专家:器官冻存都未成功 所谓人体冻存更近遗体保存

2017-08-15 09:34:11   中国青年网

据媒体报道,5月初,中国开展了首例人体冷冻操作。

49岁的癌症患者展文莲去世后,她的遗体被山东银丰生物工程集团和山东大学齐鲁医院的临床工作人员程序性降温,最终用液氮冻存。

桂军民是展文莲的丈夫,他期待妻子有一天能醒过来。他本人未来也希望加入这个名为“生命延续计划”的人体冷冻实验。

中科院理化技术研究所研究员、低温生物医学工程学北京市重点实验室主任刘静告诉澎湃新闻,人体冻存是低温医学的终极目标,但目前的人体冻存还主要是一种商业行为或尝试:只负责“冷冻”,不负责“复活”。

中国科学院院士朱作言告诉澎湃新闻,据他所知,目前除了成功冷冻细胞或极早期胚胎外,冷冻果蝇、鱼等实验动物,都没有听说有成功的先例。

刘静认为,现阶段的人体冻存更接近于一种遗体保存服务。乐观地说,随着未来新科技的涌现,打破人体冷冻的技术难题,从而实现复苏、存活,也并非一定不可能,但需要艰苦卓绝与极具创新的科学探险。如果攻克这一技术难题,将是人类最重大的科技突破之一。人类将因此突破年龄的限制,实现星际旅行;并“任意切换”,应用在永葆青春以及对抗疾病等方面。

目前组织或者器官的冷冻保存极其困难

刘静表示,低温是一把“双刃剑”,它既可以保护生物体,也可以摧毁生物体。

据刘静介绍,利用现代低温冷冻保存技术,人们已经成功冻存了很多种类的细胞,如成纤维细胞、脂肪细胞、肿瘤细胞、干细胞,以及精子和卵母细胞。

液氮是细胞冻存过程中最常用的超低温制冷剂,在有毒有机溶剂的保护下,细胞能够长期被保存。

但复苏的成活率,因细胞而异。

备受人们关注的冷冻卵子技术,冻存的就是女性的生殖细胞——卵母细胞。其冻存后,细胞复苏成功率甚至低于50%。

刘静表示,原因之一可能是,卵母细胞的尺寸远大于其他普通细胞。

除了细胞,人们在皮肤、角膜、肝脏、肾脏等复杂组织和器官的短期保存上也取得了一定进展,但长期保存技术有待进一步突破。
