Laser assisted bioprinting of engineered tissue with high cell density and microscale organization.

Over this decade, cell printing strategy has emerged as one of the promising approaches to organize cells in two and three dimensional engineered tissues. High resolution and high speed organization of cells are some of the key requirements for the successful fabrication of cell-containing two or three dimensional constructs. So far, none of the available cell printing technologies has shown an ability to concomitantly print cells at a cell-level resolution and at a kHz range speed.

Laser-assisted cell printing: principle, physical parameters versus cell fate and perspectives in tissue engineering.

We describe the physical parameters involved in laser-assisted cell printing and present evidence that this technology is coming of age. Finally we discuss how this high-throughput, high-resolution technique may help in reproducing local cell microenvironments, and thereby create functional tissue-engineered 3D constructs.
