Abstract

PURPOSE: Cultured retinal pigment epithelium (RPE) may become a therapeutic option for transplantation in retinal disease. However maintaining a native RPE phenotype in vitro has proven challenging. The human RPE cell-line ARPE-19 is used widely as an alternative to primary RPE. It is grown in DMEM/F12 medium as standard, but its phenotype is dependent on culture conditions, and many differentiation markers are usually absent. The purpose of this study was to examine how this sensitive phenotype of ARPE-19 can be modulated by growth media with or without the metabolite pyruvate to elucidate better RPE growth conditions. METHODS: ARPE-19 cells at passages p22 to p28 were cultured on filters for up to 3 months in DMEM/F12 or DMEM media with or without pyruvate and 1% fetal calf serum. Assessment of differentiation was performed using pigmentation, immunocytochemistry, protein/mRNA expression, transepithelial resistance, VEGF secretion, and ultrastructure. RESULTS: Pyruvate, in combination with DMEM, induced dark pigmentation and promoted differentiation markers such as CRALBP and MerTK. Importantly, RPE65 protein was detected by Western blotting and was enhanced by pyruvate, high glucose, and DMEM. ARPE-19 cells maintained in this medium could also phagocytose human photoreceptor outer segments (POS). VEGF secretion was greater in DMEM cultures and was affected by glucose but not by pyruvate. Pigmentation never occurred in DMEM/F12. CONCLUSIONS: This study demonstrated important differentiation markers, including pigmentation and Western blots of RPE65 protein, and showed human POS phagocytosis in ARPE-19 cultures using a simple differentiation protocol. The results favor the use of high-glucose DMEM with pyruvate for future RPE differentiation studies.

  • Addition of pyruvate in high-glucose DMEM causes ARPE-19 cells to recapitulate key features of RPE cells including RPE-specific differentiation markers, polygonal morphology, polar expression of proteins, extensive microvilli, the ability to phagocytose, and secretion of VEGF.

    “With the addition of pyruvate in high-glucose DMEM, it was shown that ARPE-19 cells recapitulated key features of RPE cells including RPE-specific differentiation markers, polygonal morphology, polar expression of proteins, extensive microvilli, the ability to phagocytose, and secretion of VEGF (Ahmado et al., 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
