Mesoderm
[Gr. mesos - middle; Gr. derma - skin] The middle germ layer, formed in the embryo during gastrulation.
mesoderm -- In animals with three tissue layers (i.e. all except sponges and cnidarians), the middle layer of tissue, between the ectoderm and the endoderm.
mesoderm
(mez-oh-durm) [Gk. mesos, middle + derma, skin]
The middle primary germ layer of an early embryo that develops into the notochord, the lining of the coelom, muscles, skeleton, gonads, kidneys, and most of the circulatory system.
mesoderm The middle layer of cells in embryonic development; gives rise to muscles, bones, and structures associated with reproduction. The middle embryonic tissue layer.
Mesoderm."The mesoderm consists of loosely arranged branched cells surrounded by a considerable amount of intercellular fluid. From it the remaining tissues of the body are developed.
Mesoderm
The mesoderm forms structures associated with movement and support: body muscles, cartilage, bone, blood, and all other connective tissues. Reproductive system organs and kidneys form from mesoderm.
Endoderm ...

mesoderm of the extraembryonic membranes (amnion and allantois), or
primordial germ cells (PGCs)
Step 2
A subset of these cells (at the center of the cluster) begins to express ...
mesoderm The third germ layer, formed in the gastrula between the ectoderm and endoderm; gives rise to connective tissues, muscle, urogenital and vascular systems, and the peritoneum.
The mesoderm forms the somites, the notochord, and the mesenchyme, which give rise to the muscles, circulatory and excretory systems of the body.

mesenchyme - mesodermal cells in a developing embryo with the ability to move freely and individually.
mesomere - blastomere exhibiting a size intermediate between a macromere and a micromere.
As is true for all vertebrates, 3 cell layers are formed these layers are called the ectoderm, mesoderm and endoderm. These form by cell divisions, migrations, and rearrangements and are the forerunners of specialized tissues and organs.
And those cells then can give rise, as I said, to all the different cells of the body and there are three major lineages that are important-the ectoderm, the mesoderm, and the endoderm-and these three divisions make up all the cells of the body, ...
(Science: anatomy, dermatology) Mesodermally derived connective tissue underlying the epithelium of the skin. The deep vascular inner layer of the skin.
Although really simple, flatworms have some advanced structures compared to some other animals. They were the first species to develop mesoderm. That mesoderm tissue develops into organs and muscles as the organism grows.
also known as angiogenetic clusters; masses of splanchnic mesodermal cells found in the yolk sac of amniotes. The first blood forming tissue of the embryo, responsible for red blood cells and vitelline blood vessels.
Diploblast: A lower invertebrate such as jelly fish that are composed of two tissue layers (ectoderm and endoderm) and lacking the third layer (mesoderm) present in higher invertebrates and vertebrates.
