Figure Lengend Snippet: Effect of RhiPSC culture conditions on cloning efficiency. (A) Representative images of alkaline phosphatase-stained colonies from RhiPSC line M6 clone 16.02 on mouse embryonic fibroblasts (MEFs), Matrigel, or Vitronectin in UPPS medium with either no supplement, Y-27632, or CEPT. Scale bar, 100 µm. (B) Graph depicting percent (%) cloning efficiency (y-axis) of alkaline phosphatase-positive colonies cultured on different matrices (x-axis) in UPPS medium with no supplement (circles), Y-27632 (squares), or CEPT (triangles). Individual data points correspond to the mean (dashed lines) % cloning efficiency of RhiPSC colonies counted among six technical replicates per cell line (M4 clone 14.09, red; M6 clone 16.02, pink; W4 clone 14.06, black; W6 clone 5.07, grey). Black brackets indicate statistically significant differences between two supplement types within a substrate group; black lines indicate statistically significant differences between two substrates with the same supplement. p < 0.05 is considered statistically significant. Tukey’s multiple comparisons post-hoc p-values: a=0.0488, b=0.0098, c=0.0097, d=0.0133, e=0.0177, f=0.0483, g=0.0166.

Article Snippet: After 5 days, colonies were stained with a Vector Blue Alkaline Phosphatase Substrate kit (Vector Laboratories, cat. no. SK-5300) as described in .

Figure Lengend Snippet: Characterization of RhiPSC line W6 clone 5.07. (A) Amplicon sequencing of MAPT R406W with wild-type C allele indicated in the black box with a red arrow compared to reference genome (ref). (B) Phase contrast image of colonies grown on MEFs and (C) positive alkaline phosphatase staining; scale bar, 100 µm. (D) RT-PCR detection of endogenous pluripotent mRNAs POU5F1 , SOX2 , NANOG , KLF4 , LIN28 , and MYC . ACTB was used as a reference gene. (E) Amplification of EBNA and oriP in RhiPSCs at P16, no template control (NTC), and the rhesus embryonic stem cell line r420 (RhESC). Plasmid EM2K was used as a positive control (PC) for the detection of EBNA and oriP. (F) Positive immunofluorescence staining for pluripotency proteins SOX2 (green), OCT4 (red), and NANOG (far red), colocalized with DAPI (blue). Scale bar, 100 µm. (G) Flow cytometry-detected APC-A+ cells were 94.5% positive for SOX2, 99.2% positive for OCT4, and 95% positive for NANOG. (H) Short tandem repeat (STR) analysis confirmed (+) RhiPSC line identity. Mycoplasma (Myco.), Herpes B Virus (HBV), Simian Immunodeficiency Virus (SIV), Simian T-Lymphotropic Virus (STLV), and Simian Retrovirus (SRV) were not detected (-). (I) Normal 42,XX karyotype at P12. (J) H&E staining of a teratoma containing endoderm, mesoderm, and ectoderm. Scale bar, 100 µm.
