Generation of two induced pluripotent stem cell lines from patients with Li-Fraumeni Syndrome carrying TP53 mutation

Summary

Li-Fraumeni syndrome (LFS) is a rare autosomal dominant inherited genetic disorder that greatly increases the risk of developing several types of cancer, including young children and young adults. LFS is primarily caused by specific mutations in the tumor suppressor gene TP53. In this study, we successfully generated two human induced pluripotent stem cell (iPSC) lines derived from patients diagnosed with LFS, each carrying a distinct heterozygous mutation in the TP53 gene. These LFS patient-derived iPSC lines exhibited robust expression of key pluripotency markers, demonstrated the capacity to differentiate into all three germ layers (endoderm, mesoderm, and ectoderm), and maintained a normal karyotype. The establishment of these iPSC lines provides a valuable tool for modeling LFS in vitro, enabling researchers to investigate the underlying pathological mechanisms associated with the disease across various cell types and tissues.
