MESOBLAST Meaning and
Definition
-
Mesoblast refers to a layer of cells in the developing embryo or the middle layer of tissue in certain organisms. Derived from the Greek words "meso" meaning middle and "blast" meaning bud or germ cell, the term mesoblast is primarily used in the field of developmental biology.
In embryology, mesoblast specifically refers to the middle germ layer that originates between the ectoderm and endoderm during early embryonic development. This layer gives rise to various important structures including bones, muscles, connective tissues, blood vessels, heart, and kidneys. It serves as the foundation for the development of the mesodermal tissues throughout the body.
Furthermore, mesoblast can also denote the actively dividing cells found in this middle layer during embryonic stages. These cells are pluripotent, meaning they have the capability to differentiate into various types of cells and tissues. The mesoblast cells play a crucial role in the formation of the body plan and the differentiation of specialized organs and systems.
In certain organisms, such as insects, mesoblast can refer to the mesoderm, which is one of the three primary germ layers. The mesoblast in these organisms is responsible for giving rise to muscle tissues, the reproductive system, and the excretory system.
Overall, mesoblast is an essential developmental term that describes the middle layer of cells in embryos and certain organisms, playing a vital role in the formation of various tissues and organs.
-
The middle germinal layer of the embryo, lying between the hypoblast and the epiblast and derived from the endoderm and ectoderm. The greater part of the body (skin, connective tissue, bone, muscle, and excretory organs) is derived from the mesoblast.

Etymology of MESOBLAST
The word "mesoblast" is derived from two Greek roots: "meso" meaning "middle" or "intermediate", and "blastos" meaning "germ" or "embryo".
In the context of embryology, the word "mesoblast" refers to the middle germ layer of cells that develops during embryonic formation to give rise to various structures in the body, including the musculoskeletal system, circulatory system, and connective tissues. It is a critical stage in early development, where the mesoblast differentiates into different cell types to form these structures.
The term was coined by the German anatomist and embryologist Karl Ernst von Baer (1792-1876), who made significant contributions to the field of embryology and was known for his detailed studies on the development of embryos across different species.
