Nature Reviews Molecular Cell Biology Formatting Requirements: Complete Author Guide

Nature Reviews MCB publishes several formats, all focused on synthesis and expert analysis rather than primary data.

The length for Reviews is flexible and negotiated with the commissioning editor. When you receive your invitation, the editor will provide a target word count and figure number. These aren't rigid caps, but staying within the agreed scope shows respect for the editorial process and for readers. A review commissioned at 8,000 words that arrives at 15,000 will need substantial cutting.

Perspectives offer an author's viewpoint on a current topic. They're shorter and more opinionated than Reviews. They don't need to comprehensively cover an entire field; instead, they present a specific argument or framework.

Understanding the editorial workflow helps you format and write more effectively.

1. Editor contacts you with a topic proposal (or you send a pre-submission inquiry)
2. Scope discussion: you and the editor agree on the angle, length, figure count, and timeline
3. Annotated outline: you submit an outline with proposed section headings and figure concepts
4. Editor feedback on outline: this stage catches scope issues before you invest writing time
5. Full draft submission: you write the manuscript and submit rough figure drafts
6. Peer review: typically 2-3 expert reviewers, 1-2 rounds
7. Revision: incorporate reviewer and editor comments
8. Figure production: the art team redraws all figures
9. Author proofs: you check the text and redrawn figures
10. Publication

The annotated outline stage is unusual but extremely valuable. It prevents you from spending months writing a review only to discover that the editor wanted a different emphasis. Take the outline seriously and include proposed figure concepts (even as rough sketches).

This is the most distinctive formatting feature of Nature Reviews MCB. You don't submit publication-ready figures. Instead, you submit rough drafts, sketches, or diagrams, and the journal's professional art team redraws them in the Nature Reviews house style.

What to submit as figure drafts:

• Clear sketches (hand-drawn or digital) showing the concept you want illustrated
• Annotated PowerPoint slides or Illustrator files
• Schematic diagrams showing molecular pathways, cellular processes, or conceptual frameworks
• Tables of data that you want converted into visual summaries
• Published figures (with permission) that you want adapted or updated

Guidelines for figure drafts:

• Label every element clearly so the artist understands what each part represents
• Include a written description of each figure alongside the draft
• Specify which elements are essential and which are flexible
• Indicate preferred layouts (landscape vs. portrait, multi-panel arrangements)
• Don't spend time on making figures look polished; the art team will handle aesthetics

What makes a good Nature Reviews MCB figure:

• Molecular pathway diagrams showing regulatory cascades with clear hierarchy
• Timeline figures showing the evolution of a field or concept
• Comparison panels contrasting normal and disease states
• Multi-level diagrams connecting molecular events to cellular and organismal phenotypes
• Summary tables with visual elements (icons, color coding)

The art team typically takes 4-6 weeks to produce final figures. You'll review the redrawn versions during the proofing stage and can request corrections. The figures in Nature Reviews MCB are recognizable for their consistent visual style, which is part of the journal's brand.

Nature Reviews MCB uses the standard Nature reference style.

Key formatting rules:

• References numbered in order of first appearance
• Superscript numbers in text, placed after punctuation
• Up to 5 authors listed; for 6+, list first 5 followed by "et al."
• Journal names abbreviated using standard abbreviations
• Volume in bold, page range follows, year in parentheses

Example journal article:

1. Zhang, Y., Liu, T., Chen, W., Patel, S. R. & Williams, J. K. Phase separation drives chromatin remodeling in pluripotent stem cells. Nat. Rev. Mol. Cell Biol. 27, 312-328 (2026).

Example book reference:

1. Alberts, B. et al. Molecular Biology of the Cell 7th edn (W. W. Norton, 2025).

Nature Reviews articles tend to have extensive reference lists, often 150-300 references for a comprehensive Review. There's no formal cap, but the editor will flag reference lists that seem excessive relative to the scope. Every reference should be directly relevant; don't pad the list with tangential citations.

The reference list should be current. Nature Reviews MCB editors expect reviews to cover the literature comprehensively through the date of submission, including preprints where they represent important contributions.

Nature Reviews MCB Reviews include a brief abstract (typically 150-200 words, unstructured) that summarizes the scope and main conclusions of the review.

The abstract should:

• State what topic the review covers and why it matters now
• Highlight the main advances or emerging themes discussed
• Indicate the review's unique contribution (new framework, synthesis of conflicting data, identification of open questions)

Unlike primary research abstracts, review abstracts don't describe methods or present original data. They frame the review's scope and intellectual contribution.

Some Reviews also include a "Key points" box with 4-6 bullet points summarizing the main takeaways. These appear in a highlighted box in the published article and serve as a quick reference for readers. The editor will tell you whether Key points are needed for your article type.

Word is the standard and strongly preferred format for Nature Reviews MCB.

Word submissions:

• Use the Nature Portfolio Word template if available
• Times New Roman, 12-point, double-spaced
• Number all pages
• Line numbers encouraged but not always required
• Figures submitted as separate files (rough drafts, any format)
• Reference list at the end of the document

LaTeX submissions:

• Accepted but uncommon for this journal
• The content is entirely text and references (no equations or complex notation)
• If you prefer LaTeX, the nature.cls template works
• Will be converted to Word during production

Because Nature Reviews MCB publishes reviews and perspectives rather than technical physics or mathematics papers, there's virtually no need for LaTeX's equation-handling capabilities. Word is the practical choice for nearly all authors.

1. Boxes are a signature feature. Nature Reviews MCB Reviews frequently include 1-3 "boxes" that provide focused deep-dives on specific subtopics. These appear as highlighted sidebars in the published article. Common box topics include glossary definitions, technical method explanations, clinical relevance summaries, or historical context. The editor may suggest box topics, or you can propose them. Each box is typically 300-600 words.

2. The timeline matters. When you accept a commission, you agree to a delivery date (usually 3-6 months). Nature Reviews editors are understanding about reasonable delays, but missing the deadline by months can result in the commission being reassigned. If your timeline is slipping, communicate early.

3. Competing interests are scrutinized carefully. Because reviews can influence research directions and funding, Nature Reviews MCB takes competing interest declarations seriously. Declare all relevant relationships, including advisory board memberships, consulting fees, equity holdings, and patents. The editors will ask for clarification if the disclosure seems incomplete.

4. Acknowledgments of peer reviewers. Nature Reviews MCB uses a single-blind peer review model (reviewers are anonymous to authors). The journal sometimes publishes reviewer names with the article, with reviewer consent. This transparency initiative is part of Nature Portfolio's broader open science efforts.

5. Preprint considerations. If you've posted a preprint of your review (which is unusual but not prohibited), disclose this at submission. The editors will assess whether the preprint version affects the review's value to the journal.

6. The figures carry the narrative. In Nature Reviews MCB, figures aren't supplementary to the text; they're co-equal. The best reviews are designed so that a reader could follow the main argument by reading the figure legends alone. Plan your figures at the outline stage, not after writing.

A typical Nature Reviews MCB Review follows this structure:

1. Title (informative, no abbreviations)
2. Author names and affiliations
3. Abstract (150-200 words, unstructured)
4. Key points (4-6 bullets, if requested by editor)
5. Introduction (broad context, why this review now)
6. Main body (organized by topic with descriptive headings)
7. Boxes (1-3 sidebar deep-dives)
8. Conclusions and future directions
9. Acknowledgments
10. Competing interests declaration
11. References
12. Figure drafts (rough sketches/concepts, submitted separately)

The body text should be organized into logical sections with informative headings. Don't use generic headings like "Recent advances" or "Current understanding." Instead, use headings that tell the reader what they'll learn: "Phase separation as a driver of chromatin organization" or "How CRISPR screens revealed new autophagy regulators."

These issues cause the most delays at Nature Reviews MCB:

• Figure drafts that are too vague for the art team to interpret
• Missing figure descriptions (the art team needs written explanations alongside sketches)
• Reference lists that are outdated or missing recent publications
• Boxes that are too long or overlap with the main text
• Abstracts that describe what the review covers rather than what it concludes
• Competing interest declarations that omit relevant relationships
