In this video, we will demonstrate how to isolate retinal stem cells from the ciliary epithelium of the mouse eye and grow them in culture to form clonal retinal spheres. The spheres that are isolated possess the cardinal properties of stem cells: self-renewal and multipotentiality.

This protocol describes how to produce retinal pigment epithelial cells (RPE) from pluripotent stem cells. The method uses a combination of growth factors and small molecules to direct the differentiation of stem cells into immature RPE in fourteen days and mature, functional RPE after three months.

This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.

Subretinal injection has been widely applied in preclinical studies of stem cell replacement therapy for age-related macular degeneration. In this visualized article, we describe a less risky, reproducible and precisely modified subretinal injection technique via the trans-scleral approach to deliver cells into rat eyes.

Stem cell-derived retinal pigment epithelium (RPE) cells may be used for multiple applications including cell-based therapies for retinal degeneration, disease modeling, and drug studies. Here we present a simple protocol for reproducibly deriving RPE from stem cells.
FAQs
Molecular signals help determine whether cells continue dividing, remain undifferentiated, or begin specializing. These controls are biologically important because expansion without differentiation can preserve a stem-cell population, whereas differentiation produces retinal cell types needed for tissue studies and potential repair. Examining these signals therefore helps researchers connect cell behavior with retinal development and degeneration.
Retinal stem cell regenerative capacity is not constant across biological contexts. The overview indicates that species and developmental stage both influence how much regeneration is possible. Consequently, findings from one organism or life stage may not predict behavior in another. Comparing these contexts helps biologists identify which aspects of retinal repair are broadly conserved and which depend on biological setting.
Studying how retinal stem cells shift between maintenance and differentiation can clarify why similar cells may support development but respond differently after degeneration or injury. The key question is not simply whether cells can produce retinal cell types, but how their potential is controlled under different biological conditions. This distinction is central to explaining variable regenerative outcomes.
Researchers can incorporate retinal stem cells into organoid models to study retinal development and disease-related processes in a structured research system. These models help investigators examine how molecular signals affect proliferation, maintenance, and differentiation while tracking the retinal cell types generated. Organoid studies therefore connect cellular behavior with broader questions about retinal biology and repair.
They provide a way to investigate cellular changes associated with retinal degeneration and injury, including how molecular regulation affects the persistence or differentiation of stem-like populations. This work can clarify why retinal repair differs across contexts and can guide studies of cells that might replace those lost through inherited degeneration or damage.
By defining how their potential is controlled, researchers may improve the scientific basis for cell-based strategies aimed at replacing retinal cells lost through injury or inherited degeneration. The relevant outcome is not merely generating cells in culture, but determining whether regulated proliferation and differentiation can support meaningful repair. This places retinal stem cell research at the intersection of biology and regenerative medicine.
