In the article entitled “Flow Cytometric Characterization of Hematopoietic Stem and Progenitor Cell Subpopulations in Autologous Peripheral Blood Stem Cell Preparations after Cryopreservation” [Transfus Med Hemother. 2023;50(5):417–27; DOI: 10.1159/000533624] by Heuer et al., following the publication, the authors identified that the recovery rate of the CD34+ cells in the article had been calculated incorrectly. The authors identified that the applied dilution factor was inaccurate. This was due to a change in the flow cytometry methodology several years ago, which had not been properly taken into account. The authors then recalculated all related values and revisions to the following sections of the article have been made:
Results – CD34+ Cell Enumeration
Results – Analysis of HSPC Subpopulations (paragraph 1)
Results – Correlation of HSPC Subpopulations with Clinical Data (final paragraph)
Discussion – CD34 Assessment after Cryopreservation
Conclusions and Key Findings – Point 2
These changes do not affect the main conclusions of the article. The original online article has been updated to reflect this and the original article is archived and stored from the journal.
