ectoderms การใช้

• The brain develops from the ectoderm and blood from the mesoderm.
• The cells in the early primitive ectoderm basically make the embryo,
• The median ocelli develop from a transverse fold of the ectoderm.
• Ectodermal dysplasia describes abnormalities of structures derived from the embryonic ectoderm.
• These cells are also derived from epiblast which is transformed into ectoderm.
• The formation of the neural tube from the ectoderm is called neurulation.
• Meanwhile, the overlying ectoderm secretes bone morphogenetic protein ( BMP ).
• BMP antagonists diffusing from the ectoderm generates a gradient of BMP activity.
• Abnormal ectoderm patterning will cause abnormal and no neural folding.
• Nasal placodes originate on the frontonasal prominence from the ectoderm.
• Mesentoblasts are found in the blastopore area between the endoderm and ectoderm.
• Robins said the cells in the early primitive ectoderm develop in two directions.
• Ectoderm follows a default pathway to become neural tissue.
• They found that ectoderm was more potent than endoderm.
• It is formed by ectoderm and endoderm coming into contact with each other.
• BMP signals from the epidermis inhibit the formation of placodes in nearby ectoderm.
• The ectoderm is the outermost layer of the embryo.
• Each tracheal tube develops as an invagination of the ectoderm during embryonic development.
• Unlike bilaterians, radiata only have two primordial cell layers, endoderm and ectoderm.
• The shells develop from the ectoderm as an organic framework which is subsequently mineralised.
