(A) HFKs, HBECs, and PrECs expanded with the EpiX medium over 40 PDs
retained diploid karyotypes.
(B) EpiX-expanded HFKs did not form tumors after 12 weeks in female nude
mice (1 × 107 cells per mouse, n = 6 in each group). Data are
represented as mean ±SD, n = 6.
(C) Data analysis workflow for whole-genome sequencing.
(D) Distributions of de novo SNVs identified by whole
genome-sequencing in late-passage HFK and CF samples. Venn diagram showed the
overlap between the CF and HFK samples.
(E) Genes that were affected by missense de novo SNV
(all heterozygous) after 40 PDs expansion in the EpiX medium. Two separate
missense SNVs were found in the DDX11 gene in the CF and HFK
samples.
