REGEMAT 3D Will Start Selling Biomaterials

One of the key players in the bioprinting field in Spain will be incorporating seven new biomaterials. In the coming months, REGEMAT 3D will launch a catalog of biomaterials that customers can buy and use along with their bioprinting systems. According to company officials, in recent years, advances in 3D bioprinting systems have become very important, as well as new biomaterials for regenerative medicine. The performance of the research groups with which they collaborate has produced results that were likely unheard of years ago. Still, they consider that these innovations in bioprinting systems must be accompanied by a progressive definition and characterization of the biomaterials being used. This year, one of REGEMAT 3D’s objective is to advance biomaterials for further research in the different applications derived from the 3D bioprinting sector, which is growing every year.

Each specific application requires different solutions and appropriate biomaterials to optimize processes. For instance, it is easy to understand that to regenerate skin components, hydrogels, cells and growth factors are different from those needed to regenerate muscle tissue, bone or cornea. So, it is essential to offer researchers and scientists different biomaterials to aid their work. REGEMAT is focusing on seven: thermoplastics, collagens, alginates, agaroses, gelatin methacryloyl (GelMA), nanocellulose, and different types of cell media compatible with the cells used. All of the biomaterials should be easy to print, handle and will allow researchers to tackle some of the challenges they face while working. 

The new biomaterials for 3D bioprinting will be available on the company’s web page (which they will relaunch shortly), as well as through their offices. REGEMAT 3D has agreements with several national and international partners for the manufacture of these products. The first ones to be sold commercially will be nanocellulose, collagen, and alginate.

The Granada, Spain-based biotech company has sold its machines to users in more than 25 countries. For years, the company has been working with research groups at the University of Granada in advanced therapies, participated in a joint project for the development of new therapies for cartilage regeneration, and has collaborated with the University Hospital of La Paz, where REGEMAT 3D’s founder coordinates the 3D Tissue Engineering and Printing Platform (PITI3D), which provides ingredients and processes to generate functional tissues. Since its origin, the startup has been focusing on regenerative medicine, developing custom hardware and software required and demanded by some of the major hospitals and research universities in the region. They develop their own bioprinting systems – the BIO V1 machines – and customize them for their users’ applications according to the requirements of each investigation.

Last January, a group of researchers led by the University of Granada and REGEMAT 3D, published an academic article on the development of a volume-by-volume 3D biofabrication process that divides the printed part into different volumes and injects the cells after each volume has been printed, once the temperature of the printed thermoplastic fibers has decreased. This helps overcome problems that arise when working in 3D bioprinting with thermoplastics at high temperatures: one of the biomaterials they will soon begin commercializing, with which the company is very familiar and has worked with for a long time. 

To continue developing new biomaterials and launching new products, the Spanish company, led by founder and CEO José Manuel Baena, has managed to raise 320,000 Euros in the midst of the latest financing round. REGEMAT 3D, along with its sister company Breca, are not only launching the new series of biomaterials, but they are also expanding their presence to Brazil, where the company has already started to market its products, and China, where they closed an agreement with Chinese distributor ApgBio, based in Shanghai, that’s responsible for introducing bioprinting equipment in the country for the regeneration of organs or tissues. Companies like REGEMAT 3D are gearing up to mass produce biomaterials, providing researchers with more options when it comes to bioprinting for regenerative medicine and advanced therapies, usually keeping in mind how patients bodies will react to the new materials, and whether they will be compatible. Spain, like many other European countries, is quickly catching up to the world of bioprinting, which today is led by US-based companies but shows promise in many developed countries.

Interview with Dr. Vahid Serpooshan, Who Created a ‘Heart Attack Patch’ With the Help of 3D Printing

According to the World Health Organization, cardiovascular disease is the number one cause of death globally. An estimated 17.9 million people died from cardiovascular disease in 2016, representing 31% of all global deaths. Treatments for all manner of cardiovascular impairments are therefore a high priority. A very prevalent ailment in that category is a heart attack which happens to over 735,000 Americans a year

A team of researchers led by Dr. Vahid Serpooshan, an assistant professor of Biomedical Engineering and Pediatrics at Georgia Institute of Technology and Emory University School of Medicine, have created a patch with a regenerative protein to treat the infarcted myocardium (cardiac muscle, a part of the heart that gets damaged during a heart attack). According to Georgia Institute of Technology the patch will cover the infarcted tissue with a collagen patch infused with a  protein called FSTL1, which is tailored to fit an area a little larger than the dead tissue. Dr. Serpooshan used bioprinters to develop the patch using a collagen gel. The patch is about to start its pre-clinical trial phase at Emory University’s School of Medicine in Atlanta, and a clinical trial is already ongoing in Europe for a version of this patch device. So it could be a couple more years before they are available for patient treatment. Dr. Serpooshan’s Lab (which has two locations at both Emory University and Georgia Tech) uses a multidisciplinary approach to design and develop micro/nano-scale tissue engineering technologies with the ultimate goal of generating functional tissues and organs. 3DPrint.com reached out to talk to Dr. Serpooshan about his team’s groundbreaking work.

How has 3D printing helped to engineer the patch?

3D printing has been a huge help in manufacturing the patch in so many ways. It enabled us to incorporate vasculature inside the patch, something that would not have been available with traditional tissue engineering techniques, since they offer really limited potential to create complex, functional vasculature in thick, 3D tissue constructs. Additionally, it allowed us to have a controlled deposition of different cells, biomaterials, and molecules to form heterogenous, complex 3D structures that closely mimic native tissue structure. Also it provided us with patient -and disease- specificity: we utilize MR or CT imaging data obtained from patients to create 3D printed tissue constructs that precisely match the patient’s diseased or damaged tissue. Finally, bioprinting technologies have enabled tissue engineers to markedly enhance resolution and precision in various tissue manufacturing endeavors, making precision medicine even more promising.

What 3D printer do you use to create the patch?

We are mainly using two types of 3D bioprinters for this project. A BioAssemblyBot bioprinting system, made by Advanced Solutions Inc. (an American company in Louisville, Kentucky). This is the ONLY six-axis robotic arm printer in the market, with a resolution down to approximately 20 to 50 μm (microns). The second bioprinter is a BIO-X from Swedish biotech company Cellink, a pioneer in bioprinting.

How long will it take to manufacture the patch?

Biomanufacturing of a cardiac patch at a clinically-relevant scale would take about 15 to 30 minutes, depending on the number of cell types involved, the vasculature design, and other factors. This enables the clinics, hopefully in the near future, to have heart attack patients come to the clinic, conduct CT or MR imaging, prepare 3D digital model of the damaged tissue, and sending it to the bioprinter to manufacture a patch device customized for that patient.

Is there already a procedure in place to apply the patch?

Actually, there already is a procedure to apply the patch. We use a left thoracotomy approach to get access to the surface of the heart and suture the patch onto the epicardial layer of the heart, covering the myocardial infarction (also called a heart attack) area. There are currently some ongoing works trying to minimize the aggressiveness of this surgical procedure, potentially using catheter-based techniques.

What are the benefits of using collagen in the patch?

Collagen is the most abundant protein of the human body. This protein highly supports cell viability, proliferation, and function. It is a biodegradable protein which is a major advantage for in vivo applications, facilitating timely integration of the implant with the host tissue and avoiding long-term immunogenic complications. For our 3D bioprinting works, we use gelatin methacrylate (gelMA). Gelatin is derived from collagen (a hydrolyzed collagen) and offers similar advantages. The main advantages of gelMA for bioprinting of cardiac patches include: acceptable compatibility with cardiac cells (cardiomyocytes), tunable biomimetic mechanical properties (stiffness), controllable degradation rate, and of course, great printability (rheology properties).

What percentage of heart disease patients will benefit from this device?

This therapy is designed for a specific group of heart attack patients, approximately one third of patients who either arrive too late to the clinics or are resistant to current catheter-based reperfusion methods and pharmacologic therapies.

If approved, Dr. Serpooshan’s patch could help over 200,000 patients per year.
