In the world of biomedical science, an extraordinary discovery is redefining the boundaries between organic and mechanical. The biologists of Tufts University have created 'robotic' entities from human cells, renamed 'anthrobots (I'll link the search here)'. These multicellular structures are not only able to move autonomously in a liquid thanks to cilia made of proteins, but they have also demonstrated a surprising ability: that of promoting wound healing in other human tissues. This innovation opens a new chapter in the use of biotechnology for advanced, potentially game-changing medical applications.
The genesis of the anthrobots
Anthrobots were developed by biologist Michael Levin and his team. These organoids, made up of human cells (obtained from the trachea), self-assemble into multicellular structures. Their movement is made possible by the presence of special protein cilia, which sway and push the structures through the fluid. The coordinated movement ability of the eyelashes is fundamental for their mobility. Cells taken from adult human lung tissue naturally have “cilia” for mucus transport.
The basic concept is not new: in 2020, Levin had already successfully experimented with creating “xenobots” using frog cells. We talked about it in this article. Today, the use of human cells in the anthrobot represents a significant leap in terms of medical and biotechnological applications.
Potential in regenerative medicine
What distinguishes the anthrobots from other similar experiments is their apparent ability to induce healing in other tissues over the course of their two-month “life” (so far the longest duration achieved). During tests, when these organoids were placed on layers of damaged human neuronal cells, a regenerative effect was observed. This “healing” capacity opens the way to new methodologies in the treatment of wounds and tissue regeneration.
The production of these organoids, however, was not limited only to the assembly of human cells. The team had to "lend a hand" with the addition of Matrigel, a protein gel that acted as a "glue" between the cells without damaging the structures themselves.
A change of perspective
Michael Levin argues that these cell clusters should be considered entities in their own right, with specific shapes and behaviors. Instead of seeing them simply as tissues to be studied, anthrobots can be used as biorobotics platforms, systematically modifying their characteristics to achieve useful behaviors, such as repairing damaged tissue. Anthrobots reveal the great versatility of human cells, showing that they can build not only tissues and organs of our body, but also completely different structures that nature itself has never generated. This plasticity in cells and tissues to develop different types of structures opens new perspectives in biomedical research and regenerative medicine.
Controversies and the future
Not everyone in the scientific community is convinced of the value of these discoveries. Some researchers, like Jamie Davies of the University of Edinburgh, remain skeptical about the definition of these aggregates as “robots”. However, the undeniable biological functionality demonstrated by anthrobots, particularly in their effect on damaged neuronal tissues, suggests still unexplored potential.
In summary, anthrobots represent an exceptional example of how the frontiers of biology, technology and medicine are overlapping in increasingly innovative and surprising ways. If their healing and regenerative capabilities are confirmed and further developed, we could witness a true revolution in wound care and tissue regeneration, opening up new horizons in the medicine of the future.
