Details

Description

This induced pluripotent stem cell line was derived by using episomal vectors to reprogram dermal fibroblasts from a female Central Chorioretinal Atrophy patient. LEIi011-A is described as having a normal karyotype and compound heterozygous variants in the RCBTB1 gene. Expression of OCT4, NANOG, SOX2, KLF4 and MYC in undifferentiated cells has been reported, as has in vitro spontaneous differentiation to endoderm, mesoderm and ectoderm.

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.

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.
