Stem Cell Fate & Lineage Tracking Reporters
LineageBeacon™ secreted reporters for real-time monitoring of pluripotency, differentiation, and developmental signaling.
Non-destructive monitoring of stem-cell differentiation
Targeting Systems has developed a proprietary panel of secreted stem-cell lineage-tracking reporter systems designed to monitor pluripotency loss and lineage commitment in real time.
Unlike conventional endpoint assays that require cell lysis, fixation, or destructive sampling, secreted reporter technologies enable repeated monitoring from culture supernatants while preserving the same cell population for continued differentiation, imaging, or downstream validation.
Key Differentiator
Secreted reporter technologies enable repeated, non-destructive monitoring of stem-cell differentiation from the same culture over time without cell lysis, fixation, or endpoint sampling.
Stem Cell Fate & Lineage Tracking Reporters Roadmap
Secreted lentiviral reporters for non-destructive monitoring of stem-cell differentiation.
Conceptual progression: iPSC / stem cell state → OCT4 → TBXT → branching into TNNT2 cardiac and PECAM1 endothelial differentiation, with SFHP providing a hypoxia/developmental-signaling readout.
Compact product panel
The LineageBeacon™ Reporter Panel includes:
Available formats:
- Prepackaged lentiviral reporter panel for evaluation and stable reporter cell-line generation
- Sequence-verified lentiplasmids available upon request or for custom projects
- Custom reporter configurations, including dual-modality or far-red fluorescent fusion options, can be discussed for sponsored development projects
