Magnetic carbon nanotube labelling for haematopoietic stem/progenitor cell tracking
Bibliographic record
Abstract
Haematopoietic stem and progenitor cell (HSPC) research has significantly contributed to the understanding and harnessing of haematopoiesis for regenerative medicine. However, the methodology for real-time tracking HSPC in vivo is still lacking, which seriously restricts the progress of research. Recently, magnetic carbon nanotubes (mCNT) have generated great excitement because they have been successfully used as vehicles to deliver a lot of biomolecules into various cells. There is, however, no report about mCNT being used for tracking HSPC. In this paper, we investigated the uptake efficiency of fluorescein-isothiocyanate-labelled mCNT (FITC-mCNT) into HSPC and their effect on the cytotoxicity and differentiation of HSPC. We found that cellular uptake of FITC-mCNT was concentration-and time-dependent. The uptake of FITC-mCNT into HSPC reached up to 100% with the highest mean fluorescence (MF). More importantly, efficient FITC-mCNT uptake has no adverse effect on the cell viability, cytotoxicity and differentiation of HSPC as confirmed by colony-forming unit assay (CFU). In conclusion, the results reported here suggest the further tailoring of mCNT for their use in HSPC labelling/tracking in vivo or gene delivery into HSPC.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
