Fig. 1From: Periostin promotes the proliferation and metastasis of osteosarcoma by increasing cell survival and activates the PI3K/Akt pathwayExpression of POSTN is greater in OS than normal bone cells. A qRT-PCR of POSTN in normal (C-28) and OS (MG-63, Saos-2, and I2-OS) bone cells (P < 0.0001). B Western blotting of POSTN in normal (C-28) and OS (MG-63 and Saos-2) bone cells (P = 0.007, P = 0.009). C Western blotting of POSTN in normal and OS bone tissues (P = 0.0014, n = 4). D Hematoxylin–eosin staining and immunohistochemical staining of POSTN in paraffin sections of normal and OS tumor tissuesBack to article page
