川大教授3D打印造血管 30只试验猴活存活率100%

2016-12-14 09:55:03   大河网

一个惊人数据

全球心脑血管疾病患病人数超过17亿人,占全球人口四分之一

一次成功实验

破解人工血管内皮化难题,每年至少有一亿人需要这样的技术

一项重大突破

科技成果转化成功案例,未来的三到五年内将会应用于人体

一生潜心积累

康裕建教授至少做了20年积累,投入的时间无法用长短来衡量

12月11日,3D生物打印血管植入恒河猴体内实验宣告取得成功,引发轰动。有分析认为,这标志着困扰临床半个世纪的人工血管内皮化问题成功找到解决办法,为全球超过17亿心血管疾病患者带来福音。

12日晚8点40分,华西都市报记者在成都一家酒店大堂见到了猴体实验的负责人,四川大学华西医院再生医学研究中心教授、蓝光英诺首席执行官兼首席科学家康裕建。彼时,他正在与两位分别从北京和成都赶来的专家探讨大健康产业的问题。年近六旬的他,脸上不免露出一丝疲态,偶尔也会摘下眼镜揉一揉脸部。

“我13日要赶到昆明,14日有一个大健康产业论坛,我要在论坛上做报告。”康裕建十分忙碌,在他的脸上,看不到多少成功的喜悦,有的只是一位科学家的严谨和坚毅。

实验意义

“开创了血管疾病治疗的新纪元”

截至2016年12月1日,已对30只恒河猴进行3D生物打印血管体内植入实验,实验动物术后存活率为100%。康裕建对自己的科研成果只有简单的三句评价。“这次实验的成功,开创了血管疾病治疗的新纪元。”康裕建说,人工血管已经出现了半个多世纪,但人工血管再堵塞的问题始终没有得到解决。

“3D生物打印血管彻底解决了人工血管内皮化的问题,不会发生再堵塞。”康裕建说,实验的第二个意义便是,“开启了3D生物打印在医学应用的新纪元”。康裕建说,实验成果的意义还在于,开创了干细胞领域的新方向。

根据世界卫生组织统计,2012年全球心脑血管疾病患病人数已经超过17亿人,占到了全球人口的四分之一。“现在从全球来看,每年至少有一亿人需要这样的技术。”康裕建告诉记者,在未来的三到五年内,将会应用于人体。
