The main goal of this work was to print living cells with an open-source printer, part of the new logic of personalized regenerative medicine.

The presented study provides skin equivalent 3D printing proof of concept with strong indicators such as viable cells integration and generation of a 3D network of neo-secretion ECM (Extra-Cellular Matrix), making the printed skin equivalents as close as possible to the real human skin.

It was thus proved that printed cells survived and growth following the printing process thanks to the developed bio-ink.

Skin equivalents were successfully printed and behave similarly to human skin.

These results are really encouraging with high potential applications in the field of regenerative medicine and 3D organ model systems.
