Following the publication of this article, the authors regretfully found two errors in the article and would like to make corrections:


In Figure 1b, the 1st image of hBMSCs was chosen incorrectly. In Figure 5a, the 2nd image in the first row (Day 0, PBS) was chosen incorrectly. This mistake occurred due to the carelessness in picking the representative images when the authors tried to compare the morphology for hBMSCs and hEMSCs (Fig. 1b), as well as 18F-FDG uptake between different treatments for Fig. 5a during the figure compilation process.

Cultivation and identification of hEMSCs. a Schematic illustration of isolating and culturing of human endometrium-derived stem cells (hEMSCs). b Representative phase-contrast morphological observation of human bone marrow mesenchymal stem cells (hBMSCs) and hEMSCs cultured up to passage 3 after isolation from premenopausal donors (30–50 years old). c Representative histogram plots of cell surface markers from hEMSCs and hBMSCs. d Comparison of % positive cells of hEMSCs and hBMSCs. Data are expressed as mean ± SEM. n = 3/group

Changes in cardiomyocyte glucose metabolism after MI and hEMSC implantation. Cardiomyocyte glucose metabolism was assessed by 18F-FDG uptake using microPET at baseline, and at 0 and 28 days after cell transplantation. a Representative transverse, coronal and sagittal 18F-FDG uptake images in nude rats that received injection of PBS (PBS control), human bone marrow mesenchymal stem cells (hBMSCs), or human endometrium-derived stem cells (hEMSCs). b A pie-shape heart map was used for analysis of cellular metabolism. c Quantification of 18F-FDG uptake in the apical regions among the three groups. The increase in the uptake of 18F-FDG in the apical regions was highest in the hEMSC group. Data are expressed as mean ± SEM. n = 3/group


The corrected 1st image in Fig. 1b, as well as the corrected 2nd image in the first row (Day 0, PBS) in Fig. 5a, is given in this article.
