Bone formation in the human body is divided into intramembranous and endochondral ossification. The skull base bones are formed
by enchondral ossification while the calvarium and facial bones are intramembranous ossification. The suture line is the center
for intramembranous bone formation. In order to continue the growth of the skull, the middle section of this center must remain
unossified and opposite edges of sutures must allow the formation of new bone by the osteoblasts. The tissues that interact with
each other in the cranial suture complex to provide suture regulation are; dura mater, osteogenic edges of calvarial bone plates,
mesenchymal tissue of cranial sac, and pericranium. Molecular regulation of suture growth and closure is achieved by interaction
of transcription factors, cytokines, growth factor receptors and extracellular matrix molecules.
