The natural world. Looking pretty for 3.5b years.

3D Hearts

Author: Guest Writer/Tuesday, February 5, 2013/Categories: Uncategorized

Here at Riled Up we normally focus on telling stories about environmental matters, natural history, and the wonder of exploration. However, occasionally a new technological advance occurs that requires very close attention. Researchers Heriot-Watt University in Scotland have produced one such technological breakthrough with the development of living tissues from embryonic stem-cells using 3D printing machines.

3D printing has increasingly been used in industries ranging from clothing fabrication, to architectural modeling, and even in candy creation. The novel process creates three dimensional objects from a digital design and then builds the resulting object layer by layer with a material  laid down by the 3D printer's jets. Using human embryonic stem cells (hESC's), having the potential to become any type of tissue in the body, a 3D printer has constructed living tissues from the cells. Such a constructed bio-material fabric has the potential to replace damaged hearts, lungs, kidneys or other organs for transplantation into ailing patients.
In the longer term, this new method of printing may also pave the way for incorporating hESCs into artificially created organs and tissues ready for transplantation into patients suffering from a variety of diseases.

 Dr. Will Shu, one of the lead researchers on the project, said: "We found that the valve-based printing is gentle enough to maintain high stem cell viability, accurate enough to produce spheroids of uniform size, and most importantly, the printed hESCs maintained their pluripotency - the ability to differentiate into any other cell type."


So let bio-engineering with 3D stem-cells expand and a revolution in regenerative medicine will follow.
