Systemic effects of starved fibroblast culture supernatant on immunosuppressed rats treated with cancer stem cells (LA7).

Background: The present study aimed to investigate and compare the effect of starved fibroblast culture supernatant (SFS), DMEM and normal saline alone or along with LA7 on dexamethasone-treated immunosuppressed Wistar rats.

Methods: After the isolation of fibroblasts from the fresh foreskin of children, it was cultured in serum-free DMEM, and the supernatant collected after 16 hours (16h-SFS). This solution and the other treatments were injected subcutaneously into the rats from each group once daily for 14 days.
