[Corrigendum] Effect of Yi Guan Jian decoction on differentiation of bone marrow mesenchymal stem cells into hepatocyte­like cells in dimethylnitrosamine­induced liver cirrhosis in mice.

Following the publication of the above article, an interested reader to the authors' attention that there appeared to be several duplications of data panels featured within Figs. 1­3. After having consulted their original data, the authors have realized that a number of the data panels were inadvertently assembled incorrectly in these figures. The corrected versions of Fig. 1A (showing the correct data for the NC­2W and NC­4W experiments), Fig. 1B (including the correct data for the C­4W, M­2W, NC­2W and NC­4W experiments), Fig. 2 (showing the correct data for the YGD­2W experiment), Fig. 3A (NC­3W data panel corrected), Fig. 3B (HGF­1W and NC­3W data panels corrected) and Fig. 3C (C­4W data panel corrected) are shown on the next four pages. All these corrections were approved by all authors. The authors regret that these errors were not resolved before the publication of the paper, thank the Editor of Molecular Medicine Reports for granting them the opportunity to publish this corrigendum, and apologize to the readership for any inconvenience caused.

Effect of Yi Guan Jian decoction on differentiation of bone marrow mesenchymalstem cells into hepatocyte-like cells in dimethylnitrosamine-induced liver cirrhosis in mice.

Yi Guan Jian decoction (YGD) may induce the differentiation of bone marrow mesenchymal stem cells (BMSCs) into hepatocyte-like cells (HLCs); however, the underlying mechanisms remain to be elucidated. The present study aimed to investigate this process. To do this, a dimethylnitrosamine (DMN)-induced liver cirrhosis mouse model was established. The mice from the model group were randomly divided into three subgroups: i) Negative control, ii) hepatocyte growth factor and iii) YGD. The overall health, liver function and histological alterations were monitored. The expression of α­smooth muscle actin (α­SMA), C­X­C chemokine receptor type 4 (CXCR4), extracellular signal­regulated kinase (ERK1/2), nuclear factor κB p65 subunit (NF­κB p65) and ß­catenin were measured by immunohistochemistry, western blotting and reverse transcription­quantitative polymerase chain reaction. Following administration of DMN, the overall health of the mice significantly decreased, with an increase in pathological developments and liver damage resulting in a decrease in liver function. Immunohistochemistry revealed that the expression of α­SMA, CXCR4, ERK1/2, NF­κB p65 and ß­catenin was upregulated. Following treatment with YGD, the overall health, liver function and pathology improved. The mRNA and protein expression levels of CXCR4 and ERK1/2 were upregulated, where as α­SMA, NF­κB p65 and ß­catenin levels were downregulated. The results demonstrated that YGD may induce the differentiation of BMSCs into HLCs to reverse DMN­induced liver cirrhosis; this may be achieved via an upregulation of the SDF­1/CXCR4 axis to activate the mitogen activated protein kinase/ERK1/2 signaling pathway.
