Stem Cells Origami Organs

Posted by davids@stemsave.com on May 3, 2019 1:30:00 PM

The American Chemical Society (ACS) has published a study that uses 3D printing to create organ frames that can be populated with cells to resemble fully fledged organs. The researchers used a structural sugar called cellulose that plants, archaea and some bacteria use for structural support in their cells. This structural component is also used in making paper, and it is therefore easy to store for prolonged periods of time and inexpensive to produce. Additionally, since cellulose structures are easy to manipulate, the researchers were able to create channels resembling blood vessels, which they then populated with human epithelial cells that typically line blood vessels.

3D Printing Tissues with Stem Cells

Posted by maxi@stemsave.com on Apr 10, 2019 11:47:00 AM

Researchers at UC Berkeley have been working on improving and scaling up and the printing of biomaterials with stem cells. They have developed a unique approach to ‘3D’ bioprinting by incorporating flash freezing into their process. They have improved on current techniques by printing layers of flat tissues [2D] and freezing them until they can be combined into a 3D structure. This technique was developed to overcome one of the major hurdles in scaling up 3D printing: the survival of the printed cells during the lengthy process of printing complex structures. By using 2D layers and flash freezing them before bringing them together to form a 3D organ or tissue structure, the new technique assures the survival of the cells throughout bigger, and more complex organs.

Stem Cell Bio-Printing Advances with Ultrasound

Posted by devin@stemsave.com on Apr 4, 2019 10:59:00 AM

Researchers at North Carolina State University, led by Assoc. Prof. Rohan Shirwaiker, have created a method to “herd” stem cells into desired structures using a biological 3D printer to create specialized structures more easily, overcoming one of the major hurdles in biological 3D printing. While researchers rely on biological scaffolds to help the stem cells differentiate into a particular organ or tissue, this new technique gives the researchers more control in guiding the cells into the desired structure.
