UK researchers have used inkjet printing technology to successfully use ganglion cells and glial cells taken from the eye as “ink” in printing retinal patterns.
The breakthrough could lead to the production of artificial tissue grafts made from the variety of cells found in the human retina and may aid in the search to cure blindness.
The results are preliminary and provide proof-of-principle that an inkjet printer can be used to print the two types of intact cells from the retina of adult rats in patterns.
The ability to arrange cells into highly defined patterns and structures has recently elevated the use of 3D printing in the biomedical sciences to create cell-based structures for use in regenerative medicine.
Yup, the printing of organs with peoples own stem cells is becoming a reality. This is so totally cool ... and makes me think, again, of the things we could do if we directed our resources towards things that improve life and knowledge rather than ending them.
A trite, old thought... but really, imagine the rapidity of advances if a third of the defense budget were allocated to cutting edge sciences.
