New York Researchers Create New Hair With 3-D Printer


In a groundbreaking achievement, researchers at the Rensselaer Polytechnic Institute of New York have successfully employed 3D printing to create hair follicles within lab-grown human skin tissue. This landmark development, documented in the journal Science Advances, not only holds promise for addressing the cosmetic concern of baldness but also represents a significant stride forward in the realm of regenerative medicine.

The integration of hair follicles into engineered skin tissues provides a more realistic platform for researchers to explore how the skin interacts with various formulations. Beyond its aesthetic implications, this breakthrough showcases potential applications in testing more effective treatments for a diverse range of skin conditions.

The implications of this achievement extend beyond aesthetics, hinting at possibilities for automating biomanufacturing processes in skin production. The 3D cultivation of human-derived cells shows promise not only in generating new hair follicles and shafts but also in advancing successful skin grafts.

The research involved specialized 3D printing techniques at the cellular level. Skin and follicle cells were cultivated until a sufficient quantity of printable cells was obtained. These cells were then combined with proteins and other materials to formulate a unique “bio-ink” for the printer. Utilizing an ultra-thin needle, the printer deposited the bio-ink layer by layer, creating channels for the placement of hair cells. Over time, skin cells migrated to these channels, mirroring the natural follicle structures found in authentic skin.

This groundbreaking achievement marks a significant leap forward in the field of skin tissue engineering. The successful 3D printing of hair follicles opens up possibilities for the future development of 3D-printed skin grafts capable of growing hair. The scientific community anticipates transformative impacts on medical procedures related to artificial hair transplants, paving the way for innovative approaches in regenerative medicine.
