Stem cells in the skin remember an injury, helping them close recurring wounds faster, researchers have found. The discovery could advance research and treatment of psoriasis and other inflammatory diseases.

The F.D.A. has taken an industry-friendly approach toward companies using unproven cell cocktails to treat people desperate for relief from aging or damaged joints.

A new study supports launch of Phase I clinical trial to test a designer DNA agent -- an antisense oligonucleotide that targets a gene called IRF4 -- in patients with multiple myeloma.

Two stem cell researchers 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. The team, who used single cell cloning of lung stem cells to make their discovery, is now targeting the cells for new therapeutics.

A new study shows that lung stem cell secretions -- specifically exosomes and secretomes -- delivered via nebulizer, can help repair lung injuries due to multiple types of pulmonary fibrosis in mice and rats.

A drug used in stem cell therapy to treat certain cancers may also protect against cigarette smoke-induced lung injury.

Researchers found that Langerhans cells (LCs) play a crucial role in mucocutaneous acute guest-versus-host disease (aGVHD). Their experiments in mice showed that when the LCs of a recipient were depleted, the formation of mucocutaneous lesions was enhanced because the infiltration of CD8+ T cells was inhibited. Their findings have significant implications for improving blood stem cell transplantation treatments and clinical outcomes for patients.

Researchers have shown by in vitro experimentation that changes of glycans in mouse epidermal stem cells may serve as a biomarker of aging. Further, by overexpression of specific glycogenes in mouse keratinocytes, they replicated the glycome profile of aging cells as well as their decreased proliferation ability. These findings hold promise for stem cell research into skin disorders, specifically senile degeneration, wound healing and skin cancer.
