hES-MP 002.5 cells are human embryonic stem (ES) cell-derived multipotent mesenchymal progenitors that resemble adult human mesenchymal stem (MS) cells and can be differentiated into several mesodermal lineages. The cells are derived from the SA002.5 ES cell line, a subclone of SA002, known for efficient osteogenic lineage differentiation and high mineralization potentialwith extended culture. hES-MP 002.5 cells are a homogeneous, robust source of mesenchymal progenitors, ideal for bulk production of mesenchymal cells.
