Experimental Models for Study of Retinal Pigment Epithelial Physiology and Pathophysiology

DOI: 10.3791/2032-v
What you'll learn
  • Culture confluent monolayers of human fetal RPE cells with native tissue physiology
  • Perform eye dissection and RPE isolation from human fetal tissue
  • Characterize RPE polarity, protein expression, and gene patterns in vitro
Protocol

We provide a reproducible method for culturing confluent monolayers of human fetal retinal pigment epithelial cells (hfRPE) cells that exhibit morphology, physiology, polarity, and protein and gene expression patterns of adult native tissue. This work has been extended to an animal model of several eye diseases.

Difficulty
advanced
Total time
~3–5 days (dissection ~1 hour; isolation ~2 hours; culture to confluence ~3–4 days)
Model organism
Human fetal retinal pigment epithelial cells (hfRPE)
Biosafety
BSL-1

Steps

1
Understand retinal pigment epithelium biology and function

Review anatomical and physiological background on RPE tissue, its role in the eye, and the rationale for in vitro modeling of eye diseases.

2
Dissect human fetal eye tissue

Perform careful dissection of the human fetal eye to isolate the retinal pigment epithelium layer for downstream cell culture.

▶ 03:26
3
Isolate and dissociate hfRPE cells

Enzymatically digest and mechanically dissociate the isolated RPE tissue to obtain single-cell suspension suitable for monolayer culture.
