Reading a living cell's transcriptome, without destroying it.

Every single-cell RNA-seq method in routine use today starts the same way: the cell is lysed. It's a one-shot, destructive snapshot. GenXMap is building a live single-cell omics method to read transcriptomic state from an intact, living cell, opening the door to real kinetics at single-cell resolution.

The scientific problem

Single-cell transcriptomics has transformed biology, but every established protocol destroys the cell to read it. That means you get one timepoint per cell, ever: no re-sampling, no kinetics, no way to watch the same cell change state and later confirm what it became. For biological questions that unfold over time (a cell responding to a drug, a rare clone drifting toward resistance, an immune cell differentiating) that one-shot limit is the ceiling.

Current approach

Cell isolated → lysed → RNA captured → sequenced. Destructive by design. Every timepoint requires a fresh, separate cell: and population-level inference stands in for true single-cell kinetics.

What GenXMap is building

A method to extract transcriptomic signal from a single living cell without lysis, preserving viability so the same cell can be measured again, tracked, or recovered for downstream use.

Why non-destructive matters

Removing the lysis step doesn't just save a sample. It changes what questions are answerable. Longitudinal single-cell data, paired before/after measurements on the same cell, and downstream functional assays on cells that were previously "read" all become possible for the first time at single-cell resolution.

Direct fallout for oncology

  • Track tumor heterogeneity in the same cell population over time, instead of inferring change across separate biopsies.
  • Observe drug response kinetics without repeated invasive sampling.
  • Follow rare or resistant clones (e.g. emerging drug-resistant subpopulations) as they evolve, not just at a single endpoint.
  • Recover the measured cell for downstream functional or clonal assays, the reading no longer consumes the sample.

Program approach

A multi-year internal research program moving from early feasibility work through validation and, ultimately, integration into GenXMap's platform. We keep programme-stage detail out of the public domain while IP and partnership discussions are ongoing, get in touch for a deeper briefing under NDA.
