细胞存储的意义
许多研究表明,许多不同类型的成体干细胞和再生细胞的数量和功能随着年龄的增长而下降1-4。研究表明,患者的ADRCs在被称为冷冻保存的过程中被冻存得越早,在未来用于医疗使用时会表现出潜在的更大的潜能性5。这些用途可能包括重建手术5,心血管疾病治疗6,胃肠道疾病的治疗7以及许多其他与年龄相关的病症,与此相关的人类临床试验正在计划和开展中。
衰老被认为与我们身体的干细胞和再生细胞的老化有关8。随着它们的老化,干细胞和再生细胞再生或修复受损组织的能力逐渐受到损害,并且与老化症状直接相关,例如伤口愈合的能力降低,肌肉量减少,骨密度降低,心脏扩大以及血管弹性降低。
普遍认为,液氮中的冷冻保存细胞停止其衰亡过程并保持其年轻的性质9。在液氮温度-196℃时,细胞的活性将无限期地保留9,10。现在存储自己的ADRCs会允许您在将来需要的时候使用这些更年轻,更有活力的细胞。

脂肪组织是丰富的干细胞和再生细胞来源
人体脂肪组织是干细胞和其他细胞类型的公认来源,据信这些细胞集体有助于损伤或耗氧的组织和器官的愈合,修复和再生1。 这些细胞驻留在大的球状脂肪细胞之间的间隙中。 从脂肪组织中释放来自脂肪的干细胞和再生细胞(ADRCs)准备将它们立即使用或冷冻储存以备将来使用。
在2001年2,ZUK等第一次证明了从脂肪组织中分离的某些特定细胞形成其他组织如肌肉,软骨,骨骼等细胞的能力。今天,基础和应用研究的整个领域已经开始蓬勃发展。本研究的目的是探索ADRCs如何用于治疗各种与衰老相关的人类疾病。

StemSource®细胞存储常见问题

1. 什么是脂肪来源的干细胞和再生细胞(ADRCs)?
脂肪干细胞和再生细胞(ADRCs)由(1)成体干细胞,(2)内皮祖细胞(形成血管的细胞)组成,和(3)其他被认为促进愈合,修复 ,以及受损或耗氧的组织和器官的多种再生细胞类型。 这些细胞类型与再生细胞(如骨髓,骨骼肌,胚胎和胎儿组织)的其他来源相比具有实际的优势。 例如,ADRCs可以大量获得,发病率低,无细胞培养。 此外,来自患者自身脂肪组织(自体使用)的ADRCs没有已知的排斥或疾病传播的风险,并避免了伦理问题。
2. 现今,脂肪来源的干细胞和再生细胞(ADRCs)在医学中有何用途?
目前,没有MHLW批准的ADCRCs使用。 然而,这些细胞和相关细胞已被用于许多临床研究。 ADRCs已被用于治疗颅骨1的缺陷,治疗辐射诱发的损伤2,癌症治疗后的乳房重建3,骨髓移植4-7治疗GVHD和排斥反应,以及治疗与炎性肠病相关的瘘8-10。 此外,ADRCs也被用于荷兰和西班牙的心脏病临床试验26。近期临床研究表明,ADRCs治疗男性勃起功能障碍安全和有效27,28。
3.脂肪来源的干细胞和再生细胞(ADRCs)在未来可能有哪些类型的临床应用?
除了已经在临床研究中使用的应用之外,许多临床前研究已经证明了脂肪来源干细胞和再生细胞在临床治疗中的巨大前景。例如,由东京国立癌症中心研究所的Takahiro Ochiya博士领导的小组已经表明,脂肪来源的干细胞可以分化成具有肝细胞(肝细胞)12的特性的细胞,其可以促进啮齿动物肝损伤后的愈合。 其他研究人员发现,ADRC在中风后的中枢神经系统13,14和脊髓损伤15,肌肉疾病16,肾损伤17,尿失禁18,肺损伤19,20,关节炎21,椎间盘疾病22,糖尿病23,和男性勃起27,28等疾病中的潜在价值。
4.什么是干细胞和再生细胞银行?
细胞库使用专有的用于处理人类脂肪组织的StemSource®系统来准备细胞进行冷冻保存。该系统使用MHLW批准的自动化设备和单次使用的耗材元件,旨在保护每个患者的细胞免受于接触任何外源性物质。条形码标签和集成数据系统确保每个患者的细胞保持安全和确保仅供该患者使用。研究证明,在非常低的温度(冷冻保存)下长时间地存储许多细胞类型的细胞悬浮液而不损失细胞活力已经被证明。例如,冷冻保存的骨髓和脐带血常常用于治疗白血病和某些遗传性疾病。类似地,冷冻保存人类卵母细胞和精液已经用于治疗不孕症多年。StemSource®Bank程序采用相似的方法实现对脂肪来源的再生细胞的低温保存。
5. 我的再生细胞在哪里和如何进行保存?是安全的吗?
实施细胞存储的机构和医院会配备StemSource®细胞存储设备。这些细胞存储设备是最先进的设计,旨在保护您存储细胞的安全性和完整性。通过液氮的缓慢蒸发使细胞保持冷冻状态,该技术不需要电力。因此,即使在持续数天的电力中断的情况下,您储存的细胞仍将保持在安全的存储温度。与其他细胞类型的研究表明,冷冻保存细胞的临床效力保持多年24,25,理论上是无限期保持活性26。
6.需要吸取多少体积的脂肪组织供干细胞和再生细胞的存储?
脂肪组织中实际包含的干细胞和再生细胞因人而异,我们建议吸取100~250mL脂肪组织用于存储。
7.脂肪来源干细胞和再生细胞可以保存多长时间?
冷冻保存过程使细胞活性处于暂停状态,这种情况下细胞可以无限期地保持其细胞活性。
