“…Furthermore, EGF mediates osteogenic differentiation of dental pulp mesenchymal stem cells [ 83 ]. In vivo , EGF displayed a synergistic effect with human recombined BMP-2 (hrBMP-2) on bone formation in rat calvarial defects and in tibial defects of rabbits [ 84 , 85 ].…”

“…For example, EGF or EGF-like proteins together with other stimuli (i.e. BMP-2) may favour the first phases of fracture healing, which recapitulate endochondral bone development [ 84 , 85 ]. In particular, the use of AREG in combination with scaffolds may stimulate MSC migration, thus favouring osteogenesis in the early phases of nonunions [ 67 ].…”

Epidermal growth factor signalling pathway in endochondral ossification: an evidence-based narrative review

During endochondral bone development, a complex process that leads to the formation of the majority of skeletal elements, mesenchymal cells condense, differentiating into chondrocytes and producing the foetal growth plate. Chondrocytes progressively hypertrophy, induce angiogenesis and are then gradually replaced by bone. Epidermal Growth Factor (EGF), one of many growth factors, is the prototype of the EGF-ligand family, which comprises several proteins involved in cell proliferation, migration and survival. In bone, EGF pathway signalling finely tunes the first steps of chondrogenesis by maintaining mesenchymal cells in an undifferentiated stage, and by promoting hypertrophic cartilage replacement. Moreover, EGF signalling modulates bone homeostasis by stimulating osteoblast and osteoclast proliferation, and by regulating osteoblast differentiation under specific spatial and temporal conditions. This evidence-based narrative review describes the EGF pathway in bone metabolism and endochondral bone development. This comprehensive description may be useful in light of possible clinical applications in orthopaedic practice. A deeper knowledge of the role of EGF in bone may be useful in musculoskeletal conditions which may benefit from the modulation of this signalling pathway. Key messages The EGF pathway is involved in bone metabolism. EGF signalling is essential in the very early stages of limb development by maintaining cells in an undifferentiated stage. EGF pathway positively regulates chondrocyte proliferation, negatively modulates hypertrophy, and favours cartilage replacement by bone. EGF and EGF-like proteins finely tune the proliferation and differentiation of bone tissue cells, and they also regulate the initial phases of endochondral ossification.
