Open Access Agreement

Upon submitting a paper to Blood Research, authors are asked to declare their agreement to abide by the open access Creative Commons license 3.0. Contents of articles may be copied, distributed, and displayed without charge. Commercial use of the contents or their derivatives is also free of charge. However, the original authors must be given the credit for any reuse or distribution, and the license terms of the article must be made clear. Conditions of any kind can be waived if the authors give permission. For more information regarding the Open Access Agreement, please visit

Authorship: According to criteria formulated by the International Committee of Medical Journal Editors (ICMJE), authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; and 3) final approval of the version to be published. Authors should meet these 3 criteria. All other contributors who do not meet these criteria for authorship should be noted in the Acknowledgments section.

Conflict-of-Interest Statement: Authors must disclose any commercial or other associations that might pose a conflict of interest in connection with the submitted article. All funding sources supporting the work, and institutional or corporate affiliations of the authors, should be acknowledged in the title page.

Copyright: Authors should submit Copyright Transfer Agreement to the Editorial Office at the time of manuscript submission. This transfer will ensure the widest possible dissemination of information.

Registration of Clinical Trial Research: All clinical trials must be registered in a public registry prior to submission. The journal follows the trials registration policy of the ICMJE ( and considers only trials that have been appropriately registered before submission.

Research and Publication Ethics: All human and animal studies must have been approved by the author's Institutional Review Board (IRB). Copies of written informed consents and IRB approval for clinical research should be kept. Clinical research should be done in accordance of the Ethical Principles for Medical Research Involving Human Subjects, outlined in the Declaration of Helsinki ( Clinical studies that do not meet the Declaration of Helsinki will not be considered for publication. Human subjects should not be identifiable, such that patients' names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed. For animal subjects, research should be performed based on the National or Institutional Guide for the Care and Use of Laboratory Animals, and the ethical treatment of all experimental animals should be maintained.
Selection and description of participants clearly describe the selection of observational or experimental participants (healthy individuals or patients, including controls), including eligibility and exclusion criteria and a description of the source population. Because the relevance of such variables as age, sex, or ethnicity is not always known at the time of study design, researchers should aim for inclusion of representative populations into all study types and at a minimum provide descriptive data for these and other relevant demographic variables. Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should define how they determined race or ethnicity and justify their relevance. Authors should use neutral, precise, and respectful language to describe study participants and avoid the use of terminology that might stigmatize participants.

Originality and Duplicate Publication: All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. Any part of the accepted manuscript should not be duplicated in any other scientific journal.
For the policies on research and publication ethics that are not stated in these instructions, the Good Publication Practice Guidelines for Medical Journals ( or the Guidelines on Good Publication Practice ( can be applied.

Reporting Guidelines for Specific Study Designs: It is recommended for authors to follow the reporting guidelines for the specific study design, such as randomized control study (ie, CONSORT), study of diagnostic accuracy (ie, STARD), meta-analyses and systematic reviews of randomized controlled trials (ie, PRISMA), meta-analyses and systematic reviews of observational studies (ie, MOOSE), and observational studies (ie, STROBE). The details are available on the website at

After a manuscript is submitted, the Associate Editor of the relevant area reviews and sends the manuscript to two or more peer reviewers in the corresponding field. On the basis of the comments of the reviewers, the Associate Editor primarily determines whether the article is acceptable or not. A decision is made as "acceptance", "minor revision", "major revision" or "rejection. The author can check the status and the results of the review on the online system. After revising the manuscript, the author should upload the revised files with a reply to each item of the reviewers' opinion. Failure to resubmit the revised manuscript within 90 days is regarded as a withdrawal. Based on the opinion of the Associate Editor, the Editor-in-Chief will make a final decision on the approval for publication of the finally revised manuscripts and can request any further corrections or revisions if necessary. Statistical editing may be done if the data need professional statistical review by a statistician. The final revised manuscript should be submitted within 1 week of the request. If a manuscript is accepted for publication, the author will receive an acceptance letter by e-mail. The order of publication is the duty of the Editor-in-Chief. Any errors discovered in the articles after publication should be notified to the Editorial Office and be inserted in Erratum.

Similarity Check
Similarity Check is a multipublisher initiative to screen published and submitted content for originality. To find out more about Similarity Check, visit All manuscripts submitted to Blood Research are subject to screening using the iThenticate tool for textual similarity to other previously published works.

General Text Style
  • Nomenclatures: For medicine, use generic names. If a brand name should be used, insert it in parentheses after the generic name. Do not use the symbols ⓡ or TM unless necessary. The name of genes (not the proteins) and microorganism should always be italicized, e.g., BCR-ABL mutations, HER2 gene, and E. coli.
  • Statistical Expression: Mean and standard deviation should be described as mean±SD, also mean and standard error as mean±SEM. P should be uppercase and italicized to indicate statistical significance.
  • Units: SI units (International System of Units) should be used. Unit for volume is 'L', instead of 'l' to avoid the confusion. Leave a space between number and units as 5 mmHg but exceptionally 5% or 36oC is permitted.
  • Numbers: In the text, numbers should be Arabic numerals, except when beginning a sentence. Numbers greater than 999 should have commas, e.g., 10,000.
  • Abbreviations: When using abbreviations, define the abbreviation completely in parentheses at first mention. Do not use non-standard abbreviations in the Title. Common hematological, immunological, molecular, and chemical terms can be used without definition in the Title, Abstract, Text, Tables, and Figure legends, e.g., RBC, WBC, ALL, AML, CML, CLL, IgG, HLA, ELISA, AIDS, DNA, cDNA, RNA, mRNA, PCR, bp, kb, and kDa. Hb (hemoglobin) and Hct (hematocrit) can be used without definition except in the Title. Other common abbreviations may be used without definition in Tables, e.g., hr (hour), sec (second), min (minute), d (day), wk (week), mo (month), yr (year), N (sample size), P (statistical significance), mL, µL, SD (standard deviation of the mean), and SE (standard error of the mean).
