This animation describes the formation of endocrine glands starting with the mitosis of mesenchymal tissues, eventually leading to the formation of the secretory portion of the gland by differentiation.

Endocrine glands, also known as ductless glands are part of the endocrine system and are involved in hormonal secretions. The developmental process begins with division, via mitosis, of the mesenchymal cells, which is driven by their interaction with the epithelial cells. The dividing cells form a mass that begins to protrude into and eventually penetrate the connective tissue beneath them. Once inside the connective tissue the mass of mitotic cells form a duct. After some time the mesenchymal cells stop dividing and the duct cells begin to degrade by apoptosis. The remaining cluster of cells will differentiate to become the secretory portion of the gland. The now formed gland will produce hormonal secretions that will directly diffuse into the surrounding blood vessels to be distributed thoughout the body.
