Abstract
本发明涉及包含永生化干细胞的富含外泌体的培养液及肉毒杆菌毒素的功能性组合物。具体地,根据本发明的功能性组合物在抑制胶原蛋白及弹性蛋白的分解的同时还能促进其合成,且能改善皱纹,促进细胞再生,从而可用于皮肤再生、改善皱纹、改善皮肤弹性、抑制皮肤老化及抑制皱纹产生的功能性材料或创伤治疗用途。
Description
技术领域
本发明涉及包含永生化干细胞的富含外泌体的培养液(exosome-richconditioned medium)及肉毒杆菌毒素的功能性组合物。
背景技术
皮肤作为对人体进行保护或防御的主要器官的同时,还是全面覆盖身体表面的最宽的器官,其由表皮、真皮及皮下组织构成。其中,位于表皮最外层的角质层由角质和脂质构成,其能抑制有害物质的渗透或水分蒸发,保护人体免受细菌感染或外界刺激。角质层以两周为周期脱落而形成新的角质层。
皮肤经常受到压力或紫外线等刺激的损伤,由于这些诱发皮肤损伤的因素导致角质层和脂质层受到破坏,经皮水分流失迅速增加。不仅如此,还可能会发生由于皮肤干燥、皱纹生成、瘙痒症和细菌感染引起的炎症。人角质形成细胞可以因外界刺激而产生和释放由IL-1α开始的IL-6、IL-8、TNF-α等多种细胞因子,这些细胞因子诱导皮肤刺激或介导局部炎症反应。
尤其,如果紫外线等外部刺激反复对角质层造成损伤,或者正常角质层的恢复延迟,皮肤老化可能会加速,且可能会发展成皮肤疾病。因外界损伤引起的角质层的快速修复可以缓解皮肤干燥、皮肤老化和瘙痒等,并且,这些可以通过促进用于诱导人角质形成细胞正常分化和增殖的皮肤再生来预防。皮肤再生的愈合期根据组织损伤的大小或程度而不同。愈合是止血、炎症、增殖和重塑四个发展过程依次通过调控而发生的过程,其需要各种细胞相互作用、生长因子和细胞因子。
在这方面,韩国授权专利第10-2214378号涉及一种用于皮肤再生、改善皱纹、抗炎或皮肤美白用组合物,其公开了如下内容:即沙苑子苷A(complanatoside A)增加皮肤成纤维细胞中的胶原蛋白总量,抑制胶原酶活性,提高皮肤再生或皱纹改善效果,抑制一氧化氮产生以显示抗炎效果,减少黑色素总量以显示美白作用,从而可用作药物组合物、皮肤外用剂、化妆料组合物或保健功能食品。
发明内容
发明要解决的问题
本发明的目的在于,提供包含永生化干细胞的富含外泌体的培养液及肉毒杆菌毒素的功能性组合物。
本发明的另一目的在于,提供永生化干细胞的富含外泌体的培养液及肉毒杆菌毒素的用途。
用于解决问题的手段
为了实现所述目的,本发明提供一种功能性组合物,其包含永生化干细胞的富含外泌体的培养液(exosome-rich conditioned medium,ERCM)及肉毒杆菌毒素。

实验例3.对胶原蛋白降解酶抑制的确认
通过基质金属蛋白酶-1(matrix metalloproteinase-1,MMP-1)蛋白的活性抑制来确认了获得的富含外泌体的培养液的胶原蛋白降解酶抑制效果。
具体地,将100μl/ml的富含外泌体的培养液及5个单位(units)的A型肉毒杆菌毒素(美迪妥适(medytox)株式会社,韩国)添加到包含底物(MCA-Lys-Pro-Leu-Gly-Leu-DPA-Ala-Arg-NH2)和重组人MMP-1蛋白(Cat.#M9195,Sigma-Aldrich)的反应液。将其在320nm的激发波长(excitation)和405nm的发射波长下测定吸光度,测定时间为5分钟。此时,作为对照组,使用未进行任何处理的正常对照组,仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素及正常培养液处理组。对于其结果,将MMP-1蛋白的活性基于正常对照组的活性来计算成百分比,并示于图3。
如图3所示,在仅用肉毒杆菌毒素处理的情况下,未能抑制MMP-1蛋白的活性,然而,与分别用富含外泌体的培养液和肉毒杆菌毒素处理的情况相比,当用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,MMP-1蛋白的活性显著减少。尤其,这种效果也显著高于一起使用肉毒杆菌毒素和正常培养液进行处理的情况。
实验例4.对弹性蛋白分解酶的抑制的确认
通过MMP-12(matrix metalloproteinase-12)蛋白的活性抑制来确认了获得的富含外泌体的培养液的弹性蛋白分解酶抑制效果。
具体地,将100μl/ml的富含外泌体的培养液及5个单位的A型肉毒杆菌毒素添加到包含底物(N-succinyl-Ala-Ala-Ala-p-nitroanilide)及人嗜中性粒细胞弹性蛋白酶(elastase,Cat.#MAK246,Sigma-Aldrich)的反应液。使用酶联免疫检测仪(ELISA reader)在410nm条件下测定吸光度。此时,作为对照组,使用未进行任何处理的正常对照组,仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素及正常培养液处理组。对于其结果,将MMP-12蛋白的活性基于正常对照组的活性来计算成百分比,并示于图4。
如图4所示,在仅用肉毒杆菌毒素处理的情况下,未能抑制MMP-12蛋白的活性,然而与分别用富含外泌体的培养液和肉毒杆菌毒素处理的情况相比,当用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,MMP-12蛋白的活性显著减少。尤其,这种效果也显著高于一起使用肉毒杆菌毒素和正常培养液进行处理的情况。
实验例5.对胶原蛋白合成促进的确认
以如下方式,确认了所获得的富含外泌体的培养液的胶原蛋白合成促进效果。
首先,使用培养基106(medium 106)以常规方法培养了作为人真皮成纤维细胞株的CCD986SK(Thermo Fisher Scientific)细胞株。将制备的细胞接种到6孔板,每孔5×104,并向其添加100μl/ml的富含外泌体的培养液及5个单位的A型肉毒杆菌毒素。培养72小时后,用马松三色(Masson's Trichrome)对培养的细胞的胶原蛋白纤维进行染色,并用显微镜进行观察。并且,取细胞培养液,使用羊抗1型胶原蛋白-UNLB抗体(Southern Biotech)进行ELISA,并在450nm下测定吸光度,从而确认1型胶原蛋白的含量。此时,作为对照组,使用未进行任何处理的正常对照组,仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素及正常培养液处理组。至于其结果,即将显微镜观察结果以及ELISA分析的结果示于图5。
如图5所示,在仅用肉毒杆菌毒素处理的情况下,未能促进胶原蛋白的合成,然而,在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,胶原蛋白的合成显著增加。尤其,这种效果也显著高于使用肉毒杆菌毒素和正常培养液一起进行处理的情况。
实验例6.对弹性蛋白合成促进的确认
以如下方式,确认了所获得的富含外泌体的培养液的弹性蛋白合成促进效果。
具体地,以与实验例3相同的条件及方法培养用富含外泌体的培养液及A型肉毒杆菌毒素处理的细胞,培养时间为7天。对培养的细胞的弹性蛋白纤维以如下方式进行确认:即用兔抗-人α-弹性蛋白抗体(Bio-Rad)进行染色,并用常规的方法进行免疫染色,之后用显微镜进行观察。并且,取细胞培养液,使用相同抗体进行ELISA,并在450nm下测定吸光度,从而确认了弹性蛋白的含量。此时,作为对照组,使用未进行任何处理的正常对照组,仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素及正常培养液处理组。至于其结果,即将显微镜观察结果及ELISA分析的结果示于图6。
如图6所示,在仅用肉毒杆菌毒素处理的情况下,不仅未能促进弹性蛋白的合成,相反还表现出了抑制弹性蛋白的倾向,然而,在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,弹性蛋白的合成显著增加。尤其,这种效果也显著高于使用肉毒杆菌毒素和正常培养液一起进行处理的情况。
实验例7.对皮肤皱纹改善的确认
以如下方式,确认了所获得的富含外泌体的培养液的皮肤皱纹改善效果。
首先,用UVB灯(沃德公司)向7周龄雄性无毛(hairless)小鼠(SKH-1)的背部皮肤照射紫外线(UVB)。具体地,第一周是以1最小红斑量(minimun erythema dose,MED)照射UVB,第二周以2MED进行照射,第三周以3MED进行照射,第四周至第十周以4MED进行照射,从而诱发皮肤皱纹。混合50μl的富含外泌体的培养液和5个单位的A型肉毒杆菌毒素并皮下注射到诱发皮肤皱纹的小鼠。此时,注射是以1cm为间隔共分在构成圆形的5个位置进行注射,注射后第一天、第二周及第四周观察了皱纹。此时,作为对照组,使用未进行任何处理的正常皮肤组、仅用UVB处理的UVB处理组、仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素和正常培养液处理组。之后,使用有机硅聚合物(Impression Material)复制皱纹,并以将光的入射角固定在20度的状态用相机拍摄了皱纹的明暗图像。使用图像分析程序(Skin Visiometer SV600software)从拍摄的照片分析了粗糙度(roughness)。至于其结果,将所拍摄的图片示于图7,通过分析皮肤的粗糙程度来确认的皱纹评分(score)结果示于图8。
如图7及图8所示,UVB照射形成的皱纹在观察四周后仍维持11.7分。另外,在仅用肉毒杆菌毒素处理的情况下,处理一天后虽然改善至5.6分,然而第二周、第四周分别为7.5分、10.3分,即再次形成皱纹。然而,在用肉毒杆菌毒素和富含外泌体的培养液或正常培养液一起处理的情况下,皱纹的再形成明显受阻,尤其在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,四周后评分为6.4分,完全阻断了皱纹的再形成,维持了皱纹改善效果。
因此,由上述内容可知,与单独用肉毒杆菌毒素处理、或用肉毒杆菌毒素处理和正常培养液一起处理的情况相比,在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,皱纹生成抑制效果显著增加,并且可以长时间维持这种效果。
实验例8.皮肤再生效果的确认
通过划痕试验(wound scratch assay)方法确认了获得的富含外泌体的培养液的皮肤再生效果。
首先,使用EpiLife(Gibco)培养基以常规方法培养了作为人表皮角质细胞株的NHEK细胞株(Guangdong BioCell Biotechnology Co.,Ltd.)。将制备的细胞接种至6孔板,每孔3×105,并用100μl的移液管尖端诱导刮痕(scratch)创伤。之后,向其添加100μl/ml的富含外泌体的培养液和5个单位的A型肉毒杆菌毒素,培养24小时并进行观察。此时,作为对照组,使用未进行任何处理的正常对照组,仅用肉毒杆菌毒素处理的肉毒杆菌毒素处理组、以及用肉毒杆菌毒素和正常培养液处理的肉毒杆菌毒素及正常培养液处理组。使用相差显微镜(phase-contrast microscope)进行拍摄,从而定量评价了细胞的再生程度。
如图9所示,确认了正常对照组细胞再生约20%、肉毒杆菌毒素处理组细胞再生约35%。相反,在用肉毒杆菌毒素和富含外泌体的培养液或正常培养液一起处理的情况下,细胞再生显著增加,尤其,在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,约85至90%的细胞再生。
因此,由上述内容可知,在用富含外泌体的培养液和肉毒杆菌毒素一起处理的情况下,细胞再生效果显著增加。
