Description
发明领域
本发明属于干细胞和再生医学领域。特别地,本发明提供了源自人类口腔粘膜干细胞的分泌蛋白质组(secretome)的组合物。还提供了用于获得、操纵干细胞分泌蛋白质组的方法以及在疗法中使用干细胞分泌蛋白质组的方法。
发明背景
人口腔粘膜源性干细胞(hOMSC)是源自口腔粘膜的固有层的独特干细胞群(Marynka-Kalmani等2010)。hOMSC表达由胚胎干细胞、神经嵴干细胞和间充质干细胞的标志物组成的独特免疫表型。全基因分析鉴定出,hOMSC从体内向体外的转移引起在哺乳动物生物体的胚胎和胎儿发育阶段期间参与神经嵴细胞谱系的发育的基因的差异表达。
神经嵴是一种短暂的发育结构,产生外胚层和间充质起源的多种细胞谱系,分别包括神经元谱系和胶质细胞谱系以及成软骨细胞谱系、成骨细胞谱系、脂肪细胞谱系和成纤维细胞谱系。还已经显示出hOMSC在体外和体内分化成这些细胞谱系(Marynka-Kalmani等2010、Treves-Manushevitz等2013、Ganz等2014a、2014b)。
发现分化为多巴胺能样神经元细胞或星形胶质细胞样细胞并且移植在体内的hOMSC在动物模型中具有治疗作用(Ganz等2014a、2014b)。此外,显示出具有一定治疗活性的幼稚hOMSC(hOMSC)甚至在这些动物模型中无效,它们的治疗作用与安慰剂的治疗作用相似。
最近,已经显示出胚胎干细胞和成体干细胞也是细胞外囊泡的一个延伸来源(Desrochers等2016、Konala等2016)。细胞外囊泡(EV)是由真核细胞的细胞质释放的大小范围从50nm至1.5微米-2微米的囊泡。
EV按照其生物发生和大小主要分为2个主要类别:具有50nm-1500nm的大小范围的微囊泡或脱落微囊泡;和具有30nm-120nm的大小范围的外泌体(exosome)。外泌体是源自多泡体的腔膜的脂双层膜囊泡,其通过与细胞膜融合组成性释放。微囊泡和外泌体的生物发生是不同的。微囊泡通过出芽和从膜分裂在质膜处形成。外泌体源自内体和高尔基体系统并且至少部分通过转运所需要的内体分选复合物植根于细胞表面,在细胞表面它们经历胞吐作用。
细胞外囊泡包含含有蛋白、脂质、核酸的货物(cargo)(Desrochers等2016、Xu等2016)。取决于细胞的起源、它的生理和病理状态以及细胞释放部位,EV内容物是异质的并且处于动态状态中。由于货物被选择性地分选到外泌体中,外泌体的组成可以与它们起源的细胞不同。除了经典的细胞-细胞接触方式和用于旁分泌和自分泌作用的可溶性因子的分泌之外,已经显示出EV的货物用作用于细胞-细胞通讯的一种方法。关于EV生物作用的大多数知识源自对癌细胞完成的工作。体外和体内已经显示出,EV的货物诱导癌细胞增殖和存活和血管生成以及肿瘤成纤维细胞迁移、存活和生长(Antonyak等2015)。外泌体已经被证明是遗传物质的载体并且被推荐为用于癌症诊断和预后的生物标志物并且被提出用于监测治疗效力。目前,基于外泌体递送肿瘤疫苗和药物被评价为用于癌症的治疗策略(Gue等,2017)。
发现来自源自骨髓和脂肪组织的成体干细胞的条件培养基在心脏缺血中和伤口愈合中具有治疗潜力(Lai等2010、Hu等2016)。
存在越来越多的证据证明,微囊泡和外泌体之间的货物的内容物有差异并且该差异受细胞的起源控制(Kanada等2015)。此外,最近的数据指示,货物的性质对由多种类型的癌细胞释放的EV和对由不同类型的干细胞释放的那些EV二者是细胞特异性的(Villarroya-Beltri等2014、Lopez-Verrilli MA等2016)。
WO 2008/132722公开了胃肠道的粘膜并且特别是口腔粘膜的固有层作为多能成体干细胞(pluripotent adult stem cell)的来源。
WO 2013076726公开了源自口腔粘膜的固有层的干细胞(OMSC)作为用于选择性分化成不同神经谱系的来源,以及它们在诱导或保存神经发生中的以及用于神经退行性和精神紊乱的疗法的以及在由于创伤引起的神经组织损失中的用途。
US2016/0256496涉及牙龈成纤维细胞源性产物例如条件培养基,及其在用于预防或治疗骨科病理诸如骨关节炎和类风湿性关节炎的方法中的用途。
Med Cell Ltd.的WO/2017/001649、WO/2016/082882和WO/2016/083500公开了产生由间充质干细胞或树突状细胞分泌的分泌蛋白质组的特定方法。
WO/2014/057097公开了一种用于通过在适当的培养基中共培养成体人类间充质干细胞和成体完全分化心肌细胞以获得预处理的(preconditioned)成体人类间充质干细胞来调节成体人类间充质干细胞的分泌蛋白质组的方法。
仍然存在对可用于预防和治疗疾病和紊乱以及促进组织再生的组合物的未满足的需求。这样的组合物可以有益地源自独特、可扩增和容易可及的来源。
发明概述
源自口腔粘膜的固有层的人类干细胞(hOMSC)的条件培养基或分泌蛋白质组现在被公开作为治疗性组合物。本发明部分基于以下发现:幼稚hOMSC分泌蛋白质组的组合物是独特的并且因此具有独特的治疗潜力,其优于源自其他来源的幼稚干细胞的分泌蛋白质组。此外,hOMSC刺激可能引起反映为分泌蛋白质组内容物的变化并且因此反映为它的治疗能力的细胞应答。还设想了从所述hOMSC刺激得到的分泌蛋白质组对hOMSC刺激的细胞是独特的,并且如果应用到由其他来源衍生的成体干细胞,相同的刺激将导致不同的分泌蛋白质组。
本文首次公开了幼稚hOMSC的分泌蛋白质组具有在存在、不存在或相对量的细胞因子、趋化因子和核酸方面与其他干细胞的分泌蛋白质组不同的独特特征。
本文还公开了hOMSC和包含源自其的分泌蛋白质组的无细胞组合物能够促进糖尿病伤口愈合,表明hOMSC分泌蛋白质组在促进新血管系统、细胞增殖和结缔组织形成中的潜在用途。出乎意料地,hOMSC及其在伤口愈合中的分泌蛋白质组活性优于源自其他来源的干细胞和分泌蛋白质组。
根据本发明的源自可及的、可再生的和可消耗的幼稚hOMSC细胞来源的分泌蛋白质组易于获得和使用,而不需要诱导细胞的分化。
根据一个方面,本发明提供了一种无细胞组合物,所述无细胞组合物包含由人类口腔粘膜干细胞分泌的物质(hOMSC源性分泌蛋白质组)连同至少一种载体、赋形剂或稀释剂。
包含根据本发明的hOMSC源性分泌蛋白质组的无细胞组合物在它们的内容物方面是独特的并且与其他来源的干细胞的分泌蛋白质组不同。
根据一些实施方案,hOMSC是幼稚的。
根据一些实施方案,无细胞组合物包含:

发明详述
本发明提供了用于治疗和预防疾病和紊乱的来自人类口腔粘膜的成体干细胞的分泌蛋白质组。
hOMSC是神经嵴(NC)源性干细胞类型,其在发育中的集落中共表达多能性标志物Oct4、Nanog和Sox2以及NC-SC标志物,Snail、Slug、Sox10、Twist和Notch 1(Marynka-Kalmani等2010;Widera等2009)。NC是脊椎动物胚胎的短暂的神经外胚层结构。在其胚胎存在期间,它产生迁移性专干细胞(multipotent stem cell),其填充(populate)多种原基组织(primordial tissue),在原基组织中迁移性专干细胞分化成神经谱系和/或具有被称为外胚层间质(ectomesenchyme)或中外胚层的间充质表型的谱系。这些NC-SC中的一些在成体中保持相对未分化的状态,甚至在间充质起源的组织诸如真皮和骨髓中具有神经分化的倾向。
经典的全部成体群体(whole adult population)包含少量的干细胞,并且因此干细胞的扩增和分离是费力的、漫长的并且通常不是有效的。已经证明,由源自口腔粘膜的固有层的原代全部群体和扩增的全部细胞群体主要(多于80%)由幼稚干细胞组成。显示出从三个不同供体的口腔粘膜获得的高比例(80%-90%)的细胞群体表达间充质干细胞标志物。Marynka-Kalmani等2010年(同上)的研究已经证明,从以可忽略不计的发病率获得的3-4×2×1mm的活组织检查高成本效益地并且可重复地产生了数万亿hOMSC。
从用于临床利用的实体组织分离干细胞的经典方法包括通过酶消化或通过外植由细胞外基质释放细胞;扩增原代全部群体以获得足够大的群体;和从全部群体分离干细胞。
来自口腔粘膜固有层的分离的干细胞群体的质量和数量很大程度上不受衰老的影响,并且可以在体外扩增而不损失其多能性,并且因此是用于将分泌蛋白质组再施用到有相应需要的受试者以有效实现组织再生和其他治疗过程的安全且可靠的来源。
定义
口腔粘膜是口腔的粘膜内衬(lining),即:颊部和牙槽嵴,包括牙龈和腭、舌、口底、和唇的口腔部分。口腔粘膜由外胚层起源的上皮组织和固有层(LP)组成,固有层是外胚层间质起源的结缔组织。与口腔中外胚层间质起源的结缔组织相似,口腔粘膜固有层(OMLP)的细胞源自胚胎外胚层神经嵴。人类口腔粘膜中的伤口主要通过再生愈合。愈合的速率比皮肤或其他结缔组织中快,并且看起来受年龄和性别的影响可忽略不计(Szpaderska,A.M.等,J Dent Res,2003,82,621-626)。
“干细胞”(SC)是未分化的细胞,其可以产生一系列成熟的功能细胞。
“胚胎干(ES)细胞”是源自胚胎胚泡的内细胞团的细胞,是多能的,因此具有发育成任何器官或组织类型或者至少潜在发育成完整的胚胎的能力。
“成体干细胞”是生物体出生后源自生物体的组织、器官或血液的出生后干细胞。
“多能干细胞”是能够产生三个胚胎细胞层及其衍生物细胞谱系和组织的干细胞;
“专能干细胞”是能够形成构成整个组织或器官的多个(multiple)细胞谱系的干细胞;
根据本发明的分泌蛋白质组是包含其多种形式的由人类口腔粘膜源性干细胞分泌或释放到培养基中的可溶性物质和不溶性物质的组合物。这些物质尤其包括:
2.可溶性分子如:
a.蛋白
b.肽
c.激素
d.多种DNA和RNA种类
e.核酸的寡聚物(oligomer)
f.具有高于1,000道尔顿的分子量的其他分子
3.包含以下的细胞外囊泡:
a.蛋白:生长因子、细胞因子、激素、细胞表面受体、胞质蛋白和核蛋白、代谢酶、受体配体、粘附蛋白、内体相关蛋白、四次穿膜蛋白(tetraspanins)、脂筏相关蛋白、抗原等
b.RNA种类:mRNA、miRNA、tRNA、rRNA、siRNA、和lncRNA以及其他可能的RNA种类
c.DNA:线粒体DNA(mtDNA)、单链DNA(ssDNA)、双链DNA(dsDNA)
d.脂质:胆固醇、鞘磷脂、己糖神经酰胺等
e.凝集素、多糖、蛋白聚糖、糖蛋白。
细胞外囊泡是携带上文提及的可溶性物质和不溶性物质的货物的膜结合颗粒。术语“细胞外囊泡”是指多种种类的分泌的或脱落的囊泡的组。这些被分为以下亚型(Xu等JIC2016):
1.微囊泡或脱落微囊泡;大小范围–50nm-1500nm
2.外泌体;大小范围–30nm–120nm
3.囊泡;大小范围<500nm
培养培养基或扩增培养基是其中hOMSC被培养和扩增的培养基。根据本发明的一些实施方案的培养培养基/扩增培养基包含至少一种以下组分:低葡萄糖Dulbecco改良的Eagle培养基(LGDMEM)、链霉素、青霉素、庆大霉素、两性霉素B、谷氨酰胺和血清,例如胎牛血清(FCS)。

实施例
下文描述的结果部分地从源自为口腔的口腔粘膜内衬的组成部分的人类牙龈的固有层(不包括上皮部分)的细胞群体的分泌蛋白质组获得。从腭和牙槽粘膜(alveolarmucosa)分离的hOMSC展示出相同性质。
hOMSC分离和培养
如上文和WO 2008/132722中描述的,从口腔粘膜活组织检查,特别是从来自25岁-80岁的供体起源的牙龈的活组织检查获得hOMSC。
简而言之,如由Marinka-Kalmani等2010(同上)描述的,牙龈或牙槽粘膜活组织检查3-4×2×1mm被切碎,并且将外植体培养在25cm2组织培养瓶中在补充有100μg/ml链霉素、100U/ml青霉素(Biological Industries,Beit-Haemek,Israel)、2mM谷氨酰胺(Invitrogen)和10%胎牛血清(FCS)(Gibco)的低葡萄糖Dulbecco改良Eagle培养基(LGDMEM)中。该培养基被称为培养培养基或扩增培养基。在一些情况下,链霉素和青霉素被庆大霉素代替,并且两性霉素B也包含在扩增培养中。
分泌蛋白质组产生
在扩增培养基中扩增的具有5倍-80倍之间的积累群体的hOMSC的培养物被用于产生hOMSC分泌蛋白质组。去除扩增培养基,并且用PBS彻底洗涤培养物,并且然后添加基础培养基或LGDMEM。在24小时-120小时后,收集培养基并且离心以去除任何死亡的细胞。上清液包含分泌蛋白质组。
可以通过使用本领域已知的设计和方法将上清液浓缩来增加分泌蛋白质组组分的浓度。如本文示出的,根据一些实施方案,可以设计范围从1.1倍-10,000倍的浓度比以可用于并且有效用于实现期望的治疗效果。
蛋白和分子水平上的阵列分析指示,hOMSC分泌蛋白质组具有之前尚未在源自其他来源包括皮肤源性干细胞和骨髓源性干细胞的干细胞分泌蛋白质组中被发现的独特组成特征。
分泌蛋白质组组成可以通过使hOMSC经受多种培养条件和刺激来改变。这样的培养刺激和条件的实例包括但不限于:
·化学的:例如低氧、高氧、化学药物、多种类别的化学刺激剂或抑制剂或多种途径、低离子浓度或高离子浓度例如Ca++和/或葡萄糖、多种化学药物如他汀类(statins)、双膦酸盐等;
·物理的:例如超声波、机械振动、电刺激、连续或间歇应变、光、辐射;
·底物:例如附着蛋白、三维基质、用于悬浮细胞培养物的珠;
·生物制品:例如生长因子、细胞因子、激素刺激、分化因子、DNA和RNA种类、遗传操纵。
实施例1.hOMSC与那些或其他来源的干细胞标志物的比较
如先前描述地(Marynka-Kalmani等2010和WO 2008/132722)获得hOMSC。通过酶消化从8日龄婴儿的包皮分离包皮SC(hSkin SC)。使两种细胞类型生长在T-75细胞瓶中在补充有必需氨基酸、抗生素和胎牛血清的低葡萄糖DMEM中。
通过RT-PCR和免疫化学评估hOMSC和包皮干细胞(hSkin SC)的干细胞标志物(Marinka-Kalmani等2010,同上和未发表的数据)。
如图1中示出的,hOMSC被赋予比hSkin SC更高的多能性相关标志物和神经嵴相关标志物的表达。
标志物OCT4、SOX2和NANOG是特征性多能性相关标志物;c-MYC和KLF4二者是多能性相关标志物和早期神经嵴标志物;并且SNAIL是特征性神经嵴干细胞标志物。
分子数据通过用针对多能性相关干细胞标志物和神经嵴相关干细胞标志物的抗体免疫荧光染色在蛋白水平上确认。指示标志物NANOG、SOX2、C-MYC、KLF4和SNAIL在hOMSC中比在hSkin SC中更丰富。还发现hOMSC中的染色限于核,表明这些转录因子的功能活性。因此得出结论,这些标志物在hOMSC中存在与hSkin SC相比明显更高的表达。
实施例2.hOMSC分泌蛋白质组的整体分析
hOMSC分泌蛋白质组的独特特征通过确定它的蛋白和核酸内容物确认。使用三种不同方法来获得广谱的hOMSC分泌蛋白质组组分:蛋白阵列、质谱(MS)和微小RNA(miRNA)表征。
如上文描述的,在扩增培养基中产生hOMSC并扩增。通过质谱和通过商购可得的蛋白阵列试剂盒评估条件培养基中的蛋白的谱。包含在hOMSC分泌蛋白质组内的RNA种类的测序使用本领域已知的方法进行以确定hOMSC分泌蛋白质组的遗传货物。
蛋白的谱
通过MS和蛋白阵列分析hOMSC分泌蛋白质组的蛋白内容物。
MS分析:如上文描述地制备来自4种不同hOMSC培养物(每一种源自单独的供体)的4种分泌蛋白质组。0.1ml样品被胰蛋白酶消化,通过LC-MS/MS在Q exactive plus(ThermoFisher)上分析,并且通过Discoverer软件1.4版针对人类和牛uniprot数据库(对于胎牛血清)分析。使用靶-诱饵策略针对肽水平和蛋白水平上的错误发现率(FDR)<0.01过滤鉴定出的蛋白。
将蛋白过滤以消除常见的污染物和单肽鉴定(single peptideidentification)。通过计算每一种肽的峰面积完成半定量。蛋白的面积是来自每一种蛋白的三种最强肽的平均值。
在hOMSC分泌蛋白质组内鉴定出总计369种蛋白(图11),包括细胞外基质蛋白、糖蛋白、蛋白受体、针对细胞外基质蛋白的蛋白水解酶和蛋白水解酶抑制剂、参与代谢的蛋白、参与应激响应的蛋白诸如热休克蛋白、核蛋白、参与组织发育和修复的蛋白、整合细胞膜蛋白(integral cell membrane protein)如整合素以及包括外泌体标志物CD63的分化(CD)蛋白的簇、免疫调节蛋白和其他蛋白的簇。
值得注意的是参与神经系统的内稳态、保护和修复的13种蛋白的簇,在表1中详细描述:
表1.参与神经系统的内稳态的hOMSC分泌蛋白质组蛋白。
令人特别感兴趣的是hOMSC分泌蛋白质组中存在SOD1和中脑星形胶质细胞源性神经营养因子(MANF)。这些蛋白抑制细胞内应激,细胞应激为神经退行性疾病的标志和细胞死亡的原因。此外,已经显示出MANF在动物模型中治疗帕金森病是有效的(Voutilainen等2015)。
如通过MS确定的,hOMSC分泌蛋白质组的蛋白组成是独特的。当hOMSC分泌蛋白质组与源自人类骨髓(BMSC)、脂肪组织(ASC)或牙髓(DPSC)的间充质干细胞的分泌蛋白质组比较时(Tachida等2015),发现hOMSC分泌蛋白质组包含未在任何分泌蛋白质组中检测到的75种蛋白。
鉴定出的75种独特的蛋白在表2中列出。

蛋白CXCL12是hOMSC分泌蛋白质组特有的,已知在干细胞募集到受损的器官中起作用并且促进神经祖细胞的增殖和迁移(Wu等2009)。这种蛋白在hOMSC分泌蛋白质组中高度丰富,在369种蛋白中排在第58位,即在检测到的蛋白的前20%。
周围组织在由疾病或损伤引起应激时分泌CXCL12以从骨髓募集内皮祖细胞和间充质干(基质)细胞。该过程在受损的糖尿病组织中被基本上抑制(Rodrigues等2015、Tepper等2010)。包含作为受损的组织处的主要营养因子的CXCL12的hOMSC分泌蛋白质组的施用,通常促进伤口愈合并且特别是促进糖尿病个体中的伤口愈合。
如图12中示出的,总计294种hOMSC分泌蛋白质组蛋白是与关于源自BMSC、ASC或DPSC的分泌蛋白质组所列出的1534种蛋白共有的。然而,分泌蛋白质组的独特特征不仅通过它的组分,还通过这些组分的相对丰度来确定。例如,胰岛素生长因子2(IGF2)(属于生长因子的胰岛素家族并且在组织内稳态和修复中具有多效功能)是hOMSC分泌蛋白质组的主要组分,但在BMSC中几乎未检测到并且在ASC和DPSC中未检测到。
蛋白阵列:通过80种蛋白的蛋白阵列试剂盒(G-Series CytokineArray,RayBiotech,Inc,USA)进一步分析hOMSC的分泌蛋白质组的蛋白组分并且与hSkinSC的分泌蛋白质组的蛋白组分进行比较。蛋白分析揭示了至少21种蛋白的分泌的差异,所述至少21种蛋白在hOMSC分泌蛋白质组中与hSkin SC的相比过表达或表达不足(图2和3)。值得注意的是在hOMSC中,与hSkin SC中相比,蛋白PlGF、MSCF、VEGF和HGF是过丰富的细胞因子,并且蛋白瘦蛋白、ENA-78和MCP-3丰度不足。
hOMSC和hSkin SC的分泌蛋白质组还与已发表的源自年轻人类骨髓的人类间充质干细胞的分泌蛋白质组进行比较,所述已发表的源自年轻人类骨髓的人类间充质干细胞的分泌蛋白质组使用与上文描述的(Park等2009)被用于确定hOMSC和hSkin SC的分泌蛋白质组的相同抗体阵列试剂盒。考虑到检测下限值为50,图2和4中的表的比较显示出,如PlGF、EGF、SDF-1、BDNF、GDNF、IGF1、血管生成素和许多其他的生长因子和神经营养剂在骨髓源性间充质干细胞的分泌蛋白质组中是检测不到的,但在hOMSC中表达。
因子和剂中的一些,诸如,例如,HGF,在hOMSC中高度表达。hOMSC分泌蛋白质组和皮肤SC的分泌蛋白质组之间的差异在图3中示出,图3图示了hOMSC分泌蛋白质组和皮肤SC分泌蛋白质组内的多种趋化因子的量之间的比例。图1-4中展示的数据清楚地证明,3种干细胞类型具有与测试的蛋白不同的分泌谱。
微小RNA分析:条件培养基从三种不同hOMSC培养物(每一种源自不同的供体)收集,如上文描述地用于制备分泌蛋白质组,但不进行浓缩步骤。将条件培养基在4℃以12000G离心4分钟,根据下文的程序提取总miRNA:
1.将7ml的TrizolTM试剂添加到10ml的样品并且涡旋。然后将样品在室温放置静置5分钟。
2.添加1.4ml的氯仿并且将样品剧烈摇动15秒。
3.将样品在4℃以15,300G离心15分钟。
4.将上层水相转移到新管,小心地避开中间相。
5.按照制造商的方案,使用mirVanaTMPARIS miRNA分离试剂盒分离miRNA。mirVanaTM试剂盒利用两个连续的GFF。
将miRNA洗脱在50μl无RNA酶的水中。
使用NanoDropTM光分光光度计(NanodropTechnologies,Willmington,DE,USA)评估miRNA的浓度和纯度。如表3中示出的波长依赖性的消光系数代表溶液中所有RNA的微组分:
表3.波长依赖的消光系数值
样品编号 | ng/μl | 体积(μl) | 260/280nm处的消光系数 |
1 | 38.5 | 17 | 2.11 |
2 | 30.9 | 17 | 2.15 |
3 | 40.7 | 17 | 2.1 |
微小RNA表达的表征
miRNA表达谱分析(profiling)使用nCounter miRNA表达测定(在https://www.nanostring.com中描述)进行,该测定提供了一种用于检测800个miRNA的方法,而不需要使用逆转录或通过使用被称为nCounter报告物探针的分子条形码扩增。所有数据分析和归一化使用nSolverTM软件分析(从NanoString Technologies免费下载)进行,其中特定的miRNA计数针对基于跨越所有实验样品或使用加标(Spike-in)对照计算的CVS统计量的稳定表达的miRNA的选择进行归一化。
表4中示出的归一化数据指示39种miRNA在各自源自不同的供体的3种hOMSC分泌蛋白质组中表达。该miRNA中的每一种具有高于20的相对表达值,当使用上文描述的方法学时,其是公认的用于miRNA检测的较低阈值。
表4.在3种独特的hOMSC分泌蛋白质组中鉴定出的具有>20的相对值的miRNA。
将这39种miRNA的谱与骨髓源性间充质干细胞(BMSC)和脂肪源性间充质干细胞(ASC)的已发表的miRNA的谱(Baglio等,2015)比较。结果证明hOMSC分泌蛋白质组miRNA谱是独特的。hOMSC分泌蛋白质组miRNA与BMSC分泌蛋白质组和ASC分泌蛋白质组中检测到的miRNA之间分别仅共享5种和3种miRNA。由hOMSC分泌蛋白质组和BMSC分泌蛋白质组共享的5种miRNA中的3种还与ASC分泌蛋白质组共享。因此,34种miRNA不包含在被认为赋予高治疗能力的成体BMSC分泌蛋白质组和ASC分泌蛋白质组的miRNA组成内。
实施例3.hOMSC在伤口愈合中的治疗能力
糖尿病患者中的伤口愈合由于受损的局部和全身信号传导以及对伤口愈合信号(cue)的不适当组织响应而被延迟。这种多因子受损的伤口愈合过程带来了延迟的细胞迁移,降低的新血管和结缔组织形成。干细胞因为其多因子分泌蛋白质组已经被提出作为用于治疗糖尿病伤口的前沿工具。
缺乏瘦蛋白受体、增加了食物摄取并且因此变得肥胖并且发展II型糖尿病的转基因小鼠(db/db小鼠)因具有与人类中的II型糖尿病相似的疾病病原学而被使用。在小鼠中的其他已知糖尿病模型中,糖尿病db/db小鼠展示出最慢的皮肤伤口闭合的速率(MichaelsJ等2007)。
在糖尿病(血糖>300mg/dcl)db/db小鼠的背上进行直径为6mm的全层皮肤损伤(Full thickness dermal wound)。将具有8mm的内径的硅圈形环缝合在伤口周围以防止伤口收缩,并且用作标准参考对象以在宏观水平计算伤口闭合的速率。将动物分成3组,每一组5只-10只动物:i)用充当细胞递送的媒介物的PBS注射的阴性对照组;ii)hOMSC治疗的组;和iii)hSkin SC治疗的组。细胞在4个等距离部位处皮内注射,5×105个细胞/部位。每2天-4天给动物拍照以确定伤口闭合的速率。为此,通过对照片的图像分析来确定每一个时间点每一只动物中的伤口面积,并且通过确定由在相同照片上出现的圈形环的内圆周所描绘的面积来归一化伤口面积(图5)。
图6A(定量结果)和6B(代表性定性照片)中证明的结果指示,与未治疗的(PBS媒介物)或hSkin SC治疗的动物相比,hOMSC治疗的动物中直到伤口闭合之前的伤口愈合速率是统计学上显著(p<0.05)更高的。用hOMSC治疗的所有动物中伤口闭合发生在受伤后16天,而未治疗的组的所有动物中伤口完全闭合发生在受伤后26天。此外,在未治疗的组和hSkinSC治疗的组之间没有观察到显著的统计学差异。
在一项单独的研究中,还在健康的未治疗的野生型(WT)动物中测试了伤口愈合的自然速率。出于该目的,使用了与上文描述相同的实验设置。动物与它们的db/db对应物年龄匹配。
如图7中描绘的,在hOMSC治疗的小鼠中,伤口愈合的速率与该WT-未治疗的小鼠相似。在用hOMSC治疗的db/db糖尿病小鼠中,伤口完全闭合的平均时间为14.3±1.4天,WT-未治疗的动物的伤口完全闭合的平均时间为15.14±1.06天,并且db/db糖尿病未治疗的小鼠的伤口完全闭合的平均时间为22.75±2.16天。这些数据指示出,hOMSC具有克服糖尿病状态对伤口愈合的有害影响并且将糖尿病伤口愈合的速率逆转至正常的能力。
hSkin SC缺乏对糖尿病伤口愈合的刺激作用是出乎意料的,并且因此在相同的实验设置中测试了另一种SC群体即脂肪组织源性干细胞(hADSC)的能力。图8和图9中示出的结果证明,hADSC治疗的动物中伤口愈合的速率比hOMSC治疗的动物中伤口愈合的速率统计学上显著更低,但高于未治疗的动物或hSkin SC治疗的动物的伤口愈合的速率(p<0.05)。尽管如此,在所有用hADSC治疗的动物中,与用hSkin SC治疗的动物一样,伤口完全愈合发生在受伤后24天。
因此得出结论,在促进糖尿病伤口愈合中,幼稚hOMSC优于其他干细胞。
实施例4.hOMSC分泌蛋白质组的治疗潜力
为了测试hOMSC的治疗作用是否至少部分归因于它们的独特分泌蛋白质组,将1×106个hOMSC在无血清培养基中维持24小时。
然后,收集培养基并且用具有1,000道尔顿的截止值(cutoff)的浓缩过滤器(Amicon)浓缩。浓缩的培养基包含幼稚hOMSC的分泌蛋白质组的组分,如通过MS分析的。将这种hOMSC来源的浓缩的条件培养基注射到实施例2和图5中描述的糖尿病伤口愈合模型中。每一只糖尿病db/db小鼠在图5中由箭头标记的每一个部位处用50μl的条件培养基(代表24小时的时间段内分泌2×105个hOMSC)注射。因此,将总计200μl的浓缩的条件培养基注射到每一只动物的伤口周围。条件培养基的施用仅在实验时间段开始时进行。如上文描述的,肉眼追踪动物并且在闭合时处死。包括硅环的伤口区域被取出并且进行组织学分析。
伤口闭合的速率在图10中示出。结果指示,一次性施用限于浓缩的hOMSC条件培养基内的hOMSC-分泌蛋白质组与hOMSC一样有效促进糖尿病伤口愈合。愈合的伤口的中央的血管的数目和胶原蛋白的量的组织形态计量分析(histomorphometric analysis)揭示:i)hOMSC治疗的动物和hOMSC分泌蛋白质组治疗的动物中的胶原结缔组织的量之间无统计学差异;和ii)hOMSC分泌蛋白质组治疗的动物中的血管的数目与未治疗的动物或hSkin SC治疗的动物相比增加,并且血管的数目与hOMSC治疗的动物相比降低。
不希望受任何理论或作用模式的约束,揭示了与用会继续分泌物质的干细胞治疗相比,用分泌蛋白质组的继续或多次治疗将是需要的。尽管如此,分泌蛋白质组组合物比细胞更安全并且更易于操纵、表征、维持和施用。
总之,结果指示hOMSC分泌蛋白质组保持了hOMSC促进糖尿病足部溃疡的愈合的效率,并且因此它们可以被用作独立的治疗工具或作为用于细胞疗法的辅助物,特别是在需要新生血管形成的任何时候。
以上具体实施方案的描述将如此完全地揭示本发明的一般性质,使得其他人可以通过应用现有的知识,容易地为多种应用修改和/或调整这样的特定实施方案而不需要过度实验并且不背离一般概念,并且因此,这样的调整和修改应当并且意图被包含在本公开的实施方案的等同物的含义和范围内。应理解的是,本文采用的措辞或术语是出于描述并且非限制的目的。用于实施多种本公开的功能的手段、材料和步骤可以采取多种替代形式而不背离本发明。
