[Generation and validation of inducible osteoblast-specific Stat3 knockout mice].

Based on the Cre-Loxp gene knockout system, this study intended to construct tamoxifen-inducible STAT3 conditional knockout mice and verify the knockout efficiency.The inducible osteoblasts-specific Stat3 knockout mice Stat3Col1ERT2 were obtained by hybridization through C57 mice of Stat3fl/fl and Col1 creERT2. Bone mesenchymal stem cells(BMSCs) of these mice were isolated and cultured with or without 4-hydroxytamoxin(4-OTH), to verify the...
