Story summary

Swedish researchers developed two 3D bioprinting techniques to regenerate living skin for severe burns and trauma.
Current methods leave scars and fail to restore skin functionality by not regenerating the dermis.
One technique produces cell-rich skin, while the other forms blood vessels.
The team created a bio-ink, “uInk,” to cultivate fibroblasts for dermal components.
Experiments with mice showed living cells grew inside tissue fragments, rebuilding dermal components and forming new blood vessels.
