post-mitotic: 12 week human fetus head double-stained to show newly formed cartilage (with alcian blue, in blue) and bone (with alizarin red, in purple) this technique highlights how the skull forms by two different mechanisms: intramembranous ossification and endochondral ossification endochondral ossification, which occurs in the endocranium (occipital, sphenoid, and ethmoid), begins with a cartilage model that is eventually replaced by bone bones of the cranial vault and face, on the other hand, form by the intramembranous route which involves the lacy growth of bone within loose mesenchymal tissue without a cartilage model for guidance light microscopy credit: University of South New Wales
