3D-printed skin closes wounds and contains hair follicle precursors

3D printing in Penn State Lab

By Ashley WennersHerron

Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. The advancement could have implications for reconstructive facial surgery and even hair growth treatments for humans.

Penn State researchers use ultrasound to control orientation of small particles

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape — for example, bacteria from other cells — for years, the ability to control their movement has remained a largely unsolved problem, until now. Using ultrasound technology and a nozzle, Penn State researchers have separated, controlled and ejected different particles based on their shape and various properties.  

Researchers 3D bioprint breast cancer tumors, treat them in groundbreaking study

Bioprinting Breast Cancer Tumor

By Adrienne Berard

Researchers at Penn State have successfully 3D bioprinted breast cancer tumors and treated them in a breakthrough study to better understand the disease that is one of the leading causes of mortality worldwide.

A scientific first, the achievement lays the foundation for precision fabrication of tumor models. The advancement will enable future study and development of anti-cancer therapies without the use of "in vivo" — or "in animal" — experimentation.
