Biofabriquer, fabriquer la vie

A Paris-New York airliner is an exact replica of another Paris-New York airliner - including passengers - which landed more than four months ago. Among the three hypotheses put forward by Adrian and his team of scientists, there is bioprinting. “We 3D print biological material. "(L'Anomalie)

A Net tycoon is driven by a crazy ambition: to find a cure for death. To this end he brings together the best specialists. “The idea is to take your liver out and replace it with the same, exactly the same one, created from your own stem cells. No risk, no problem. In a day, it's folded." He said to one of his guinea pigs. (L'Invention des corps)

In two recently award-winning novels, one the 2020 Prix Goncourt, the other one the 2017 Prix de Flore, literature grasps the theme of biofabrication. Biofabrication is an anecdotal reality of our technological society in L’Anomalie, but forces us to rethink the relationship to the body in L’Invention des corps.

Clément Duclos-Vallée, a student at the Ecole Normale Supérieure - Lettres, gives us an account of his reading of these two books in his article "Biofabrication, fabriquer la vie", which can be downloaded here.

Neanderthal-like mini-brain

The issue of Nature dated 11th of February discusses the findings on a “Neanderthal-like mini-brain’ as published by Science on the same day.

Researchers started by altering the genome of human pluripotent stem cells and swapping the human NOVA1 gene for its Neanderthal and Denisovian variant. Then, they cultured the stem cells into cerebral organoids.

These organoids differ from human ones, in size, shape, texture and activity. It may be that humans have benefited from the change of a single base of NOVA1 for yet unknown advantages.

BONE - Bio-fabrication of Orthopaedics in a New Era

Osteoporosis is the leading cause of bone fractures in all regions of the European Union. The economic and societal burden of bone fractures is enormous and could be reduced by implementing affordable and curative healthcare solutions that ensure faster recovery with lower healthcare costs.

The emerging field of regenerative medicine offers potential solutions: 3D scaffolds created through an innovative technology called electrospinning promise to support the regeneration of skeletal bone and replace the need for tissue donors, repeated operations or drugs in progress.

The objective of the BONE research project is to accelerate the valorization of profitable 3D implants manufactured by electrospinning in collaboration between 4 research institutes, 4 business support organizations and 5 industrial organizations.

Medicen Paris Region, founding member of the IFBF, is a partner in this project.

Differentiation of stem cells into hepatocytes: new protocols and clinical applications

A recent article published in the journal Hepatology reports on the progress of protocols for differentiating stem cells into hepatocytes. Human pluripotent stem cells can be amplified indefinitely and differentiated into any type of cell. But the liver cells obtained after differentiation have more foetal characteristics than adult ones. New technologies have been used to improve the differentiation process in recent years. They give hope for promising clinical applications.

The article was written by E. Luce and A. Messina under the supervision of A. Dubart-Kupperschmitt and JC Duclos-Vallée, members of the IFBF and involved in the iLite project.

It will be available soon through this link.

A biomanufacturing campus for regenerative medicine in Canada

The Ontario Institute for Regenerative Medecine (OIRM), founded in 2014 and funded by the Canadian government, brings together more than 250 researchers from the province of Ontario specialized in stem cell culture and biofabrication (skin, heart muscle, etc.) .

Responsible for promoting the results of the research from OIRM, the Center for Commercialization of Regenerative Medicine (CCRM) is a project accelerator specializing in regenerative medicine, cell therapy and gene therapy. Funding is provided by the Canadian government and the Province of Ontario. It has a 40,000 ft² platform located in Toronto, a quarter of which meets the requirements of Good Manufacturing Practices-GMP.

CCRM plans with the innovation park of Hamilton, the third largest city in the province, to build a "biomanufacturing campus" specializing in regenerative medicine around what will be the largest Contract Development and Manufacturing Organization (CDMO) of Canada (see the press release here).

Canada is thus asserting its ambitions in regenerative medicine, bioproduction and biofabrication.

Rethinking innovation in health

Contemporary society attributes significant merits to innovation, especially in the field of health. Medical innovation is supposed to increase lifespan, improve the quality of life and generate significant economic benefits.

This is all the more the case for so-called disruptive innovations, including biofabrication, the results of which are considered a priori to be very promising.

However, experience shows that "there is often only a step between disruption and sensationalism" and a legitimate question is asked: "Does a drug that is effective but inaccessible because too expensive constitute real progress? "

In a recent note, Inserm's Ethics Committee questions innovations in their definition, the means of evaluating them and orienting their production according to their characteristics.

The Committee's note, in French, can be downloaded (here) or viewed on the Inserm website (here).

In addition, the 7th edition of the annual Inserm Ethics Committee meeting, on November 25, will be dedicated to this theme. To register, follow this link.

Formation of bile tubes in a 3D culture system

Researchers from Inserm UMR_S1193 at Paul Brousse Hospital in Villejuif led by Anne Dubart-Kupperschmitt (see here), member of the IFBF Scientific Committee, have shown, as part of the iLite University Hospital Research project ( innovations in Liver tissue engineering), that induced human pluripotent cells (hiPSCs) could be differentiated into cholangiocytes capable of self-assembly to form bile tubes in a three-dimensional culture system. The active transport of a fluorescent bile acid analog has shown the functionality of the tubes formed, demonstrating the potential of these structures in a bioconstruction approach.

The article detailing the protocol appeared last July in Methods in Cell Biology volume 159 (see here).

Organoids: created in vitro but as close as possible to living tissues

The “Quotidien du Médecin” reports in an article published on September 8 (see here) of its interviews with several organoid specialists, in particular Anne Dubart-Kupperschmitt, member of the IFBF Scientific Council (see here) and Jean-Charles Duclos-Vallée, president of the Institute (see here).

Researchers and clinicians have highlighted the great interest that organoids represent for the understanding of diseases (currently Covid-19, see our post of June 26), the development of new molecules, the regeneration of tissues and the transplantation of organs. They also mentioned the challenges they face, that of vascularity in the first place.

Particular emphasis has been placed on liver organoids capable of reproducing large numbers of organ functions, the total of which exceeds 500. The article ends with the mention of the test on small animals of a hepatic bioreactor, one of the objectives of the iLite project (see here).

Tissue engineering and the pandemic

After Nature (see the news dated June 26, 2020), the New York Times echoes the use of tissue engineering, and in particular bioprinting, to test pharmaceutical molecules.

"...Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine, and his team are creating tiny replicas of human organs — some as small as a pinhead — to test drugs to fight Covid-19.

The team is constructing miniature lungs and colons — two organs particularly affected by the coronavirus — then sending them overnight by courier for testing at a biosafety lab at George Mason University in Fairfax, Va...

In the past few years, Dr. Atala’s institute had already printed these tiny clusters of cells to test drug efficacy against bacteria and infectious diseases like the Zika virus, “but we never thought we’d be considering this for a pandemic,” he said. His team has the ability to print “thousands an hour,” he said from his lab in Winston-Salem, N.C."
