RBCC Partner N3D Could Revolutionize Toxicity Testing

  RBCC Partner N3D Could Revolutionize Toxicity Testing

Business Wire

NOKOMIS, Fla. -- January 30, 2013

New research indicates that 3-D cell culturing technology developed by Rainbow
Coral Corp. (OTCBB: RBCC) partner Nano 3D BioSciences (n3D) could make
toxicity tests for airborne chemicals faster and more effective than ever

In collaboration with scientists at Rice University, Dr. Glauco Souza of n3D
led a research study that demonstrates the potential of the company’s magnetic
levitation tech to grow some of the most realistic lung tissue produced in a
laboratory. In the study, researchers combined four types of human cells to
replicate three-dimensional tissues from the wall of the bronchiole, found
deep inside the lung.

Using traditional 2-D cell cultures, producing cells at the air-liquid
interface, ideal for toxicity testing, is enormously difficult. Using n3D
technology, however, researchers were able to magnetically levitate bronchiole
tissue to the air-liquid interface so that airborne toxins can be exposed to
the epithelial layer of the tissue, just as would occur in human lungs.

The same methods have also been used to culture heart valve tissue. RBCC
believes that its joint venture partner’s technology is on the cusp of
becoming standard equipment in cellular research labs around the globe.

“Scientists everywhere are discovering that n3D’s Bio-Assembler technology can
produce superior cell cultures for a broad range of research fields,” said
RBCC CEO Patrick Brown. “As more and more high-profile cell researchers
discover this system’s potential, the market for the technology will continue
to grow exponentially.”

The Bio-Assembler’s fusion of magnetic levitation and nanoparticle assembly
technology allows it to produce accurate, 3D representations ofin
vivotissues faster and easier than any other existing tools. The incredible
device is key to RBCC’s plans to participate in the impressive upside in store
for n3D.

“Previously, when I worked at Baylor College of Medicine, we used transwells
to study human bronchial epithelial cells,” said n3D scientist Jacob Gage, who
co-authored the bronchiole study. “After switching to the Bio-Assembler, we
were able to culture multiple cell types to generate an in vivo-like
environment. This gave us the opportunity to create truly three-dimensional
and histologically accurate structures.”
