In what will soon be commonplace in drug research, scientists have used an artificial-intelligence algorithmic program to identify a compound, currently used in antimalarial treatment, that can effectively reverse the bone deterioration of osteoporosis.
-
Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer, and has the potential to provide individualized repairs to brain injuries.
-
Scientists at Stanford Medicine have tested a new potential treatment for Alzheimer’s disease in mice. The therapy involves transplanting blood stem cells from healthy mice into those with the disease, which helps replace defective neural cells.
-
Researchers created an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of embryonic development that may provide answers about birth defects and infertility.

In a world first, Budapest Zoo gorilla Liesel has received stem-cell therapy for her arthritis. It's hoped that this groundbreaking procedure, which aims to rejuvenate her damaged joint cartilage, will not just help her but be adapted for human use too.
-
In a phase 1 clinical trial, scientists have demonstrated that corneal transplants, grown from a patient’s own stem cells, can successfully restore some vision after an eye injury.
-
We can’t regenerate damaged tooth enamel, but scientists have now grown mini teeth in the lab that secrete enamel-producing proteins. This could be the first step towards “living fillings” that patch up cavities, or even lab-grown replacement teeth.
-
Researchers have used neonatal stem cells taken from heart tissue discarded after surgery to reduce bowel inflammation and promote healing, offering a new and alternative treatment to chronic inflammatory conditions like Crohn’s disease.
-
A new stem cell therapy for Parkinson’s disease, in which the donor would also become the transplant recipient, is one step closer to human trials after scientists were able to successfully grow and rebuild neurons in an animal model.
-
Scientists have created models of human embryos by programming stem cells. The models give a glimpse into a key stage of development that can reveal new insights into genetic disorders and preventing failure in early pregnancy.
-
Researchers have used a pair of drugs to stimulate pancreatic stem cells to grow into insulin-producing cells. The study’s findings could one day lead to an alternative way of restoring insulin production in people with type 1 diabetes.
-
Researchers have transplanted precursor stem cells into the damaged heart muscle of pigs, repairing injured cells and improving heart function. The study may lead to a treatment that can regenerate heart muscle damaged by a lack of oxygen.
