A MSCs exhibited a flat fibroblast-like morphology. B Chloromethylbenzamido dialkylcarbocyanine-labeled MSCs emitted red fluorescence. C Cultured MSCs were analyzed using flow cytometry and anti-CD90, anti-CD44, anti-CD29, anti-CD34, and anti-CD45 antibodies. MSC mesenchymal stem cellBack to article page
