Interstitial serum albumin empowers osteosarcoma cells with FAIM2 transcription to obtain viability via dedifferentiation

During hematogenous metastasis, cancer cells escape from primary lesions and enter into the circulatory system, and only a few can colonize distant organs. However, the mechanism of cell survival and metastasis in the hematopoietic environment remains unclear. Angiorrhea is the character of pathological neovascularization in malignant tumors and commonly detected in osteosarcoma (OS), a bone tumor that prefers circulatory metastasis. In the...
