Researchers Employed An Improved 3-D Printer To Create Human Cells and Artificial Tumors

In recent years, the focus of medicine has started to shift from a general one-for-all solution to personalized treatments which are specifically tailored for each patient. A team of researchers has managed to create a new type of 3-D printer which can build human cells and artificial tumors. These tumors can be used by other researchers to study and evaluate the potential of experimental drugs and therapies without risking the lives of actual patients.

At this point, the research related to human health is quite expensive. In most cases, research which seeks to combat particular disease will take place in a laboratory.

The scientists will employ a model of an animal or human cells which consists of a single layer. This layer will be exposed to potential treatment methods, and the researchers will evaluate the changes which take place at a cellular level.

Using a 3-D printer to produce human cells and artificial tumors might be helpful in research

Many researchers believe that the use of 3-D printer models would be more effective in the long run since the additional layers of cells can imitate the same conditions which are found in the body. Another benefit would be the elimination of tests which involve the use of live animals. The new printing method uses high-power magnets which can print 3-D clusters efficiently.

The team spent a long time on the study of magnetic properties featured by different materials. They discovered that some of the materials feature a high magnetic susceptibility which allows them to be easily attracted by a magnet while materials which aren’t influenced by the magnets will tend to remain at the lower regions of the magnetic field.

This information was harnessed in the form of particular magnetic fields created by finely-tuned magnets. Bioinks were created by placing human breast cancer cells in a unique cell culture medium which contained a high amount of magnetic salt hydrate. By using this knowledge, the researchers were able to use a 3-D printer to print tumors in six hours. Further tests have shown that artificial tumors are suitable for medical research.
