description: Use to lock the single narrative arc before drafting — converts a set of correct results into one Cell-shaped story that runs hypothesis → mechanism → significance, not a list of experiments.

# Single-Narrative Framing (cell-framing)

## When to trigger

- The science is solid but the manuscript reads like three loosely related sub-projects.
- The introduction opens with paragraphs of background before any contribution.
- Reviewers/colleagues say "what's the one thing this paper shows?"
- You can list the results but not the single story they tell.

## Cell tells ONE story

A Cell Article is a single argument with a beginning, middle, and end:

> **Hypothesis / question → the mechanism we uncovered → why it matters broadly.**

Every figure is a chapter that advances this one arc. If a result does not serve the central story, it belongs in supplement or a different paper. Force the whole paper into one sentence:

> "We show that **[surprising mechanism]**, which explains **[phenomenon]** and means **[broad consequence]**."

If you cannot fill all three brackets without jargon, the framing is not ready — and possibly the story is not complete (`cell-fit`).

## The "complete story" expectation

Cell readers expect the arc to feel **airtight**: each claim is set up, tested with converging evidence, and alternatives are excluded before you move on. Map your figures to the arc:

1. **Fig. 1** — establish the phenomenon / set up the hypothesis.
2. **Figs. 2–3** — identify the mechanism (the molecular/cellular cause).
3. **Figs. 4–5** — perturb it both ways (loss + gain of function) to prove causality.
4. **Fig. 6+** — generality / in vivo relevance / the broad implication.

If a chapter is missing, the reviewers will ask for it — better to see the gap now.

## Cell introduction shape (≈3–4 short paragraphs)

1. **The broad problem** — what the field cannot yet explain, framed for a general life-scientist.
2. **The specific gap / hypothesis** — what is unknown and the question you pose.
3. **Why now / why tractable** — the tool, system, or idea that finally lets you answer it.
4. **What we found** — the advance in plain terms, ending on the broad implication. The reader knows your mechanism before Results.

## The "why now" hooks

Name explicitly which applies:

- [ ] A new tool/system (CRISPR screen, cryo-EM, single-cell, organoid) made the mechanism testable.
- [ ] A longstanding paradox in the field is now resolvable.
- [ ] A clinically/biologically urgent problem makes the mechanism timely.
- [ ] A prediction from a model is now directly testable.

## Title discipline

- **Declarative and specific**: "Protein X drives Y by mechanism Z" beats "Insights into Y."
- The noun phrase carries the mechanism, not just the system.
- Avoid "Towards", "A study of", "Characterization of", "Novel".
- Cell titles are short and often name the molecular actor and the effect.

## Narrative anti-frames (rewrite these)

| Anti-frame                                   | Reframe                                                |
|----------------------------------------------|--------------------------------------------------------|
| "We characterized protein X."                | "Protein X gates process Y — a previously unknown control point." |
| "Here we report several findings on…"        | "We define the mechanism by which… "                   |
| Three parallel mini-stories                  | One arc; demote side-results to supplement             |
| "Our data are consistent with model M."      | "Our perturbations decide between models, favoring M." |

## Output format

```
【One-sentence story】 "We show that ... which explains ... and means ..."
【Figure-to-arc map】 phenomenon / mechanism / causality (LOF+GOF) / generality
【Why-now hook】 which applies
【Intro skeleton】 problem / gap / why-now / advance+implication
【Working title】 declarative, names the actor + effect
【Risk】 any chapter of the arc missing? (→ cell-fit)
【Next】 cell-writing
```

## Anti-patterns

- **Do not** present parallel mini-stories — Cell wants one arc.
- **Do not** bury the advance below background; the mechanism belongs in the first paragraphs.
- **Do not** inflate with "novel/unprecedented" — show the mechanism, don't label it.
- **Do not** keep results that don't serve the central story in the main text.
