Mesenchymal differentiation assays of proliferating infantile hemangioma–derived primary cell lines demonstrating lipid droplets stained with Oil Red O in CD34+ (A, red, arrows) and CD34− (B, red, arrows) cellular fractions for adipogenesis relative to the 3T3 positive control (C, red, arrows), and calcium deposits stained with Alizarin Red in CD34+ (D, red, arrows) and CD34− (E, red, arrows) cellular fractions for osteogenesis relative to the 3T3 positive control (F, red, arrows).
