Stem cells show much promise, both for testing drugs and for treating disease. But the hype around them has been dangerous, as most treatments are in very experimental stages and can cause harm.
The idea behind regenerative medicine is that the patient is both the donor and recipient of healthy tissue grown from stem cells. But sometimes the transplanted cells are rejected. Now we know why.
Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.
Headlines around the world declared that a second person was cured of their HIV. But while the results are encouraging, we're a long way from a cure.
Dangerous open wounds known as cutaneous ulcers are common in people with diabetes and bedsores. Now scientists have figured out how to reprogram the cells inside these wounds to heal themselves.
A large trial to test whether rebooting the immune system will help patients with Crohn's disease has just begun.
Figuring out what causes diseases like autism, schizophrenia and depression is tricky. Now Stanford University researchers are turning blood into brain cells to study these diseases in a dish.
'Mini brains' can be grown in the lab, and brains of decapitated pigs were recently 'kept alive' for a day and a half. But what makes a conscious brain?
The nomination deadline for science's most lucrative prize -- the Breakthrough Prize -- is looming. Why has no Canadian ever received this prize, despite groundbreaking discoveries?
An increasing list of rare diseases can now be treated with gene therapy. But we need to figure out a way to make them affordable.
Neuroscience labs around the world may need to reevaluate some of their assumptions about whether what works in animals will really produce meaningful treatments for people.
Stem cell treatments for eye disease always seem to be just on the horizon, but real progress is being made.
All multiple sclerosis sufferers have stem cells with the potential to heal them, but scientists are only just figuring out how to kick them into action.
Mutated bone marrow stem cells could double your risk of having a heart attack.
New research suggests life on Earth became more diverse because of a change in biology related to stem cells, not just rising oxygen levels.
As people's bodies age, so do their blood cells. This affects immunity and an ability to withstand certain cancer treatments. A recent study in mice suggests that those cells can be rejuvenated.
New mouse model study sheds light on why alcohol is so harmful.
Only one Canadian has ever received the Nobel Prize for medicine, in 1923. But Canadian discoveries have been essential to stem cell research, gene sequencing and treatments for cancer.
After much lobbying, the TGA has announced it will crack down on dodgy stem cell clinics.
Stem cell science continues to offer great promise. But a growing number of clinics are selling treatments without evidence that what they offer is effective – or even safe.
