytometry analysis with AnnexinV staining (Figure 13), and speculated that p / c hybrid matrix A can induce Adhered cells produce apoptosis. The inventors have shown in the past that nearly 80% of cells will undergo apoptosis after treatment with p / c hybrid matrix a for 4 days.
