Chemically defined medium for human mesenchymal stem cells
First Claim
1. A method for culturally expanding human mesenchymal stem cells comprising culturing an isolated homogenous population of viable human mesenchymal stem cells for a suitable time in a serum free medium which comprises (1) a minimum essential medium;
- (2) serum albumin;
(3) an iron source;
(4) insulin or an insulin-like growth factor;
(5) glutamine; and
(6) a mitogen selected from the group consisting of platelet derived growth factor and serotonin, which are present in amounts effective to culturally expand the human mesenchymal stem cells.

Abstract
A composition and method for maintaining the viability of human mesenchymal precursor cells in a serum-free environment which composition includes (1) a minimum essential medium; (2) serum albumin; (3) an iron source; (4) insulin or an insulin-like growth factor; and (5) at least one amino acid selected from the group consisting of glutamine, arginine and and cysteine, and is free of serum. Also, a composition and method for culture expanding human mesenchymal precursor cells in a serum-free environment. This composition further includes a mitogen, paricularly a serotonergic agonist. The cells are preferably isolated human mesenchymal stem cells.
