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

Cell Reports uses professional editors within the Cell Press family. The editor tests whether the work offers a rigorous, complete biological advance for the journal's broad scope and whether a transfer or specialist Cell Press title provides the better route. During review, the editor may be recruiting specialists, waiting for reports, assessing portable reviews, or synthesizing a decision while the author sees one unchanged label. Treat the status as a process category, then use elapsed time and messages to decide the next action.

At Cell Reports a scientific editor is assigned to handle each submission, evaluates it against the journal's editorial criteria, and discusses it with the editorial team. When a manuscript moves between Cell Press journals through a transfer link, the reviewer reports and identities travel with it. The editor evaluates broad-biology significance, mechanism-or-discovery quality, and Cell Press family routing.

Cell Reports is a broad-biology Cell Press title, accepting work that is rigorous but not necessarily at the mechanism-depth bar of Molecular Cell or Cell. The Cell Reports handling editor balances two parallel filters: rejecting clearly out-of-scope work and considering transfers from other Cell Press journals.

Cell Press editorial culture at Cell Reports is decisive: most rejections happen at the handling editor read within 5 to 10 days. Papers that pass the handling editor stage have cleared the Cell Press filter.

Cell Press does not publish a glossary of Editorial Manager status labels or stage durations. The table below is Manusights interpretation, and the labels in your own record may differ.

Before the paper reaches external reviewers, a Cell Press handling 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 handling editor concluded that the work is too narrow for the broad-biology audience or that the methodological rigor is insufficient.

Cell Reports also considers transfers from other Cell Press journals where the receiving handling editor at Cell Reports decides the work fits the broader-biology scope.

The editorial path runs in roughly this sequence, though some stages overlap and the transfer step is invisible to the author:

• Day 0 to 2, administrative check: Cell Press does not publish its administrative checks. At initial submission it requires a completed declaration of interests form and says the formatting requirements for final files do not need to be met, so treat the following as a sensible self-check: complete files, a cover letter directed to the editor, conflict-of-interest declarations, and ethics-statement documentation.

• Days 2 to 10, handling editor read: The handling editor reads the paper and evaluates broad-biology significance, methodological rigor, and Cell Press family fit.

• Variable timing, transfer consultation (parallel): Papers may arrive through a Cell Press transfer from another Cell Press journal. The Cell Reports handling editor reviews the transferred manuscript with prior reviewer reports preserved and decides whether to invite additional reviewers or proceed with the existing reports.

• Days 10 to 21, reviewer recruitment: Cell Press editors at Cell Reports typically send primary research articles to two or more 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.

• Days 14 to 45, active peer 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 planning range for a first decision after review. Cell Press asks reviewers to assess technical rigor and novelty, including the conceptual advance and the validity of the statistical methods.

• After day 45, editorial synthesis: After reports return, the handling editor synthesizes them. The 30 to 45 day planning range for a first decision 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: Handling 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 reports@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 falls inside the 30 to 45 day planning range for a first decision after review. Reports may already be in editorial synthesis with the handling 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 handling 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 reports@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 handling 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.

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 to assess technical rigor and novelty, including the conceptual advance and the validity of the statistical methods. The table below is Manusights interpretation of likely reviewer focus areas and how to prepare for each.

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 handling editor. When the handling 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.

In our pre-submission review work across Cell Press and broad-biology targets, we see 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 handling 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 handling editor and reviewers assigned to your manuscript.

This page was created from Cell Press's public author guidance at Cell Press author instructions, Cell Press Editorial Manager documentation, Cell Press editorial-speed information (a 5-day median to first editorial decision and the ten days Cell Press journals consider sufficient for a review), our own 30 to 45 day planning range, 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 reports@cell.com handles most queries via the manuscript record.

Cell Press editors select reviewers to cover the conceptual and technical expertise a manuscript needs. About ten days is the usual Cell Press review time, which rewards papers reviewers can quickly contextualize.
