Watch As Researchers Create Beating, 3D Printed Heart Organoid

They call them “organoids,” and they’re 3D printed, beating cardiac cells which are sure to inspire scientists and biologists while raising ethical concerns among critics intent on stopping the progress of the technology.

The groundbreaking research program aimed at creating human organs is the result of a project at the Wake Forest Baptist Medical Center Institute for Regenerative Medicine, and it features heart cells which are made functional and shaped using a highly-specialized 3D printer.

Bioprinting Solutions & Dreams: an Interview with 3D Bio’s Dr. Vladimir Mironov

This was may day so far: I wrote about an amazing new development in the adoption of 3D printing for surgery in Italy, an incredible new 3D printing technology developed by a graduate student in Buffalo, and a stunning “smart doll” created by a self-described gaijin (non-Japanese person) in Japan. Only a couple of years ago, this would be science fiction. Instead, to top it off, here I am enjoying the sunset with a Campari Spritz, writing about my interview with Vladimir Mironov, the scientist behind most of the work at Russia’s 3D Bioprinting Solutions (3D Bio for short).

Organovo Describes First Fully Cellular 3D Bioprinted Kidney Tissue

SAN DIEGO, April 1, 2015 /PRNewswire/ — Organovo Holdings, Inc. (NYSE MKT: ONVO) („Organovo“), a three-dimensional biology company focused on delivering breakthrough 3D bioprinting technology, presented data on the company’s in vitro three-dimensional kidney tissue at the 2015 Experimental Biology conference in Boston, Massachusetts.

„Kidney represents an ideal extension of Organovo’s capabilities to 3D bioprint organ tissues that can be tremendously useful in pharmaceutical research,“ said Keith Murphy, Chairman and Chief Executive Officer at Organovo. „The results released today admirably demonstrate a proof of concept that kidney is on the way to becoming another core commercial tissue for Organovo. The product that we intend to build from these initial results can be an excellent expansion for our core customers in toxicology, who regularly express to us an interest in having better solutions for the assessment of human kidney toxicity.“

For the first time, fully human kidney proximal tubular tissues have been generated that are three-dimensional, and consist of multiple tissue-relevant cell types arranged to recapitulate the renal tubular / interstitial interface. The tissues are fabricated using Organovo’s proprietary NovoGenTM bioprinting platform, and will ultimately join the company’s exVive3DTM Liver tissues to expand the repertoire of physiologically-relevant tissue systems available for toxicity and efficacy testing as well as disease modeling. Dr. Sharon Presnell, Chief Technology Officer and Executive Vice President of Research and Development, stated, „Our bioprinted human kidney tissue represents a significant technical advance over the simple monolayer cell line cultures that predominate today. The histologic and functional features of the initial prototypes are compelling, and the in vitro durability of the system will likely enable the assessment of drug effects at chronic, physiologically relevant doses. Furthermore, the cellular complexity of the system will likely support mechanistic investigations into drug responses, including end points that have been difficult or impossible to assess in vitro, including tubular fibrosis and post-injury recovery.“

Key findings and attributes from Organovo’s research include:

3D Bioprinting Human Chondrocytes with Nanocellulose-Alginate Bioink for Cartilage Tissue Engineering Applications

The introduction of 3D bioprinting is expected to revolutionize the field of tissue engineering and regenerative medicine. The 3D bioprinter is able to dispense materials while moving in X, Y and Z directions; enabling the engineering of complex structures from the bottom up. In this study a bioink that combines the outstanding shear thinning properties of nanofibrillated cellulose (NFC) with the fast crosslinking ability of alginate was formulated for the 3D bioprinting of living soft tissue with cells. Printability was evaluated with concern to printer parameters and shape fidelity. The shear thinning behavior of the tested bioinks enabled printing of both 2D gridlike structures as well as 3D constructs. Furthermore, anatomically shaped cartilage structures, such as a human ear and sheep meniscus, were 3D printed using MRI and CT images as blueprints. Human chondrocytes bioprinted in the non-cytotoxic, nanocellulose-based bioink exhibited a cell viability of 73% and 86% after 1 and 7 days of 3D culture, respectively. Based on these results we can conclude that the nanocellulose-based bioink is a suitable hydrogel for 3D bioprinting with living cells. This study demonstrates the potential use of nanocellulose for 3D bioprinting of living tissues and organs.
