Isolation and identification of mesenchymal stem cells from human lipoma tissue.
Lipoma is a benign neoplasm of normal fat cells that appears as a soft, movable swelling, often with a slight yellowish coloration. Human mesenchymal stem cells (MSCs) that have been isolated from bone marrow, blood, and other adult tissues including adipose tissue have the potential to be useful candidates for therapy. No literature had reported about stem cells from lipoma tissue. Here, a new cell culture method is described and utilized to greatly accelerate the growth rate and prolong the lifespan of lipoma-derived MSCs. Cells produced in early cultures display characteristics similar to those previously reported for multipotential stem cells, including a high frequency of anchorage-independent growth in soft agar and a lack of gap junctional intercellular communication in cell types with serpiginous morphology. These cells can differentiate into adipocytes, osteoblasts, and chondrocytes after induction. In conclusion, lipoma-derived stem cells possessing the characteristics of MSCs are described for the first time.
