Despite the huge body of research on osteogenic differentiation and bone tissue engineering, the translation potential of in vitro results still does not match the effort employed. One reason might be that the protocols used for in vitro research have inherent pitfalls. The synthetic glucocorticoid dexamethasone is commonly used in protocols for trilineage differentiation of human bone marrow...

Phosphoproteomic profiling reveals a defined genetic program for osteoblastic lineage commitment of human bone marrow–derived stromal stem cells

Barrio-Hernandez, Inigo ; Jafari, Abbas ; Rigbolt, Kristoffer T.G. ; Hallenborg, Philip ; Sanchez-Quiles, Virginia ; Skovrind, Ida ; Akimov, Vyacheslav ; Kratchmarova, Irina ; Dengjel, Jörn ; Kassem, Moustapha ; Blagoev, Blagoy

Bone marrow–derived mesenchymal stem cells (MSCs) differentiate into osteoblasts upon stimulation by signals present in their niche. Because the global signaling cascades involved in the early phases of MSCs osteoblast (OB) differentiation are not well-defined, we used quantitative mass spectrometry to delineate changes in human MSCs proteome and phosphoproteome during the first 24 h of...
