In this article (Clin Cancer Res 2009;15:), which was published in the August 1, 2009, issue of Clinical Cancer Research (1), there was an error in the flow-cytometric analysis of the expression of surface antigens on adipose-tissue-derived mesenchymal stem cells (AT-MSCs) and umbilical-cord-blood-derived MSCs (UC-MSCs).
The first sentence of the Results section on page 4929 should read as follows:
Fluorescence-activated cell sorting (FACS) analysis of AT-MSCs and UC-MSCs showed that the AT-MSCs and UC-MSCs expressed MSC-specific cell-type markers, including CD29, CD49d, CD90, and CD105, but did not express cell-type-specific markers for hematopoietic stem cells (HSCs), including CD34 and CD45 (Fig. 1).
CD90 was mischaracterized in Fig. 1 and the Fig. 1 legend on page 4926. The corrected figure and legend appear here:
Flow-cytometric analysis of the expression of surface antigens on adipose-tissue–derived mesenchymal stem cells (AT-MSCs) and umbilical-cord-blood–derived MSCs (UC-MSCs). MSC-specific markers, including CD29, CD49d, CD90, and CD105, were expressed in AT-MSCs and UC-MSCs, whereas hematopoietic stem cell markers, including CD34 and CD45, were not.
