中国四川科研团队取得医学里程碑突破：利用干细胞3D打印技术成功构建可自愈人工血管。该技术以患者自体干细胞为“生物墨水”，精准复刻天然血管的三层结构，打印精度覆盖6毫米以下微血管。更关键的是，人工血管具备“自我生长”能力，可随人体代谢修复，突破传统人工血管易血栓、排异反应强的局限。
这一成果为心血管疾病、创伤修复等领域提供全新解决方案——既缓解血管供体短缺困境，又通过“自体来源”降低免疫排斥风险，推动个性化医疗迈向临床应用。从技术原理到临床潜力，均彰显中国在生物医学工程领域的创新实力，为未来组织工程与再生医学发展开辟新路径。
A research team in Sichuan, China, has achieved a groundbreaking medical feat: developing self-healing artificial blood vessels via 3D bioprinting with stem cells. Using patients’ own stem cells as "biological ink," the technology precisely replicates the three-layer structure of natural blood vessels, with a printing resolution capable of fabricating microvessels smaller than 6 mm. Most innovatively, these artificial vessels can "self-grow" and regenerate with the human body, overcoming limitations of traditional vascular grafts (e.g., thrombosis, strong immune rejection).
This breakthrough offers novel solutions for cardiovascular diseases and trauma repair—it not only eases the shortage of vascular donors but also reduces rejection risks through "autologous sources," advancing personalized medicine toward clinical translation. From technical principles to clinical potential, it showcases China’s innovative strength in biomedical engineering, paving new paths for future tissue engineering and regenerative medicine.
