That scan is used to 3D-print a hollow, permeable, life-size model of the part. ... (which provides skin with its structure), and keratinocyte cells (which make up the outer layer of the skin).

At this point, the tissue mimics the three-layer structure and biomechanics of human skin. The scientists note that they're now ready to use their first batch of skin models in nanoparticle testing.

With continued progress, these synthetic structures may soon serve as the gold standard in testing safety and toxicity of substances applied to human skin. In conclusion, the development of 3D ...

Rensselaer Polytechnic Institute scientists have 3D-printed hair strands in lab-grown human skin tissue. They have made a significant step forward for skin engineering and opened new possibilities ...

The first skin models are now ready for nanoparticle testing. Hydrogels in which skin cells survive and grow “The hydrogels for our skin imitation from the 3D printer have to fulfil a number of ...

These structures, called dermal denticles, are more like teeth than skin. Made of dentin and enamel, they are innervated, and their ribbed and layered pattern guides water across the shark’s ...
