Description

血小板外泌体富集管 技术领域
本发明是有关于一种血液取样装置,特别是一种血小板外泌体富集管。
背景技术
人体血液主要包括血浆和血细胞两部分,血细胞主要成分为红血球、白血球和血小板。全血可以制备成各种成分,在理想条件下保存,可以有效用于各种治疗。其中血小板在临床治疗发现具有体外止凝血和快速启动内源性生长因子的作用,对人体具有良好的促细胞生长和修复作用。
随着现代医学的发展,微量血液成分如富含血小板血浆(platelet rich plasma,PRP)广泛用于临床外科和医学美容,其为从受试者自体抽取血液,收集富含血小板的血浆,及时通过医疗手段重新注入患者皮肤或组织表面,达到自身机体的治疗和恢复医疗作用。可避免利用外体血制品发生的排斥反应。
PRP是利用血小板表面的外泌体分泌生长因子及抗发炎因子来治疗身体的不适,主要用于骨关节炎、肌肉韧带损伤、抗发炎及组织修复。此外,PRP亦可应用于医学美容和牙科,例如在医学美容的应用可减少皱纹,在牙科方面的应用可以填充牙髓,促进植牙金属与牙髓腔密合增加生长,进而增加植牙成功率。
然而血小板除了表面的外泌体能分泌生长因子及抗发炎因子外,另外在血小板的细胞质中另外还有3个异构体(isoforms)的外泌体。习知的PRP只活化了血小板表面的外泌体,因而只有血小板表面的生长因子被活化释放,血小板细胞膜内部另外3个异构体的外泌体没有被利用到。因此发展一种可以打破血小板细胞膜的临床医疗器械,进而利用血小板细胞膜内部3个异构体的外泌体活化释放的生长因子和抗发炎因子,以提高临床应用的疗效和范围至关重要。

毛玻璃珠130设置于容置空间113内,其中每个毛玻璃珠130的表面131具有均匀分布的凹凸形状。表面131所具有均匀分布的凹凸形状可经由化学处理方法或物理处理方法所形成。化学处理方法例如施行毛玻璃化处理的方法,可通过将玻璃珠浸渍于氟化氢与氟化铵的混合溶液中,将浸渍面作化学性表面处理而得到毛玻璃珠130。物理处理方法包含利用加压空气将晶质二氧化硅粉末及碳化硅粉末等喷吹于玻璃珠的表面的喷砂处理,以得到毛玻璃珠130;或以经水沾湿的附着有晶质二氧化硅粉末及碳化硅粉末等的刷子磨刷玻璃珠以得到毛玻璃珠130。而每个毛玻璃珠130的表面的表面粗度(RMS)可为0.01μm至0.5μm,每个毛玻璃珠130的平均粒径可为2mm至10mm。更佳地,于管体110的容置空间113中可设置20颗至50颗毛玻璃珠130,但不以此为限。并请参照下表一至表三,其中表一所示为与毛玻璃珠130尺寸相关的性质,表二所示为毛玻璃珠130的化学性质,表三所示为毛玻璃珠130的物理性质。
表一、与毛玻璃珠130尺寸相关的性质

表二、毛玻璃珠130的化学性质
表三、毛玻璃珠130的物理性质

血小板外泌体富集管100可通过其中所包含表面具有均匀分布的凹凸形状的毛玻璃珠,在制备血小板外泌体富集液时,利用物理原理打破血小板的细胞膜,使在血小板的细胞质中另外3个异构体的外泌体亦可被活化释放,进而得到包含多个抗发炎因子和生长因子的血小板外泌体富集液,且所得到的血小板外泌体富集液中各类生长因子的浓度相较于习知的富含血小板血浆增加数倍,使得后续应用于临床的治疗效果更好。

试验例
血小板能分泌多种生长因子、抗发炎因子,具有促进细胞移动、分化、分裂、基质增生、血管新生和平衡等功能,其中包含的重要生长因子如血小板衍生生长因子(Platelet-derived growth factor,PDGF)、转化生长因子α(Transforming growth factorα,TGFα)、转化生长因子β(Transforming growth factorβ,TGFβ)、类胰岛素生长因子(Insulin-like growth factor 1,IGF-1)、血管内皮生长因子(Vascular endothelial growth factor,VEGF)和介白素1-受体拮抗剂(Interleukin 1receptor antagonist IL1-Ra),PDGF能吸引干细胞、促进干细胞分裂细胞外基质分泌、刺激成骨作用等功能。TGFα能促进细胞外基质分泌、促进母细胞成熟。TGFβ能帮助改善过敏体质,调节免疫系统正常发展,TGFβ超家族中包含TGFβ1、TGFβ2和TGFβ3。IGF-1能促进骨折愈合,皮肤、肌肉、血管肌腱及韧带生长。VEGF可以促进血管新生、抑制破骨细胞。IL1-Ra可以抑制发炎因子-介白素1,是重要抗发炎因子。
为测试本发明的血小板外泌体富集管可制备包含多个抗发炎因子和生长因子的血小板外泌体富集液,本试验例进一步将抽取自受试者的血液样本以采血针注入本发明的血小板外泌体富集管,放置于37℃的恒温箱静置以稳定血小板活性,1-4小时后自恒温箱取出并置入飞轮式离心机内套筒中,以4000rpm/min的条件离心5分钟,此时血液样本已分离为血小板外泌体富集液层和血球层。将离心结束后的血小板外泌体富集管取出,再以长针 自盖体的注入口插入管体中,抽取上层的血小板外泌体富集液,即得到制备完成的血小板外泌体富集液,后续可用于注射入受试者所需使用的部位。所使用的血小板外泌体富集管可为图1、图2、图3或图5所示的血小板外泌体富集管。
试验上进一步将以本发明的血小板外泌体富集管所制备的血小板外泌体富集液(以下简称「PRPII」),与习知方法所制备的富含血小板血浆(以下简称「PRP」)中各类生长因子和细胞因子的浓度进行比较,请参照表四和表五,表四为PRPII于临床应用于各组织修复所需的生长因子的浓度增加倍数,其数值系以PRP为基准。表五为PRPII和PRP于各细胞因子的浓度,其中PRPII后括号的数字表示静置于恒温箱的时间(小时),而各细胞因子的浓度单位皆为pg/mL。
表四、PRPII于临床应用于各组织修复所需的生长因子的浓度增加倍数
表五、PRPII和PRP于各细胞因子的浓度
表四的结果显示,由本发明的血小板外泌体富集管所制备的PRPII其中所包含各组织修复所需的生长因子的浓度相较于习知的PRP皆有显着地增加。且由表五的结果显示,生长因子浓度与血液样本于37℃的静置时间有关,最佳的静置时间为3-4小时,可以获得最好的结果,其中PRPII所含有的抗发炎因子IL1-Ra浓度为PRP的4.15倍,PRPII所含有的PDGF生长因子浓度是PRP的5.4倍。而PRPII所包含的肿瘤坏死因子α(Tumor necrosis factorα,TNFα)浓度与PRP相比虽稍多,但也不致于因培养时间较长而有大幅增加的情况,显示本发明的血小板外泌体富集管确实可制备含有高浓度各类生长因子的PRPII。
试验上将由本发明的血小板外泌体富集管所制备的PRPII用于临床试验,进一步验证PRPII对于退化性关节炎病人注射后疼痛指数下降的效果。试验上的受试者为30位退化性关节炎第III期的患者(VAS疼痛等级:8-10),上述受试者每2周接受1次PRPII治疗,总共接受治疗次数为5次,试验上另包含接受PRP治疗的受试者以做为对照,PRP治疗的策略和PRPII治疗相同。请参照表六和表七,表六为受试者的疼痛改善百分比,表七为疗程结束后试者的疼痛等级结果。
表六、受试者的疼痛改善百分比
表七、疗程结束后试者的疼痛等级结果
由表六和表七的结果显示,全部接受PRPII治疗的受试者在疗程结束后疼痛皆获得改善,其中更有80%的受试者的疼痛等级由原本的8-10降至2-4,可证明由本发明的血小板外泌体富集管所制备的PRPII具有显著改善退化性关节炎患者疼痛的效果。
而由本发明的血小板外泌体富集管所制备的PRPII除了退化性关节炎、肌腱损伤的注射治疗的临床运用外,亦可运用于多种临床治疗,例如植牙治疗、医美治疗、秃发治疗、骨科治疗、外伤治疗、眼科治疗和妇产科治疗等。用于植牙治疗时,通过混合玻尿酸变成半固体填塞物填补于植牙处,可以促进植牙体与骨质紧密合,增加植牙成功机率。用于医美治疗时,可注射于皮下促进胶原蛋白再生使肤质改善,也可与脸部注射玻尿酸同时使用,使效果加乘。用于秃发治疗时,注射于头皮可使毛发再生。用于骨科治疗时,术后直接注射骨折缺陷处促进骨愈合,或注射于骨空洞促进生长。用于外伤治疗时,可与人工皮结合覆盖于糖尿病足及其他不易愈合的慢性溃烂伤口,譬如褥疮或烧烫伤,使其加速愈合。用于眼科治疗时,可制成眼药水,治疗干眼症及慢性角膜溃疡或角膜营养不良。用于妇产科治疗时,可由子宫颈注射PRPII入子宫,使子宫内膜肥厚,以改善因为子宫内膜不够肥厚导致的不孕症,帮助怀孕成功比率。
综上所述,本发明的血小板外泌体富集管因包含表面具有均匀分布的凹凸形状的毛玻璃珠,在制备血小板外泌体富集液时,可利用物理原理打破血小板的细胞膜,使在血小板除了表面的外泌体以外,细胞质中另外3个异构体的外泌体亦可被活化释放,进而得到包含多个抗发炎因子和生长因子的血小板外泌体富集液,且所得到的血小板外泌体富集液中各类生长因子的浓度相较于习知的富含血小板血浆增加数倍,使得后续应用于临床的治疗效果更好,并可应用于多种临床治疗,具有极大的临床应用前景。
虽然本发明已以实施方式揭露如上,然其并非用以限定本发明,任何熟习此技艺者,在不脱离本发明的精神和范围内,当可作各种之更动与润饰,因此本发明的保护范围当视后附的权利要求所界定者为准。
