Perivascular mesenchymal precursor cells
First Claim
1. A therapeutic composition comprising a suspension of culture expanded mammalian mesenchymal precursor cells (MPCs), wherein the culture expanded cells are derived from adipose tissue cells that are multipotent and at least 1% of the culture expanded cells are positive for the surface marker 3G5 and one or both of the surface markers MUC18/CD146 and STRO-1.

Abstract
Mesenchymal precursors cells have been isolated from perivascular niches from a range of tissues utilizing a perivascular marker. A new mesenchymal precursor cell phenotype is described characterized by the presence of the perivascular marker 3G5, and preferably also alpha smooth muscle actin together with early developmental markers such as MUC 18, VCAM-1 and STRO-1bri. The perivascular mesenchymal precursor cell is multipotential and is shown to form, vascular tissue, as well as bone marrow dentin and pulp. A method of enriching using cell sorting based on these markers is also described.
