Mesenchyme vs. Mesoderm: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 11, 2023
Mesenchyme is a type of embryonic connective tissue, whereas mesoderm is a middle layer of embryonic cells from which mesenchyme and other tissues develop.
Key Differences
Mesenchyme comprises loosely organized, undifferentiated cells that can develop into various types of connective tissues. While, mesoderm, a primary germ layer in early embryonic development, gives rise to mesenchyme and other structures like muscles and circulatory systems.
Mesenchyme is known for its role in forming the skeleton and other connective tissues. However, mesoderm contributes to the formation of not just connective tissues but also systems such as the cardiovascular, muscular, and urinary systems.
The cells in mesenchyme are multipotent, capable of differentiating into a variety of cell types. In contrast, the mesoderm is a more extensive layer that forms various specialized tissues and organs in the body.
Mesenchyme is characterized by its extracellular matrix and ability to migrate during development. Mesoderm is characterized by its position between the ectoderm and endoderm in the embryo and its role in segmenting the body plan.
Mesenchyme plays a critical role in the healing and repair of tissues due to its ability to differentiate. The mesoderm is essential in the initial formation and organization of the embryo's body structure.

Mesenchyme
The part of the embryonic mesoderm, consisting of loosely packed, unspecialized cells set in a gelatinous ground substance, from which connective tissue, bone, cartilage, and the circulatory and lymphatic systems develop.
Mesoderm
The middle embryonic germ layer, lying between the ectoderm and the endoderm, from which connective tissue, muscle, bone, and the urogenital and circulatory systems develop.
Mesenchyme
(anatomy) That part of the mesoderm of an embryo that develops into connective tissue, bone, cartilage, etc
Mesoderm
(embryology) One of the three tissue layers in the embryo of a metazoan animal. Through embryonic development, it will produce many internal organs of the adult, e.g. muscles, spine and circulatory system.
