Eye embryology
Tīmeklis2024. gada 28. sept. · The human eye begins to develop during the 17th day of gestation. Mesoderm cells, the middle layer of the blastoderm, and ectoderm cells, the outer layer of the blastoderm, form the eye fields in the neural area of the embryo. Optic vesicles develop in the eye fields and in five days, infold to form the optic cup. TīmeklisThe eyes enable organisms to visually perceive their surroundings. During embryogenesis, the eyes originate as outpocketings of the brain and our work aims to elucidate the key stages of eye development. These include induction of the eye field, outgrowth and morphogenesis of the optic vesicles, formation and closure of the …
