Mesoderm is the The middle part of the three germ layers and a derivative of a blastocyst inner cell mass. The mesodermal layer is composed of cells that have the ability to differentiate into muscle and bone cells, as well as kidney cells ,ligaments and connective tissues.(21776284)

For humans, the mesoderm is among the 3 primary germ cell layers. The other two germ layers are endoderm and the ectoderm. In the early stages of an embryo the mesoderm area is the central layer.The Mesoderm layer forms during gastrulation and lies between the ectoderm and the endoderm.(23249260)

It leads to development of some glands and also helps give rise to several other vital structures and tissues including cartilage,bone,connective tissue, muscle, blood for vascular system, reproductive,urinogenital and excretory systems. Stem cells in mesodermal tissues keep the ability to differentiate in varied ways. For instance, Bone marrow stem cells “mesoderm” can become liver cells “endoderm”.(24847885)

The mesoderm can be identified with 3 germ layers seen in the embryo of all “Bilaterian” creatures. That includes all creatures on Earth with the exception Cnidarians,Placozoans and sponges making them triploblastic. The NODAL indicator helps to mediate the initial formation of the mesoderm layer.
