The derivation of diploid human pluripotent stem cell lines from either human blastocysts or embryonic gonads in 1998 attracted a great deal of interest because of the widespread potential applications of these cells in research and in regenerative medicine. Since the initial reports, there has been some progress in the characterisation of blastocyst-derived stem cells, and some technical advances in their manipulation. Conditions for differentiation in vitro of pluripotent stem cells from either blastocysts or gonads have been defined. In some studies, committed progenitor cell populations have been isolated from mixed cultures of differentiating ES cells.

A human induced pluripotent stem cell (iPSC) line was generated from patient with Kennedy Disease (KD), who carried the CAG repeat expansion mutation in AR gene. Peripheral blood mononuclear cells (PBMCs) were reprogrammed using non-integrating delivery of KFL4, OCT4, SOX2, BCL-XL and c-MYC. The iPSC line expresses pluripotency markers, displays a normal karyotype, and is capable of differentiate into three germ layers in vitro.

Mutations in the PRPF31 gene are a well-known cause of autosomal dominant retinitis pigmentosa (RP), the most prevalent genetic form of blindness in adults, affecting 1 in 4,000 individuals globally. In this study, peripheral blood mononuclear cells from a patient carrying a heterozygous mutation in PRPF31 were reprogrammed to generate the human iPSC line ESi132-A. This cell line was thoroughly characterized for self-renewal and pluripotency.

Background: Undifferentiated embryonic cell transcription factor 1 (UTF1) is predominantly expressed in pluripotent stem cells and plays a vital role in embryonic development and pluripotency maintenance. Despite its established importance in murine models, the role of UTF1 on human induced pluripotent stem cells (iPSCs) has not been comprehensively studied.
Methods: This study utilized CRISPR/Cas9 gene editing to create UTF1 knockout in human fibroblasts and iPSCs.
Autosomal-recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is an early-onset neurodegenerative disease caused by mutations in the SACS gene. The first two mutations were identified in French Canadian populations 20 years ago. The disease is now known as one of the most frequent recessive ataxias worldwide.

Chemical reprogramming enables the generation of human pluripotent stem (hCiPS) cells from somatic cells using small molecules, providing a promising strategy for regenerative medicine. However, the current method is time consuming, and some cell lines from different donors are resistant to chemical induction, limiting the utility of this approach. Here, we developed a fast reprogramming system capable of generating hCiPS cells in as few as 10 days.
