The intricate neural circuit of the retina forms bioelectric impulses as the origin of vision, and the early development of the retina is a highly complex and coordinated process. Evidence shows that stem cells derived human retinal organoids (hROs) can faithfully recapitulate the embryonic developmental process of the human retina. The emergence of hROs deepens the understanding of early development of the human retina.
The intricate neural circuit of retina extracts salient features of the natural world and forms bioelectric impulse as the origin of vision. The early development of retina is a highly complex and coordinated process in morphogenesis and neurogenesis. Increasing evidence indicates that stem cells derived human retinal organoids (hROs) in vitro faithfully recapitulates the embryonic developmental process of human retina no matter in the transcriptome, cellular biology and histomorphology. The emergence of hROs greatly deepens on the understanding of early development of human retina. Here, we reviewed the events of early retinal development both in animal embryos and hROs studies, which mainly comprises the formation of optic vesicle and optic cup shape, differentiation of retinal ganglion cells (RGCs), photoreceptor cells (PRs) and its supportive retinal pigment epithelium cells (RPE). We also discussed the classic and frontier molecular pathways up to date to decipher the underlying mechanisms of early development of human retina and hROs. Finally, we summarized the application prospect, challenges and cutting-edge techniques of hROs for uncovering the principles and mechanisms of retinal development and related developmental disorder. hROs is a priori selection for studying human retinal development and function and may be a fundamental tool for unlocking the unknown insight into retinal development and disease.
