Generation of an iPSC line from a patient with tyrosine hydroxylase (TH) deficiency: TH-1 iPSC.
Fibroblasts from a male patient with compound heterozygous variants in the tyrosine hydroxylase gene (TH; OMIM: 191290; c.[385-CtextgreaterT]; [692-GtextgreaterC]/p.[R129*]; [R231P]),the rate-limiting enzyme for dopamine synthesis,were reprogrammed to iPSCs using episomal reprogramming delivering the reprogramming factors Oct3/4,Sox2,L-Myc,Lin28,Klf4 and p53 shRNA Okita et al. (2011). Pluripotency of TH-1 iPSC was verified by immunohistochemistry and RT-PCR analysis. Cells exhibited a normal karyotype and differentiated spontaneously into the 3 germ layers in vitro. TH-1 iPSC represents the first model system to study the pathomechanism of this rare metabolic disease and provides a useful tool for drug testing.

Chemically defined conditions for human iPSC derivation and culture.
We re-examine the individual components for human embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC) culture and formulate a cell culture system in which all protein reagents for liquid media,attachment surfaces and splitting are chemically defined. A major improvement is the lack of a serum albumin component,as variations in either animal- or human-sourced albumin batches have previously plagued human ESC and iPSC culture with inconsistencies. Using this new medium (E8) and vitronectin-coated surfaces,we demonstrate improved derivation efficiencies of vector-free human iPSCs with an episomal approach. This simplified E8 medium should facilitate both the research use and clinical applications of human ESCs and iPSCs and their derivatives,and should be applicable to other reprogramming methods.

Erosion of dosage compensation impacts human iPSC disease modeling.
Although distinct human induced pluripotent stem cell (hiPSC) lines can display considerable epigenetic variation,it has been unclear whether such variability impacts their utility for disease modeling. Here,we show that although low-passage female hiPSCs retain the inactive X chromosome of the somatic cell they are derived from,over time in culture they undergo an erosion" of X chromosome inactivation (XCI). This erosion of XCI is characterized by loss of XIST expression and foci of H3-K27-trimethylation�
