Mesenchymal Stem Cells, or MSCs, are found in a variety of tissues, such as bone marrow and fat. These cells are defined by their ability to adhere to plastic and to differentiate into cartilage, fat, and bone. At Ossium, we purify MSCs from bone marrow.  The MSCs are then cultured and banked. Ossium MSCs are available at Passage 2 and Passage 4.

Hematopoietic Stem Cells, or HSCs, are the source of all other human blood and immune cells. HSCs are capable of self-renewal, replicating to replace themselves, as well as differentiation, which occurs when they become cells with more specialized functions. Ossium purifies HSCs from bone marrow by selecting for cells that express a protein called CD34. This marker is the industry standard method for selecting HSCs and is how we refer to our cells.
