Heparin is a common cell culture adjuvant for the expansion of human stem cells.
Heparin affects multiple cell signaling components that can alter human mesenchymal stem cell responsiveness.
Heparin exerts donor-dependent effects on gene expression and proliferation of human mesenchymal stem cells.
Heparin is contra-indicated as a culture supplement for the expansion and maintenance of naïve human mesenchymal stem cells.
