AKT1 and neoplasm: A large number of literature studies have indicated that MSCs can act as sensors between tumor cells and the microenvironment and they can be involved in immune suppression, stimulation of angiogenesis, inhibition of apoptosis of cancer cells, induction of epithelial-mesenchymal transformation, and other links to promote tumor growth [9–11], but some studies have shown that it can inhibit tumor growth by inhibiting angiogenesis, AKT signaling, and Wnt signaling pathway; but its role in the occurrence and development of osteosarcoma is still unknown [12, 13].
