Biotechnologist and pioneer in bioprinting with living cellsJemma Redmond, who has died aged 38, founded the Irish 3D bioprinting startup Ourobotics, and developed the first 10-material bioprinter capable of using live human cells. Bioprinting – the use of 3D printing, with largely organic materials – is creating organs for surgeons to use in patients. Today, surgery using bioprinted body parts is in its first trials.In February 2016, the neurosurgeon Ralph Mobbs in Australia placed two 3D-printed cervical vertebrae, made of titanium, in the upper neck of a patient whose cancer tumour was slowly compressing his brain stem and spinal cord. It was a world first, and a rarely attempted surgery, largely because of the difficulty in making a fit with bone from elsewhere in the body. But much more can be done by printing with actual cells, instead of titanium. The next step – printing surgically usable kidneys, livers and hearts – requires advances in two areas, bioprinting and stem-cell technology, allowing printing to use a person’s own cells.
