Figure Lengend Snippet: Characterization of the UCSD167i-99-1 hiPSC line. (A) Schematic diagram of the differentiation strategy adopted by with modifications, to induce hiPSC into MP and IM cells. (B–D) Immunofluorescence images of hiPSC colonies stained for POU5F1 (green), NANOG (green), SOX2 (red), merged with nucleus marker DAPI (cyan). Scale bars: 100 μm. (E) Absolute mRNA expression levels of pluripotency markers determined by RT - qPCR analysis in undifferentiated hiPSC colonies. Error bars represent mean ± SEM, n = 3 independent experiments, n.s. not significant, * p < 0.05 , ** p < 0.01, *** p < 0.001, **** p < 0.0001. hiPSC human induced pluripotent stem cells, MP mesoderm progenitor, IM intermediate mesoderm, DE definitive endoderm.
Article Snippet: For this purpose, we adopted the strategy outlined by and investigated the roles of high levels of Nodal and BMP signaling activity, along with WNT signaling, in the determination of IM cells derived from a UCSD167i-99-1 hiPSC line, obtained from the WiCell Research Institute.
