Genetically Encoded Circuit for Remote Regulation of Cell Migration by Magnetic Fields
Bibliographic record
Abstract
Magnetoreception can be generally defined as the ability to transduce the effects of a magnetic field into a cellular response. Magnetic stimulation at the cellular level is particularly attractive due to its ability for deep penetration and minimal invasiveness, allowing remote regulation of engineered biological processes. Previously, a magnetic-responsive genetic circuit was engineered using the transient receptor potential vanilloid 1 (TRPV1) and the iron containing ferritin protein ( i.e., the TF circuit). In this study, we combined the TF circuit with a Ca 2+ activated RhoA protein (CaRQ) to allow a magnetic field to remotely regulate cell migration. Cells expressing the TF circuit and CaRQ exhibited consistent dynamic protrusions, leading to migration along a porous membrane, directed spreading in response to a magnetic field gradient, as well as wound healing. This work offers a compelling interface for programmable electrical devices to control the migration of living systems for potential applications in cell-based therapy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
