Loss of function mutations in PARK2 (encoding PARKIN) cause autosomal recessive Parkinson's disease (PD), which often manifests at a juvenile age. Molecular and biochemical studies show that PARKIN functions as an E3 ubiquitin ligase controlling mitochondrial homeostasis. Yet, the exact mechanisms are unclear due to the use of sub-optimal models including cancer cells and fibroblasts. We have generated a PARK2 knockout (KO) isogenic cell line using a well-characterized induced pluripotent stem cell (iPSC) clone with good differentiation potential. This cell line lacks the expression of all PARKIN isoforms and is valuable for elucidating the role of PARK2 mutations in PD.

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.

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.

Complement factor H (CFH) common genetic variants have been associated with age-related macular degeneration (AMD). While most previous in vitro RPE studies focused on the common p.His402Tyr CFH variant, we characterized rare CFH variants that are highly penetrant for AMD using induced pluripotent stem-cell-derived retinal pigment epithelium (iPSC-RPE).

Tissue-engineered vascular conduits (TEVCs) are a promising blood vessel replacement. In a recent publication in Cell Stem Cell, Park et al. developed TEVCs comprised of decellularized human umbilical arteries lined with shear-trained, human induced pluripotent stem cell (hiPSC)-derived endothelial cells (ECs) that resisted thrombosis and exhibited patency upon grafting into the rat inferior vena cava (IVC).
