Stem cells can offer new hope as a treatment for several serious diseases, including arthritis, diabetic complications, several cancers, liver diseases and more. Today, the production of stem cells is a complex, highly-skilled, and labour-intensive task, with a high risk of contamination or human error. Therefore, the EU funded Horizon 2020 research project “Autostem”, led by the National University of Ireland Galway (NUIG), has been working on a fully automated production line for stem cells.
At their final meeting at the Fraunhofer Institute for Production Technology IPT in Aachen, Germany, the ten international project partners from four European countries presented a whole new production platform demonstrator which was built in the three-year project for the generation of therapeutic cells at the litre scale.
The Autostem platform concept has been designed as a user-oriented, closed, automated system to provide an efficient pipeline for the delivery of large numbers of therapeutic cells (mesenchymal stromal cells or MSCs). The process starts with a bone marrow donation, taken from the hip bone of a donor using a novel suction device developed to improve the patients’ comfort and yield.
The bone marrow can be transferred in a sterile manner into the Autostem production line, where a robotic arm supports the isolation of MSCs from the bone marrow. The production line also includes capacity for real-time process management, monitoring of cell quality and environment and maintenance of the bio-reactor.
Flexible, automated cell production platform with related software and fully integrated functional modules
This entire process involves no hands-on human operations. While the system is of course monitored by scientific staff, the cell production process is entirely automated. This removes much of the risk of error or contamination, so that the pipleline will generate large amounts of high-quality cells, suitable for use in therapy.
In addition to the novel pipeline itself, other innovations include tailored sensors that provide real-time in-process monitoring during production. Commercially available sensors track dissolved oxygen, pH and temperature, but the Autostem team have developed additional sensors to also track glucose, lactate and ammonia.
The platform represents a fully equipped, automated laboratory which will soon be working in a completely environmentally controlled area and is capable of isolating and expanding MSCs autonomously in a full end-to-end, adaptive process. Its modular and highly integrated design combines state-of-the-art laboratory equipment with novel technological developments:
The pipeline allows for close monitoring and control of production and environmental parameters and paves the way towards sophisticated production schemes that are adaptive to cell behaviour. In this way the Autostem platform has been built to deliver a significant advance towards the routine clinical application of cell therapies in the future.
Exploring commercial perspectives of the project outputs
The Autostem team which has been working together in the project represents a wealth of experience in regenerative medicine, automation and robotics, bio-reactors and cell production, regulatory affairs and quality control, over more than ten years.
The project began on 1 January 2016 and finished successfully on 31 December 2018. Finally, the researchers have been biologically validating the cells that had been produced in the project in vitro and in vivo, in order to ensure the clinical-relevance of the product.
As the prototype of the Autostem platform has been finished now, more work will be needed to allow for direct clinical use in patients, so the next steps will be exploring the markets for the project outputs. New knowledge about MSC selection and expansion, bioreactor systems, sensor technology and MSC action has been gained, which will present opportunities for further research and collaboration.
“The project is paving the way towards the cost-effective manufacture of MSCs and other therapeutic cell products in the future. Ultimately, this will benefit patients, clinicians and health systems, yielding wider societal and economic benefits”, says Dr. Mary Murphy of the National University of Ireland, Galway, Coordinator of the Autostem project.

New method for the measurement of nano-structured light fields

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails.
Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in...

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
