You may use the murine calvarial pre-osteoblast cell line MC3T3-E1 which has been established from a C57BL/6 mouse calvaria and has a high alkaline phosphatase (ALP) activity in the resting state. These cells have the capacity to differentiate into osteoblasts and osteocytes and have been demonstrated to form calcified bone tissue in vitro.
Regarding the protocol to establish diabetic condition in pre-osteoblast cell culture, you may want to refer to the article attached below. It will be helpful!
