Dexamethasone has variable effects on mesenchymal stromal cells

A low dose of Dex favors MSC expansion in vitro, and protects against apoptosis. It is not suitable for MSC to be pre-treated with Dex when they are to be used to treat immunologic disease. However, when MSC are applied to promote angiogenesis, it is beneficial for them to be pre-treated with 10−9 mol/L Dex.
