Neurobots Emerge: Frog Cell Robots with Nervous Systems!
Scientists create biobots with self-organizing nervous systems.
Top Summary
- What happened: Scientists led by Michael Levin created 'neurobots' by integrating neuronal precursor cells into biobots made from frog embryonic cells.
- Why it matters: This breakthrough endows biobots with nervous systems, potentially leading to new behaviors and capabilities.
- What changes for people: Could pave the way for biobots made from patient's own cells to repair tissue damage and deliver targeted drugs in the future.
- Who is affected: This research impacts the fields of regenerative medicine, bioengineering, and evolutionary biology.
Biobots Evolve: From Xenobots to Neurobots
Biobots, starting with xenobots, are tiny, self-powered robots made from frog embryonic cells.
Developed by Michael Levin, Ph.D., at the Wyss Institute and Tufts University, these biobots exhibit remarkable motility.
Previous research highlighted their ability for kinematic self-replication and response to sound stimuli.
Anthrobots: Human Cell Potential
Using human cells, scientists have also created anthrobots.
These anthrobots demonstrated the ability to heal neural wounds in vitro.
This has inspired a vision of using biobots, made from a patient’s own cells, for tasks like spinal cord repair and targeted drug delivery.
The Significance of Novel Lifeforms
Levin states that these novel beings, despite their unmodified genome, reveal aspects of multicellular plasticity.
"Such novel beings, exhibiting both new morphology and behavior, despite their wild-type unmodified genome, can reveal important aspects of multicellular plasticity, of relevance to evolutionary biology, bioengineering, and regenerative medicine."
This helps researchers explore questions like the origin of anatomical properties and the range of forms a genome can facilitate.
Neurobots: A Nervous System Integration
The latest advancement involves creating neurobots – biobots with integrated nervous systems.
Researchers used micro-surgery to integrate neuronal precursor cells into the biobots.
The research, published in Advanced Science, demonstrates that novel nervous systems can self-organize within these neurobots.
How Neurobots Function
Neuronal processes extend between neurons and towards non-neuronal cells on the bots.
Target cells include:
- Multiciliated cells (MCCs) for motility
- Mucus-secreting goblet cells for ciliary beating
- Ionocytes for ion balance
- Small secretory cells (SSCs) that produce MCC-stimulating molecules
What to Watch Next
Future research will likely focus on understanding how the integrated nervous systems control biobot behavior and exploring the potential applications of neurobots in regenerative medicine. Further investigation into using patient-derived cells for biobot creation is also expected to accelerate.
