3D printing has proved to be a significant breakthrough technology in various industries, including the medical industry. How can it contribute to the enhancement of treatments in the medical industry?
FREMONT, CA: In the past few years, various additive manufacturing techniques (3D printing) have been utilized for producing scaffolds with controlled micro-architecture and geometry. Techniques utilizing 3D printing have displayed massive potential as a substitute film-forming approach for numerous applications, including wound healing enhancement. 3D printing of human-made scaffolds supposed to replace wounded tissues has turned out to become a ballyhooed technology that’s yet to demonstrate itself in clinical practice. One factor that makes things more complex is that the scaffolds need to match the volume that they will be replacing, in shape, as well as the direction in which cells are required to develop. In order to do this, it was vital to create 3D models of the area to be diagnosed, and they have to be instantly matching the autonomy of every patient.
Leaving behind all this, researchers at the University of Connecticut have come up with a bioprinter that is capable of depositing a biocompatible fibrous scaffold straightforwardly where it is supposed to remain. The technology is specifically advantageous for addressing volumetric muscle loss for which there is not much availability of good options these days.
This approach does not need any suturing for depositing the printable gel that does the job of the matrix, in which new cells are able to proliferate and grow. The gel is typically adhesive to wound tissue and remains stuck where it is placed. Because of the fact that the approach does not need modeling and printing of the scaffold outside the patient, it might enable for very rapid deposition and quick treatment of acute wounds.
Until now, the new gel and bioprinter combo have been tried in mice having volumetric muscle loss injuries, and the material adhered to the close by tissues and helped in speeding up the skeletal muscle growth.
