        <owl:annotatedTarget>Mesodermal cells are pluripotent and the most abundant in the human body. They contribute to the development of several structures such as the skeletal muscles, bones, heart and blood vessels, kidneys, gonads, connective tissues, and certain layers of the skin. Hence, the mesoderm is often regarded as an active and diverse layer due to its role in forming many bodily structures. 
In embryonic development, these cells are instrumental, contributing to the body&apos;s structures through a carefully coordinated sequence of morphogenetic movements. This process forms the complex multicellular architecture of tissues and organs from a simple ball of cells. Without the function of mesodermal cells, the body&apos;s integral structures and systems would cease to form correctly, leading to developmental disorders such as axial mesodermal dysplasia complex</owl:annotatedTarget>
