Can I expand the human Mesenchymal Stem Cells prior to differentiating them?

These cells are frozen at the end of 2^nd culture. Thawing and seeding results in passage 2 (3^rd culture). We recommend that they be used for differentiation experiments not later than passage 5. The differentiation potential of hMSC in vitro is reduced with ongoing population doublings; meaning the earlier differentiation is induced; the higher the differentiation rates.
