Bio-Printed New Skin: More than Skin-Deep

The Bio-Printer and the Bioprinted Skin

Half a world away in Spain, a new bio-printer claims to be able to make new skin. A team of experts at the Carlos III University of Madrid came out with a machine reportedly capable of 3D-printing sheets of functional human skin for use in research or even for transplants. If it breaks through, it can make possible skin grafting using a patient’s own skin obsolete.

The new 3D printer, or aptly bioprinter, uses bio-inks made up of skin cells, plasma, proteins, and other biological components known to exist in human skin, as fibroblasts and keratinocytes. By the principle of additive manufacturing, the computer will selectively and precisely deposit layers of biolinks on the print bed. Critical to the system is how to mix the components under certain conditions and the precise depositing to prevent deterioration of the cells.

The final product produced should consists of what natural skin is – outer layer called the epidermis and the deeper, thicker layer called the dermis, which contains collagen-producing fibroblast.

For purposes of research, as in the field of pharmaceuticals or of cosmetics, the bioprinted skin can be derived from any human skin cells, such as those obtained from skin biopsies . But if it is for therapeutic treatment, as in transplants, burns, and other forms of skin injury, the patient’s own skin cells are required. It takes approximately 2 weeks to grow new skin in the laboratory, and a day or two to print them.

Research facilities in other countries have also manufactured their own bioprinting machines and printed skin derived from patient’s own skin cells. One such facility is based in the University of Toronto and their reports were released in 2014.

These results demonstrate that 3D bioprinting is a suitable technology to generate bioengineered skin for therapeutical and industrial applications in an automatized manner.

3D Printed Bone Grafts

3D-Printed Bone Grafts: The Future of Fracture

3D Printing Mimics Real Bone

The University of British Columbia (UBC) Okanagan, Department of Engineering, through the efforts of a brilliant research assistant, Hossein Montazerian, is modeling and creating artificial bone grafts via 3D printing. He hopes that where artificial bone replacements are concerned, 3D printed grafts will answer the unmet needs of complex bone grafting in surgery.

While human bone is resilient, injured or fractured bone will need replacement, sometimes multiple surgeries and painful recoveries. To replace a fracture, surgeons may have to take a patient’s normal bone and transfer it to the injured part using conventional bone grafts. By using the patient’s own bone fragments, they mix and integrate well with the patient’s fractured bone and associated connective tissue.

Montazerian’s new design for artificial bones ensures that 3D printed bone parts have the same unique porosity of bone, the same permeability and elasticity. Although artificial, the parts are made stronger, safer and functionally effective. This means that parts can be customized to fit a patient’s particular situation, the surgeon will not need to transplant bone, effectively decreasing operation time and is less traumatic for the patient.

Montazerian analyzed 240 different bone graft designs, 3D printing the top performing ones using the powder-based method of printing. He also utilized numerical procedures to determine the best pore characteristics for normal bone stiffness, strength, and permeability.

The grafts were made of calcium sulfate scaffolds using TPMS-based unit cells, or Triply Periodic Minimal Surfaces that are present in natural shapes and structures. He focused on those that make strong and porous bones and subject them to mechanical and compression tests.

The aim of this type of regenerative medicine is to replace missing or damaged bone tissue with 3D printed synthetic grafts with their interconnected scaffolds to allow adhesion, growth, and proliferation of the human bone cells. Montazerian said that the ultimate goal is to produce a replacement that almost perfectly mimics real bone.

Revolutionizing Cardiology via 3D Printing in Seattle

The Heart of the Matter

A biomedical engineer, stem cell engineers, clinical cardiologists, and some 3D printing experts came together to successfully come up with a high-tech solution that could revolutionize cardiology.

Bear in mind that as hundreds of thousands of Americans suffer or die from myocardial infarction, doctors continue to resort to modern advances in pharmaceuticals and technology to find better cures for MI and other life-threatening cardiac conditions. The problem, really, is that heart muscle damaged by a cardiac event will develop scar tissue at the site, reducing heart function to a significant degree.

This is not about specific medications, or catheters or stents or other known interventions that can improve survival rates or save a patient’s life. With the exception of a heart transplant, there may not be any other long-term solution to damaged heart muscle. So comes in our team of researchers aiming to mend broken hearts by means of a special 3D printed scaffold – a stem cell-derived cardiac muscle patch.

From the University of Minnesota-Twin Cities, the team used stem cells derived cardiac muscle and actually mixed those with other cell types needed for blood vessels. This will block the formation of fibroblasts, which produce the scar tissue. They created the patch, a biocomplex of printed layers, and tried it on cardiac arrest-induced mice. This was a comparative study using 2 groups of rodents, half were given the cell mix patch and the other half, cell-free patches.

Significant improvements were seen in the functional capacity of the rodent hearts with crell mix patches after just four weeks. It showed marked reduction in adverse remodeling of damaged heart tissue and preservation of cardiac performance. Measurements of cardiac function, infarct size, apoptosis (or cell death), both vascular and arteriole density, and cell proliferation at week 4 after treatment were significantly better. Continuous electric signal generated across the patch, and then paced, increased the frequency of the heart beats.

This in effect strengthens heart muscle allowing better circulation and more efficient distribution of nutrients to the injured heart areas. By and large the research outcomes looked very promising though more studies are needed to be conclusive about this direction.
