【芝加哥生物技术公司3D打印迷你心脏】据外媒报道,总部位于芝加哥的生物技术公司BIOLIFE4D宣布,它已经成功地使用来自患者的心脏细胞3D打印了一颗迷你心脏。这颗小巧的心脏结构与正常大小的心脏结构相同,该公司表示,这是推动创造人造心脏移植的重要里程碑。最终,该公司希望3D打印一个具备所有功能的正常大小的人类心脏。

Chicago biotech company 3D prints a mini human heart

BIOLIFE4D used patient-derived cardiac cells to 3D print the tiny heart.

The Chicago-based biotech company BIOLIFE4D announced today that it has successfully 3D-bioprinted a mini human heart. The tiny heart has the same structure as a full-sized heart, and the company says it's an important milestone in the push to create an artificial heart viable for transplant.

The heart was printed with patient-derived cardiac muscle cells, or cardiomyocytes, and bioink made from extracellular matrix compounds that replicate the properties of the mammalian heart. BIOLIFE4D first bioprinted human cardiac tissue in June 2018. Earlier this year, the company bioprinted individual heart components, including valves, ventricles and blood vessels. Its process involves reprogramming a patient's white blood cells into induced pluripotent stem cells (iPS cells), which can differentiate into different types of cells, including cardiac cells.

Eventually, the company hopes to bioprint a full-sized functioning human heart. Theoretically, bioprinted hearts could reduce or eliminate the need for donor organs. Of course, BIOLIFE4D isn't the only company looking to 3D print organs. Researchers at Tel Aviv University 3D printed a heartearlier this year. We've seen functioning 3D-printed silicone hearts, and bioengineers at MIT managed to 3D print complex vascular networks, like those necessary to sustain artificial organs.
