Scientists have made a breakthrough in stem cell research which raises the prospect of regrowing damaged sections of a person’s liver, pancreas or even their brain.
Researchers at the University of NSW have found a way to improve the lifespan and competitiveness of stem cells, overcoming a problem which otherwise saw their regenerative powers fade in about an hour.
Adult stem cells were given a gene to make them resistant to chemotherapy, handing them an “advantage” when used to treat damaged tissue in conjunction with the cancer-fighting treatment.

The drug metformin, a mainstay of diabetes care for 15 years, may have a new life as a cancer treatment, researchers said.
In a study in mice, low doses of the drug, combined with a widely used chemotherapy called doxorubicin, shrank breast-cancer tumors and prevented their recurrence more effectively than chemotherapy alone.
The findings add to a growing body of evidence that metformin, marketed as Glugophase by Bristol-Myers Squibb Co. and available in generic versions, could be a potent antitumor medicine.
They also lend support to an emerging theory that cancer’s ability to survive and resist therapy is regulated by cancer stem

Plerixafor has allowed doctors to collect stem cells from patients where there had been previous difficulties.
The drug, which has only recently been licensed, is being used at the Beatson West of Scotland Cancer Centre.
Stem cells therapies are used to treat people with cancer of the blood. The cells are collected and reintroduced to a patient after chemotherapy.
Doctors often encounter problems collecting enough stem cells from about one in 10 cancer patients to undergo treatment.
Plerixafor has, so far, had a 100% success rate in allowing doctors at the cancer centre to collect enough cells from patients who fall
Experimenting with cells in culture, researchers at the Johns Hopkins Kimmel Cancer Center have breathed possible new life into two drugs once considered too toxic for human cancer treatment. The drugs, azacitidine (AZA) and decitabine (DAC), are epigenetic-targeted drugs and work to correct cancer-causing alterations that modify DNA.
The researchers said that the drugs also were found to take aim at a small but dangerous subpopulation of self-renewing cells, sometimes referred to as cancer stem cells, which evade most cancer drugs and cause recurrence and spread.

A 3-year-old South Dakota boy whose brain tumor treatment had been in question because of an insurance dispute is set to begin chemotherapy in Minnesota this week.
Cooper Urbaniak, who suffers from ependymoma, is to be admitted to the University of Minnesota Medical Center Tuesday to begin high-dose chemotherapy and a stem cell transplant.
The family’s insurance provider initially declared the procedure experimental and refused to pay for it. But under an agreement reached last month between Sanford Health Plan and the university, Sanford will pay for the chemotherapy and pay a discounted rate on the stem cell transplant.
