A lipoblast is a precursor cell for an adipocyte. [1] Alternate terms include adipoblast [ 2 ] and preadipocyte . [ 3 ] Early stages are almost indistinguishable from fibroblasts .
Mesenchymal stem cells can differentiate into adipocytes, connective tissue, muscle or bone. [ 1 ] The precursor of the adult cell is termed a lipoblast , and a tumor of this cell type is known as a lipoblastoma .
Adipogenesis is a tightly regulated cellular differentiation process, in which mesenchymal stem cells committing to preadipocytes and preadipocytes differentiating into adipocytes. Cellular differentiation is a change of gene expression patterns which multipotent gene expression alters to cell type specific gene expression.

Osteochondroprogenitor cells are progenitor cells that arise from mesenchymal stem cells (MSC) in the bone marrow. They have the ability to differentiate into osteoblasts or chondrocytes depending on the signalling molecules they are exposed to, giving rise to either bone or cartilage respectively.
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 .
In mesenchymal stem cell therapy, most of the cells are extracted from the adult patient's bone marrow [2] [3] Mesenchymal stem cells can be obtained via a procedure called bone marrow aspiration. A needle is inserted into the back of the patients hip bone and cells are removed to be grown under controlled in vitro conditions in a lab.
