A germ layer is a primary layer of cells that forms during embryonic development. The three germ layers in vertebrates are particularly pronounced; however...

A germ cell is any cell that gives rise to the gametes of an organism that reproduces sexually. In many animals, the germ cells originate in the primitive...

This is a list of cells in humans derived from the three embryonic germ layers – ectoderm, mesoderm, and endoderm. Trichocyte Keratinocyte Gonadotrope...

is referred to as the germ ring and is made up of a superficial layer, the epiblast which will become ectoderm, and an inner layer called the hypoblast...

they will differentiate into the mesoderm germ layer that, together with endoderm and ectoderm germ layers, will give rise to all the tissues of the adult...

Embryogenesis continues with the next stage of gastrulation, when the three germ layers of the embryo form in a process called histogenesis, and the processes...

formed, three distinct layers of cells (the germ layers) from which all the bodily organs and tissues then develop. The innermost layer, or endoderm, give...

the three primary germ layers in the very early embryo. The other two layers are the ectoderm (outside layer) and mesoderm (middle layer). Cells migrating...

three primary germ layers formed in early embryonic development. It is the outermost layer, and is superficial to the mesoderm (the middle layer) and endoderm...

middle layer of the three germ layers that develops during gastrulation in the very early development of the embryo of most animals. The outer layer is the...

three germ layers; the endoderm (inner layer), mesoderm (middle layer), and ectoderm (outer layer). As seen in the figure below, each germ layer will become...

was concluded that the germ layers are simultaneously formed during the cellularization process. This is in contrast to germ layer theory in which ectoderm...

Diploblasty is a condition of the blastula in which there are two primary germ layers: the ectoderm and endoderm. Diploblastic organisms are organisms which...

Primordial germ cell (PGC) migration is the process of distribution of primordial germ cells throughout the embryo during embryogenesis. Primordial germ cells...
