Abstract

Hypoxia is an important factor that results in failure of chemotherapy for the majority of solid tumor types, particularly for gastric cancer. In the present study, mesenchymal stem cells (MSCs), which have the ability to migrate to cancer tissues were used as a vehicle to supply oxygen to gastric cancer. The hemoglobin genes were transfected into MSCs as MSC‑hemo groups. Subsequently, MSC‑hemo groups were induced by isopropyl‑b‑D‑thiogalactopyranoside and hemin to express hemoglobin. The hemoglobin was detected by western blotting method. Following this, the MSC‑hemo groups were placed in an atmosphere containing 100% oxygen and were used to investigate the effect of the function of the oxygen‑laden MSC‑hemo group on gastric cancer chemotherapy with an MTT assay. As a first approach to investigate the possibility of MSCs as a vehicle to supply oxygen to anoxic cancer types, including gastric, liver, breast cancer, the results indicated that the oxygen‑laden MSC‑hemo group significantly enhanced the effect of chemotherapeutic treatments on gastric cancer cells. Utilizing MSCs as a svehicle to supply oxygen to the solid tumor may be a novel method to improve the hypoxia conditions of tumor tissues and improve the effect of chemotherapy on tumor cells.
