Cell Reports 'Under Review': What Each Status Means and When to Expect a Decision

Before the paper reaches external reviewers, a Cell Press consulting editor at Cell Reports evaluates whether the broad-biology significance and methodological rigor warrant Cell Reports's editorial slots. About 50 to 60 percent of submissions are returned at this stage within 5 to 10 days. A desk rejection most often means the consulting editor concluded that the work is too narrow for the broad-biology audience or that the methodological rigor is insufficient. Cell Reports also accepts transfers from Molecular Cell, Cell Host & Microbe, Immunity, and Neuron where the receiving consulting editor at Cell Reports decides the work fits the broader-biology scope.

The Cell Press editorial office confirms files are complete: manuscript with figures embedded, supplementary information separate, reporting checklists where applicable (ARRIVE for animal work, MIQE for quantitative PCR, CONSORT for any clinical-trial component), STAR Methods compliance documentation, cover letter directed to the editor, conflict-of-interest declarations, and ethics-statement documentation.

The consulting editor reads the paper and evaluates broad-biology significance, methodological rigor, and Cell Press family fit.

In parallel with the consulting editor's primary read, papers may arrive via Cell Press portable peer review transfer from Molecular Cell, Cell Host & Microbe, Immunity, or Neuron. The Cell Reports consulting editor reviews the transferred manuscript with prior reviewer reports preserved and decides whether to invite additional reviewers or proceed with the existing reports.

Cell Press consulting editors at Cell Reports typically invite 2 to 3 external reviewers. The recruitment window can take 5 to 10 days because reviewers with topic-matched expertise across broader biology are scarce. Cell Press journals consider 10 days sufficient time to complete a review.

Once reviewers agree to review, the typical Cell Reports peer-review cycle lasts 10 to 21 days per reviewer, contributing to the 30 to 45-day median first-decision target. Reviewers are asked to evaluate broad-biology significance, methodological rigor, and reproducibility. Reviewer reports for Cell Reports tend to be focused; 1500 to 2500 word reports are typical given the 10-day reviewer target.

After reports return, the consulting editor synthesizes them. The 30 to 45-day median first-decision time applies to papers that reach external peer review.

• Rejection within 1 to 5 days: Administrative issue or immediate scope mismatch.
• Rejection within 5 to 10 days: Consulting editor desk rejection. Most rejections happen here.
• Still Under Review after 2 weeks: Strong signal. Paper passed the Cell Press filter.
• Still Under Review after 8 weeks: Reviewer-recruitment or reviewer-report delay. A polite inquiry to cellreports@cell.com is appropriate.
• Status changes to "Decision Pending": Reports are in; expect a decision within 1 to 2 weeks.

This is the most common anxiety we hear from Cell Reports authors during the active editorial window. The honest answer: no, 5 weeks at Under Review puts you right at Cell Reports's 30 to 45-day median first-decision window. Reports may already be in editorial synthesis with the consulting editor preparing a recommendation. Most reviewer-driven delays come from reviewer-recruitment timing rather than slow reviews, once a reviewer accepts the assignment, reports typically arrive within 10 to 14 days at Cell Reports given the 10-day Cell Press reviewer target. If the portal still says Under Review at the 7-week mark, the most likely explanation is that one of the assigned reviewers asked for an extension and the consulting editor granted it. This is normal practice at Cell Press.

At 5 to 7 weeks, a status inquiry usually helps only if a concrete manuscript-record issue changed: an ethics statement needs correction, a related preprint or accepted article appeared, a reagent or data-accession record changed, or a corresponding-author detail is wrong. If none of those changed, wait until 8 weeks and then send one concise email to cellreports@cell.com with the manuscript ID, title, submission date, current status, and a request for confirmation that review is still active.

If your Cell Reports paper is rejected after review, the natural cascade depends on what the reviewers and consulting editor cited:

Cell Reports Medicine is the most natural Cell Press cascade for clinical-translational papers because Cell Press supports manuscript-transfer with reviewer reports preserved. The transfer process takes 5 to 10 days.

iScience is the Cell Press open-access cascade for technically rigorous broad-biology papers where the open-access publishing model fits.

Communications Biology is a Nature Portfolio open-access cascade option for broad-biology papers where Nature Portfolio reach is preferred. Nature Portfolio operates independently from Cell Press; reports do not transfer, but editors may recognize Cell Press reviewer reports informally.

eLife is a cascade option for papers where the reviewed-preprint publication model is preferred. eLife operates independently with its own pre-review screening.

Cell Press asks reviewers at Cell Reports to evaluate four things specifically. The table below maps each to actionable preparation.

In our pre-submission work with Cell Reports manuscripts, three patterns generate the most consistent reviewer concerns we see at Cell Reports.

STAR Methods documentation gaps surface as reviewer requests for clarification. When STAR Methods documentation is thin (especially for AAV constructs, custom analysis code, or behavioral paradigms), reviewers consistently request expanded methods sections before issuing a final decision. The strongest revisions add detailed STAR Methods documentation with reagent catalog numbers.

Narrow scope flagged for broad-biology fit. When the introduction frames the work too narrowly around one model system or one mechanism, broad-biology framing concerns surface from at least one reviewer. The strongest manuscripts frame the introduction around a broader-biology principle.

Cell Press transfer routing flagged by consulting editor. When the consulting editor concludes the work fits better at Cell Reports Medicine (clinical-translation) or iScience (open-access), transfer offers are common. Cell Press editors take these transfers seriously.

We have reviewed 50+ manuscripts targeting Cell Reports, Molecular Cell, Cell Host & Microbe, Immunity, Neuron, Cell Reports Medicine, and iScience. Full Manusights reviews include a 60-day money-back guarantee, and we do not train models on your manuscript.

Of the 100 manuscripts our team reviewed across Cell Press and broad-biology targets, Manusights internal analysis identifies five recurring preventable risks before peer review: narrow model-system framing, STAR Methods gaps, missing reagent or code traceability, overclaimed mechanism depth, and a transfer plan that is not ready if the consulting editor redirects the paper. Source limitation: official guidance explains Cell Reports article types, status inquiries, submission mechanics, and Cell Press policies, but it cannot diagnose whether your abstract, first figure, STAR Methods section, reagent table, and cover letter satisfy the specific consulting editor and reviewers assigned to your manuscript.

This page was created from Cell Press's public author guidance at cell.com/cell-reports/authors, Cell Press Editorial Manager documentation, Cell Press editorial-speed guidance (5-day desk decision target, 10-day reviewer target, 30 to 45-day median first decision), and Manusights pre-submission review experience with Cell Reports-targeted manuscripts.

For the Cell Press broad-biology landscape beyond Cell Reports, see Molecular Cell (mechanism depth focus), Cell Host & Microbe (host-pathogen specialty), Immunity (immunology specialty), and Cell Reports Methods (methodology focus). The choice across these titles depends on whether the central contribution is broad-biology (Cell Reports), mechanism-depth (Molecular Cell), specialty-focused (Cell Host & Microbe or Immunity), or methodology-development (Cell Reports Methods). For technical issues during Cell Press submission, the editorial office at cellreports@cell.com handles most queries via the manuscript record.

Reviewers at Cell Reports typically draw from one mechanism-focused biology reviewer and one broader-biology specialist. The 10-day Cell Press reviewer target rewards papers reviewers can quickly contextualize.

For a pre-upload check of your manuscript against the Cell Reports broad-biology-plus-methodological-rigor bar before submission, our Cell Reports pre-submission diagnostic flags the STAR Methods gaps and narrow-framing weaknesses most likely to surface in reviewer reports.
