A numbers of years ago while doing my masters and deciding upon what to do. I became intrigued by bioprinting. One particular application was cell adhesion and so I set out to create some ecms (extra cellular matrices or scaffolds) and grow some osteoblasts (bone) on the scaffolds.
Having a limited budget I went off and bought a number of 3d printers and started modifying them into #3dbioprinters. However afterwards I was subsequently told that my budget had been cut rather significantly by the university where I was studying. Being not a very happy bunny I decided to print some fingers for my scaffolds, well metacarpals and distal phalanges to be precise.
Mozart has his musical joke and I had my fingers. :-)
