histochemical staining revealed that differentiating odontoblasts and osteoblasts exhibited alkaline phosphatase activity at stages prior to appearance of gla proteins and that cells adjacent to odontoblasts and osteoblasts ( not directly involved in the formation of predentin/dentin and osteoid/bone ) stained for alkaline phosphatase , but not for gla proteins .
