Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
Primary mesenchyme is the first embryonic mesenchymal tissue to emerge, and it is produced from EMT in epiblast cells. In the epiblast , it is induced by the primitive streak through Wnt signaling , and produces endoderm and mesoderm from a transitory tissue called mesendoderm during the process of gastrulation .

The cell surface antigens most commonly used to identify hES cells are the glycolipids stage specific embryonic antigen 3 and 4, and the keratan sulfate antigens Tra-1-60 and Tra-1-81. The molecular definition of a stem cell includes many more proteins and continues to be a topic of research. [29]
A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [1] [2] Connective tissue is a broad term that includes bone, cartilage, muscle, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues.
Hematopoietic stem cells (adult stem cells) from the bone marrow that give rise to red blood cells, white blood cells, and platelets. Mesenchymal stem cells (adult stem cells) from the bone marrow that give rise to stromal cells, fat cells, and types of bone cells; Epithelial stem cells (progenitor cells) that give rise to the various types of ...
Mesenchymal (mesoderm origin) stem cells are undifferentiated, meaning they can differentiate into a variety of generative cells commonly known as osteochondrogenic (or osteogenic, chondrogenic, osteoprogenitor, etc.) cells.
The origin of the ectomesenchyme is disputed. It is either like the mesenchyme, arising from mesodermic cells , or conversely arising from neural crest cells . [ 1 ] The neural crest is a critical group of cells that form in the cranial region during early vertebrate development.
