安阳市人民医院激光去掉雀斑多少钱One step further towards organ regeneration.A Chinese biotechnological company claims to be have created the world’s first 3D blood vessel bio-printer, which could pave the way, in theory, to producing personalised, functional organs. One of the major stumbling blocks in tissue engineering is supplying artificial tissue with nutrients, and scientists around the world have been working for years on trying to create artificial blood vessels.向器官再生又迈进了一步。中国生物科技公司声称已经制造了世界上第一台3D血管生物打印机,理论上讲这为制造个人化功能器官铺平了道路。组织工程中主要的障碍之一是向人工组织提供营养,世界各地的科学家已经工作多年试图制造人造血管。With two nozzles working alternately, this bio-printer can finish a 10-centimeter blood vessel within two minutes.两只喷嘴交替工作,这种生物打印机可以在2分钟内制造一根10厘米的血管。The core of the printer is the BioBrick, in which there are stem cells. Given certain environments and certain conditions, stem cells can, according to our needs, differentiate into the cells we need.打印机的核心是生物砖,其中有干细胞。在特定的环境和条件下,干细胞可以根据我们的需要分化成我们需要的细胞。At the heart of the technology is a stem cell culture system that consists of seed cells and bio-inks filled with growth factors and nutrients. When combined with other materials, the 3D bioprinter creates layered cell structures that can be cultivated to form tissues with physiological functions.技术的核心是一个干细胞培养系统,包括种子细胞以及充满生长因子和营养物资的生物油墨。当与其它材料结合,3D生物打印机产生分层的细胞结构,能培养出具有生理功能的组织。The achievement here in producing a 3D blood vessel bio-printer is not just that we can print a blood vessel, but we have found a way of keeping vascular cells and other substances active. The method can be used to print blood vessels, but also livers, kidneys and other organs.3D血管生物打印机的成果不仅仅能打印血管,而且我们找到了一种使血管细胞和其它物质保持活性的方法。这种方法不仅能用于血管打印,也可用于肝、肾等器官的打印。While the prospect of a 3D-printed kidney, liver or heart remains years off, as creating entire organs involves work that is impossible today, the good news is that 3D printing does have the potential to help patients today in many other ways.尽管3D打印肾脏、肝脏或心脏的愿望仍然遥远,在尚不能完整制造器官的今天,好消息是3D打印在其它许多方面具有帮助病人的潜力。译文属。 /201511/407569 Max is one of the most successful search and rescue dogs in the country.马克斯是国内最优秀的搜救犬之一。He knows what hes doing.
