Dr. Magdalena Zernicka-Goetz: Photo courtesy Caltech Human embryonic stem cells (hESCs) have many remarkable properties, not the least of which is their ability to turn into every other kind of cell in our body. But there are limits to what researchers can do with embryonic stem cells. One issue is that there aren’t always hESCs … Continue reading Building embryo-like cells in the lab

Gene therapy is life-changing for children with a life-threatening brain disorder
If you have never heard of AADC deficiency count yourself lucky. It’s a rare, incurable condition that affects only around 135 children worldwide but it’s impact on those children and their families is devastating. The children can’t speak, can’t feed themselves or hold up their head, they have severe mood swings and often suffer from … Continue reading Gene therapy is life-changing for children with a life-threatening brain disorder
Stem cell gene therapy for Fabry disease shows positive results in patients

Stem cells used to promote quick and precise bone healing
A close-up view of the intricate microarchitecture of the pluripotent stem-cell-derived extracellular matrix. Image Credit: Carl Gregory/Texas A&M Although some broken bones can be mended with the help of a cast, others require more complex treatments. Bone grafts, which can come from the patient's own body or a donor, are used to transplant bone tissue … Continue reading Stem cells used to promote quick and precise bone healing
Boosting the blood system after life-saving therapy
Following radiation, the bone marrow shows nearly complete loss of blood cells in mice (left). Mice treated with the PTP-sigma inhibitor displayed rapid recovery of blood cells (purple, right): Photo Courtesy UCLA Chemotherapy and radiation are two of the front-line weapons in treating cancer. They can be effective, even life-saving, but they can also be … Continue reading Boosting the blood system after life-saving therapy
HIV eliminated from mice using CRISPR and LASER ART
Dr. Kamel Khalili In the United States alone, there are approximately 1.1 million people living with Human immunodeficiency virus (HIV), a virus that weakens the immune system by destroying important cells that fight off disease and infection. This number is much larger on a global scale, with 36.9 million people living with HIV as of … Continue reading HIV eliminated from mice using CRISPR and LASER ART
Muscle stem cells provide insight into treatment of muscular dystrophies and aging muscles
Dr. Alessandra Sacco, associate professor in the Development, Aging and Regeneration Program at Sanford Burnham Prebys. Muscles are a vital part of the body that enable us to walk, run, lift, and do everyday activities. When muscles start to deteriorate, we start to have difficulty performing these activities, which severely limits quality of life and … Continue reading Muscle stem cells provide insight into treatment of muscular dystrophies and aging muscles
Targeted treatment for pediatric brain tumors shows promising results
Image of medulloblastoma Imagine sitting in the doctor's office and being told the heartbreaking news that your child has been diagnosed with a malignant brain tumor. As one might expect, the doctor states that the most effective treatment option is typically a combination of chemotherapy and radiation. However, the doctor reveals that there are additional … Continue reading Targeted treatment for pediatric brain tumors shows promising results
Stories that Caught Our Eye: New ways to heal old bones; and keeping track of cells once they are inside you
How Youth Factor Can Help Repair Old Bones As we get older things that used to heal quickly tend to take a little longer to get better. In some cases, a lot longer. Take bones for example. A fracture in someone who is in their 70’s often doesn’t heal as quickly, or completely, as in … Continue reading Stories that Caught Our Eye: New ways to heal old bones; and keeping track of cells once they are inside you
For the first time, scientists entirely reprogram human skin cells to iPSCs using CRISPR
Back in 2012, Shinya Yamanaka was awarded the Nobel Prize in Physiology or Medicine for his group’s identification of “Yamanaka Factors,” a group of genes that are capable of turning ordinary skin cells into induced pluripotentent stem cells (iPSCs) which have the ability to become any type of cell within the body. Discovery of iPSCs … Continue reading For the first time, scientists entirely reprogram human skin cells to iPSCs using CRISPR
