mesoderm

The mesoderm is one of the three primary layers of cells formed during early embryonic development, the others being the ectoderm and endoderm. It plays a crucial role in developing many structures in the body, such as muscles, bones, the cardiovascular system, and the kidneys. Essentially, the mesoderm acts as a source of various tissues and organs that are essential for the body's structure and function. Its proper formation is vital for healthy development, and any disruptions can lead to significant health issues.
