From: Human fetal mesenchymal stem cell secretome enhances bone consolidation in distraction osteogenesis
Histological analysis showed that the secretome intervention accelerated new callus consolidation. a Representative sections stained with Trichrome Goldner showing better quality callus formation in the secretome group than in the other two groups. b Von Kossa staining clearly showed that most of the new bone has been consolidated and the continuity of the cortical bone and bone marrow cavities was evident in the secretome group at week 6. hFMSC human fetal mesenchymal stem cell, PBS phosphate-buffered saline
