We studied the behavior of retinal pigment epithelial cells from adult human eye derived from different donors in different culturing systems: on plastic, in collagen gel, and on decellularized neural retina substrate. The cells diverge into two subpopulations similar by their morphology and behavior: one subpopulation migrated to the surface of the dense substrate and the other formed spheroid structures consisting of aggregated cells. This fact confirms the data on genetically-predetermined phenotypic heterogeneity of retinal pigment epithelium cells that should be taken into account when using these cells in tissue engineering.
