Rapid differentiation of the human RPE cell line, ARPE-19, induced by nicotinamide
Open accessAbstract
Human RPE cell lines, especially the ARPE-19 cell line, are widely-used in eye research, as well as general epithelial cell studies. In comparison with primary RPE cells, they offer relative convenience and consistency, but cultures derived from these lines are typically not well differentiated. We describe a simple, rapid method to establish cultures from ARPE-19 cells, with significantly improved epithelial cell morphology and cytoskeletal organization, and RPE-related functions. We identify the presence of nicotinamide, a member of the vitamin B family, as an essential factor in promoting the observed differentiation, indicating the importance of metabolism in RPE cell differentiation.

ARPE-19 and D407 lines have genetic abnormalities, with triploidy in D407 and an abnormal karyotype in ARPE-19.
“However, these cell lines have genetic abnormalities, with triploidy in the D407 line (Davis et al., 1995), and an abnormal karyotype (most notably, a loss of one copy of chromosome 15, and an unbalanced translocation between the chromosome 15q and 19q) in the ARPE-19 line (Fasler-Kan et al., 2018; Hazim et al., 2019).”

A series of washes with trypsin selectively removes the more proliferative cells, which tend to be more loosely adhered to the substrate, leaving behind firmly attached cells that more readily form a culture with a cobblestone appearance.
“An important part of the protocol, reported by Hazim et al. for ARPE-19 cells, is a series of washes with trypsin that selectively removes the more proliferative cells, which tend to be more loosely adhered to the substrate, leaving behind firmly attached cells that more readily form a culture with a cobblestone appearance (Hazim et al., 2019).”

The pyruvate protocol for ARPE-19 differentiation required 3-4 months, whereas a more recent protocol achieved similar differentiation within 4 weeks through addition of nicotinamide instead of pyruvate.
“These protocols required 3–4 months for RPE differentiation, whereas, a more recent protocol was able to achieve a similar level of differentiation within 4 weeks through the addition of nicotinamide instead of pyruvate (Hazim et al., 2019) (Fig. 5).”

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.
