Alternative Names: 1020ips3

Details

Description

This induced pluripotent stem cell line was derived by using episomal vectors to reprogram dermal fibroblasts from a male patient with early onset pattern dystrophy. LEIi019-A is described as having a normal karyotype and a heterozygous variant in the OTX2 gene. Expression of OCT4, NANOG, SOX2, KLF4 and TRA-1-81 in undifferentiated cells has been reported, as have in vitro spontaneous differentiation to endoderm, mesoderm and ectoderm, and directed differentiation to retinal pigment epithelial cells via retinal organoids.

Tissue & Disease as reported

Biopsy Location
Ontology ID: fma7163
Label: Skin
Definition: Nonparenchymatous organ that consists of the epidermis, dermis and sets of hair and nails and which surrounds the entire body. Subdivisions of the skin surround various body parts; as a whole, the skin constitutes the external layer of the body. Examples: There is only one skin.
Tissue for derived iPSC
Disease as reported (Donor)

Derivation Details

Induced Pluripotent Cell Derivation Details

Source Cell Type: CL:0000057
Label: fibroblast
Definition: A connective tissue cell which secretes an extracellular matrix rich in collagen and other macromolecules. Flattened and irregular in outline with branching processes; appear fusiform or spindle-shaped.

Source Cell Origin: UBERON:0002067
Label: dermis
Definition: The dermis is a layer of skin between the epidermis (with which it makes up the skin) and subcutaneous tissues, and is composed of two layers, the papillary and reticular dermis[WP].
