While the current study has shown that ESC-FBs resemble MSCs in producing inflammatory mediators, whether or not they exhibit immune suppressive effects on immune cells through cell-cell interaction is an important question that remains to be addressed. a Senescence analysis of mESC-FBs and BM-MSCs cultured for 7 days. The values in the control group represent the mRNA levels in cells before differentiation. Human embryonic stem cells possess immune-privileged properties. The cellular location of NFκB was detected with an antibody against NFκB under a fluorescence microscope. 2007;110:91–100. The cells within a colony have fairly uniform morphology, as shown in a representative colony (Fig. 2016;7:e2062. The mRNA levels of the tested genes were determined from untreated mESC-FBs and BM-MSCs. 2008;2:141–50. Stem Cells. Mesenchymal stem cells: methods and protocols.

As shown in Fig. mESC-FBs were differentiated from D3 and DBA252 mESCs through a retinoic acid (RA)-induced differentiation protocol and purified based on their rapid adherence to an uncoated cell culture dish as described in our published studies [7, 8]. The potential of mESC-FBs to differentiate to adipocytes, osteocytes, and chondrocytes was assessed by a spontaneous differentiation protocol. Notably, connective tissue growth factor (CTGF), a matricellular protein that has important roles in cell adhesion, proliferation, and tissue repair [37], was expressed much more highly in BM-MSCs than in mESC-FBs. a BM-MSCs (upper panels) and mESC-FBs (bottom panels) were treated with LPS for 60 min or TNFα for 15 min, or left untreated (Con). The cells were fixed and stained with TB and photographed under a phase-contrast microscope, scale bar = 100 μm. The absorbance values were used as an indirect measurement of cell number, or the numbers of cells were counted from photographed images of TB stained cells as described in individual experiments. Garcia MA, Meurs EF, Esteban M. The dsRNA protein kinase PKR: virus and cell control. As shown in Fig. Stem Cells Dev. Wang R, Wang J, Paul AM, et al. Cells were differentiated for up to 4 weeks and were analyzed at the times indicated. Characterization of embryonic stem cell-differentiated fibroblasts as mesenchymal stem cells with robust expansion capacity and attenuated innate immunity. In a direct comparison, our RT-qPCR analysis revealed that mESC-FBs expressed about 10 times lower levels of MHC I than BM-MSCs, while MHC II was barely detected (Fig. Cell Physiol Biochem. Since mESC-FBs differentiated from D3 and DBA mESCs were similar in all properties tested, the experiments in this study were mainly performed with mESC-FBs differentiated from D3 cells and some key experiments were confirmed with the cells differentiated from DBA cells. Furthermore, immunoregulatory properties similar to MSCs have been reported in adult human FBs [17, 18]. Takumi M, Mattson M, Rao M. Cellular lifespan and senescence signaling in embryonic stem cells. https://doi.org/10.1186/s13287-018-1033-8, DOI: https://doi.org/10.1186/s13287-018-1033-8. 1980;124:708–12. J Immunol. Cookies policy. ESCs do not express MHCs and co-stimulatory molecules [32, 33] and are considered to be immune privileged [34]. Differentiation. The graph illustrates growth curves of three representative clones. Because MSCs can differentiate into chondroctyes, myocytes, epithelial cells etc. Values in RT-PCR analysis are mean ± SD of data from three independent experiments. The idea of using MSCs for therapeutic application was originally driven by their tri-lineage differentiation potential to repair damaged tissues.
