In 2021, a research team in the United States developed the first living robot made entirely of animal cells, rather than metal. This robot, grown from cultured frog cells, not only moved independently but also reproduced. However, the scientific community at the time disputed the robot's self-reproducing ability, arguing that it was due to its amphibian nature. This time, the research team succeeded in creating a living robot using human cells instead of frog cells. The robot was created using somatic cells with cilia, hair-like projections. [Gizem Gumusskaya / Researcher, Department of Biology, Tufts University: Anthrobot is the first living, living robot made entirely of human cells. It possesses the unique ability to function as a machine using living biological cells, without electrical wiring or mechanical components.] Multiple cells were arranged in a specific structure, and each cell used cilia to move as if swimming, forming a single robot. These biorobots range in size from 30 to 500 micrometers and have various shapes. Specifically, when placed on a sample of human nerve cells, this robot moved across the surface and repaired the gaps in the cell layer over three days. [Michael Levin / Professor of Biology, Tufts University: In the future, we can extract individual cells from a patient and precisely design them to exhibit the desired shape and movement. These can then be injected back into the patient's body to perform therapeutic functions.] Biorobots can be created solely through cell culture, so there's no risk of immune response or genetic mutation when introduced into the body. Furthermore, they are safe, naturally degrading within the body after a few weeks. The research team anticipates that further elucidation of the principles of biorobots could lead to their use in treating injuries to the spinal cord, retinal nerves, and other areas. These research results were published in the international journal Advanced Science. YTN Science, Lee Dong-eun.
