AI Article Synopsis

  • Friedreich's ataxia (FRDA) is a rare neurodegenerative disease linked to a GAA triplet repeat expansion in the FXN gene.
  • Researchers created induced pluripotent stem cell (iPSC) lines from skin fibroblasts of three different FRDA patients using safe, non-integrating vectors.
  • The generated iPSC lines showed essential characteristics of pluripotency, including normal genetic structure and the ability to differentiate into all three germ layers in a lab test.

Article Abstract

Friedreich's ataxia (FRDA) is a rare neurodegenerative disorder which is caused by triplet repeat expansion (GAA) in the first intron of FXN gene. In this present study, we generated induced pluripotent stem cells (iPSC) lines from fibroblasts of three unrelated FRDA patients using integration-free episomal vectors. All iPSC lines express the pluripotency markers such as OCT4 and SSEA4, display normal karyotypes and can differentiate into all three germ layers via in vivo teratoma formation assay.

Protocol for live imaging of axonal transport in iPSC-derived iNeurons.

Department of Neurology, University Medical Center Goettingen, 37077 Goettingen, Germany. Electronic address:

Studies of human induced pluripotent stem cell (iPSC)-derived neurons promise important insights into neurodegenerative diseases. Here, we present a protocol for live imaging of axonal transport in glutamatergic iPSC-derived neurons (iNeurons). We describe steps for the differentiation of iPSCs into iNeurons via PiggyBac-mediated neurogenin 2 (NGN2) delivery, iNeuron culture and transfection, and the acquisition and analysis of time-lapse images.

  • FT596 is a novel cancer therapy using iPSC-derived CAR NK cells targeting CD19, designed to assess its safe dosage and effectiveness alone and with rituximab in patients with B-cell lymphoma.
  • This phase 1 trial involved patients with relapsed or refractory B-cell lymphoma, administering FT596 after chemotherapy, with separate regimens for those receiving rituximab and those who did not.
  • The study measured potential side effects while determining the optimal dose of FT596 and allowed modifications to the treatment based on patient tolerance and response.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.

Background: Aniridia is a rare panocular disease caused by gene mutation in the PAX6, which is essential for eye development. Aniridia is inherited in an autosomal dominant manner, but its phenotype can vary significantly among individuals with the same mutation. Animal models, such as drosophila, zebrafish, and rodents, have been used to study aniridia through Pax6 deletions.

Generation and heterozygous repair of human iPSC lines from two individuals with the neurodevelopmental disorder, TRAPPC4 deficiency.

Stem Cell Res

Murdoch Children's Research Institute, Parkville, Victoria, Australia; Department of Paediatrics, University of Melbourne, Parkville, Victoria, Australia. Electronic address:

A rare neurodevelopmental disorder has been linked to a well-conserved splice site variant in the TRAPPC4 gene (c.454 + 3A > G), which causes mis-splicing of TRAPPC4 transcripts and reduced levels of TRAPPC4 protein. Patients present with severe progressive neurological symptoms including seizures, microcephaly, intellectual disability and facial dysmorphism.
