Researchers from Wake Forest Institute for Regenerative Medicine in North Carolina, have developed a portable skin printing system that uses living cells to create tissue-engineered skin grafts to cover burn wounds. It is hoped to be eventually purposed to allow on-site in situ repair of battlefield burn wounds.
The device prints layers of fibroblasts and keratinocytes directly onto the skin. The suspensions with cells are mixed with fibrinogen, type I collagen and thrombin at the moment of application.
The printer was tested on artificially created full-thickness skin wounds in nude mice. The printed cells survived the in situ printing process and wound recovery was much faster than in the control group. The results were presented recently at the American College of Surgeons Clinical Congress.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
