PANCREATIC CANCER TUMORS DEFEATED WITH CORD BLOOD STEM CELLS

What happens when you “genetically engineer MSCs isolated from human umbilical cord blood so that they expressed IL-15” (which fights cancer tumors) and inject them into mice with pancreatic  tumors?

  • The IL-15 migrate to the tumor
  • Other cancer and tumor fighting immune cells migrate to the tumor
  • The IL-15 attack the tumor
  • Other cancer and tumor fighting immune cells attack the tumor
  • Tumors show cell death
  • Tumor growth is significantly inhibited
  • Survival is prolonged
  • The mice immune systems are effectively vaccinated against future tumor growth

Scientists “used these souped-up cells to treat In mice afflicted with pancreatic tumors. Pancreatic cancer is an indiscriminate killer, since by the time it causes any symptoms, it is usually so advanced, that there is little to be done in order to treat it. Thus new strategies to treat this type of cancer are eagerly being sought. Systemic administration of IL-15-expressing MSCs significantly inhibited tumor growth and prolonged the survival of tumor-bearing mice. The tumors of these mice showed extensive cell death, and other types of immune cells known to fight tumor cells (NK and T cells) had also accumulated around the tumor. Other experiments confirmed that the injected MSCs did indeed migrate toward the tumors and secrete IL-15 at the site of the tumors…Interestingly, those mice that were cured from the pancreatic tumors, appeared to have a kind of resistance of these tumors. Namely, when Fan and his colleagues tried to reintroduce the same tumor cells back into the cured mice, the tumor cells would not grow. Thus the engineered MSCs not only tuned the immune system against the tumor, but they effectively vaccinated the mice against it as well.”
