North Carolina-based medical 3D printing startup Section has secured a $1.8 million grant from the Nationwide Institutes of Well being (NIH) to advance its work in 3D printing expertise for microfluidic organ-on-a-chip fashions.
The first focus of this grant is the event of a blood-brain-barrier mannequin that precisely replicates the in vivo surroundings, aiming to handle present limitations in treating neurological illnesses and mind most cancers. Partnering with Harvard Medical College’s Massachusetts Common Hospital, Georgia Tech, and Virginia Tech, the two-year grant from the NIH’s Nationwide Middle for Advancing Translational Sciences goals to develop and check 3D printing expertise for microfluidics for biomanufacturing and creating organ-on-a-chip fashions.
“With the assist of the NIH and with this group of main researchers, we imagine this venture is not going to solely assist create a greater blood-brain-barrier mannequin, but in addition lay the inspiration for creating different organ-on-a-chip fashions that may drastically profit researchers and sufferers alike,” stated Jeff Schultz, Ph.D., MBA, and Co-Founding father of Section.

Replicating human physiology on a chip
Using 3D printing, Section fabricates microfluidic fashions utilizing biocompatible supplies reminiscent of PDMS, reaching a decision commensurate with organic scales. This expertise allows the incorporation of valves, sensors, and electrodes all through the printing course of, streamlining manufacturing with automation and reproducibility. The venture’s significance is underscored by the rising regulatory concentrate on alternate options to animal testing in each the US and the European Union.
Key researchers from collaborating establishments embody Seemantini Nadkarni, an affiliate professor at Harvard Medical College and Massachusetts Common Hospital. Nadkarni is main the event of a system to check PDMS kinetics throughout organ-on-a-chip system creation. Rafael Davalos, a professor of biomedical engineering at Georgia Tech, is overseeing purposeful testing of the blood-brain-barrier mannequin. Moreover, Amrinder Nain, a professor of mechanical engineering at Virginia Tech, is answerable for fabricating ultra-thin and nanoporous membrane mimics for the mannequin.
The NIH grant builds upon earlier investments and assist from governmental and biotech establishments, together with the Section I SBIR grant, NC Biotech Small Enterprise Analysis Mortgage, One North Carolina Small Enterprise Program grant, participation within the WheelsUP program, and an NIH TABA award to establish market alternatives. These initiatives collectively purpose to assist innovation and development inside the life science sector.

Organ-on-a-chip fashions: the following arrow within the quiver of the healthcare sector
Developments concerning organ-on-a-chip fashions and microfluidics are rising as essential instruments in drug growth and toxicity testing. Simply final month, researchers from Université de Montreal‘s Centre de recherche Azrieli du CHU Sainte-Justine developed a bioink for 3D printing “coronary heart on a chip” gadgets. Utilizing automated 3D bioprinting, the group produced ring-shaped cardiac gadgets with diversified cell varieties.
In line with the researchers, the fashions promise a greater understanding of coronary heart illnesses and drug growth. Combining GelMA, AlgMA, and rGO, this bioink was optimized for cardiac tissue engineering, a primary for AlgMA. It helps cell viability and performance, essential for mimicking actual coronary heart conduct. The group goals for personalised remedy by printing patient-specific coronary heart fashions.
On one other observe, 5 Belgian corporations and analysis facilities have joined forces for the AstroCardia venture, aiming to fabricate a man-made coronary heart and circulatory system for area exploration. This initiative plans to deploy a heart-on-a-chip mannequin aboard the Worldwide House Station (ISS) by 2025. The venture goals to analyze the accelerated ageing processes of the human coronary heart within the distinctive surroundings of area. By leveraging residing stem cells and specialised bioink, researchers hope to duplicate human coronary heart tissue precisely.
