PRPF6, located on chromosome 20, is required for the formation of the spliceosome. Mutations in the PRPF6 gene can lead to retinitis pigmentosa (RP), a common inherited retinal disease characterized by progressive degeneration of retinal pigment epithelium and photoreceptors. Here, we generated an induced pluripotent stem cell (iPSC) line carrying the PRPF6 c.

Retinitis pigmentosa (RP) is a common inherited retinal disease characterized by progressive degeneration of the retina, leading to night blindness, progressive vision loss, and constriction of the visual field. Previously, we established a human induced pluripotent stem cell line (CSUASOi006-A) from a RP patient carrying heterozygous PRPF8 (c.C5792T) mutation.

X-linked retinoschisis (XLRS) is a common retinal genetic disease that occurs in juvenile males and causes progressive visual impairment. This presents a schisis in the macula or peripheral retina of bilateral eyes, which has no effective treatment. Here, we introduced the RS1 (c.

Background: X-linked juvenile retinoschisis (XLRS) is an inherited disease caused by RS1 gene mutation, which leads to retinal splitting and visual impairment. The mechanism of RS1-associated retinal degeneration is not fully understood. Besides, animal models of XLRS have limitations in the study of XLRS.

Inherited retinal diseases (IRDs) can induce severe sight-threatening retinal degeneration and impose a considerable economic burden on patients and society, making efforts to cure blindness imperative. Transgenic animals mimicking human genetic diseases have long been used as a primary research tool to decipher the underlying pathogenesis, but there are still some obvious limitations. As an alternative strategy, patient-derived induced pluripotent stem cells (iPSCs), particularly three-dimensional (3D) organoid technology, are considered a promising platform for modeling different forms of IRDs, including retinitis pigmentosa, Leber congenital amaurosis, X-linked recessive retinoschisis, Batten disease, achromatopsia, and best vitelliform macular dystrophy.

X-linked retinoschisis (XLRS) is one of the most common retinal genetic diseases with progressive visual impairment in childhood affecting males. It is manifested with macular and/or peripheral schisis in neural retinas with no effective treatment. Previously, we successfully generated a human-induced pluripotent stem cell (iPSC) line from an XLRS patient carrying the hemizygous RS1 c.

The three-dimensional (3D) retinal organoids (ROs) derived from human induced pluripotent stem cells (hiPSCs), mimicking the growth and development of the human retina, is a promising model for investigating inherited retinal diseases. However, the efficient generation of homogenous ROs remains a challenge. Here we introduce a novel polydimethylsiloxane (PDMS) microwell platform containing 62 V-bottom micro-cavities for the ROs differentiation from hiPSCs.

Retinitis pigmentosa (RP) is one of the most common inherited retinal diseases characterized by nyctalopia, progressive vision loss and visual field contraction. we previously generated an induced pluripotent stem cell line (CSUASOi004-A) from a RP patient with heterozygous PRPF6 c.2699 G>A (p.

Article Synopsis
  • - Type 2 diabetes mellitus (T2DM) primarily results from insulin resistance and not enough insulin production, making up 90% of global diabetes cases.
  • - The study introduces a patient-specific human induced pluripotent stem cell line, CSUASOi010-A, created from the peripheral blood mononuclear cells of a 62-year-old woman with T2DM.
  • - The reprogramming of the patient's blood-derived cells was achieved using the Sendai virus technique.

Aim: To study the factors protecting against diabetic retinopathy (DR) in patients with over a decade-long history of type 2 diabetes mellitus.

Methods: A total of 490 patients with type 2 diabetes mellitus lasting for ≥10 years were divided into DR and no diabetic retinopathy (no DR) groups. Their basic information was collected, including age, sex, and duration of diabetes mellitus, as well as pertinent laboratory data.
