Preeclampsia is the leading cause of death and disability, for both mothers and babies, killing approximately 76,000 mothers and 500,000 babies globally every year. Despite this, the only cure at present is to deliver the placenta and the baby, with the potential for long term complications.

Two stem cell experts have found an abundance of abnormal stem cells in the lungs of patients who suffer from Chronic Obstructive Pulmonary Disease (COPD), a leading cause of death worldwide. Frank McKeon, professor of biology and biochemistry and director of the Stem Cell Center, and Wa Xian, research associate professor at the center, used single cell cloning of lung stem cells to make their discovery. Now they are targeting the cells for new therapeutics.

Researchers have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly. Using the CRISPR/Cas9 gene editing, they have also managed to modify the cells so that they can hide from the immune system to prevent rejection.

Researchers show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumor innervation could thus lead to new cancer therapies.

Mayo Clinic researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a blueprint of how stem cells may work.

Parkinson’s disease researchers have used gene-editing tools to introduce the disorder’s most common genetic mutation into marmoset monkey stem cells and to successfully tamp down cellular chemistry that often goes awry in Parkinson’s patients.

Researchers of the Hubrecht Institute (KNAW — The Netherlands) and the Max Planck Institute in Münster (Germany) have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem cells. Their findings are published in the Biophysical Journal.

Recently, a type of biodegradable hydrogel, dubbed microporous annealed particle (MAP) hydrogel, has gained much attention for its potential to deliver stem cells for body tissue repair. But it is currently unclear how these jelly-like materials affect the growth of their precious cellular cargo, thereby limiting its use in regenerative medicine.

Scientists have developed a new TREE method (an acronym short for transient reporter for editing enrichment, or TREE), which allows for bulk enrichment of DNA base-edited cell populations — and for the first time, high efficiency in human stem cell lines.

Writing in the journal Stem Cells Translational Medicine, an international research team, led by physician-scientists at University of California San Diego School of Medicine, describe a new method for delivering neural precursor cells (NSCs) to spinal cord injuries in rats, reducing the risk of further injury and boosting the propagation of potentially reparative cells.
