Therapeutic Effect and Location of GFP-Labeled Placental Mesenchymal Stem Cells on Hepatic Fibrosis in Rats

<div>Immunohistochemistry results of <i>α</i>-SMA and TGF-<i>β</i>1 in the different experimental groups. Light-brown coloration in cells means the positive staining results. Immunohistochemical staining for <i>α</i>-SMA and TGF-<i>β</i>1 (20x), with a young rat liver as a negative control (NC), fibrotic animals (group II), fibrotic animals transplanted with hPMSCs (group II) sacrificed at one week, four weeks, eight weeks, or twelve weeks after transplantation (1 w, 4 w, 8 w, or 12 w). Scale bars: 100 <i>μ</i>m.</div>
