Development of New Stem Cell Type May Lead to Advances in Regenerative Medicine

A team has derived a new 'intermediate' embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm ...

World's First: Drug Guides Stem Cells to Desired Location, Improving Their Ability to Heal

Scientists have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy -- a scientific first and major advance for ...

Survey Finds American Support for Human-Animal Chimera Research

In September 2015, the US National Institutes of Health placed a funding moratorium on research that involves introducing human pluripotent stem cells into animal embryos. To assess attitudes on ...

CRISPR Tagging Improves Accuracy of Model Cells Grown from Stem Cells

CRISPR tags are being used to identify all of the transcription factors necessary to turn a pluripotent stem cell into a suitable adult cell for research, and possible future cell therapies. An ...

The Natural Artistry of Disease: A Wintry Landscape in the Eye

Researchers report a case of frosted branch angiitis in a woman presenting years after being treated for leukemia-lymphoma with allogeneic human stem cell transplant. The relevance of this ocular ...

Langerhans Cells Are Up to the Job, They Just Need a Chance

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 ...

How Herpes Infection May Impair Human Fetal Brain Development

Three cell-based models shed light on how herpes simplex virus type 1 (HSV-1) infection, which can spread to the fetal brain during pregnancy, may contribute to various neurodevelopmental ...

Delivering Proteins to Testes Could Someday Treat Male Infertility

According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, ...

Researchers Make Counterintuitive Discoveries About Immune-Like Characteristics of Cells

Biologists reveal that tissue perturbations by chemotherapy agents promote stem cell expansion and that fibroblast cells exhibit unexpected, immune-like ...

To Make Mini-Organs Grow Faster, Give Them a Squeeze

To make organoids grow faster, give them a squeeze, suggests a new study, which finds compressing cells, and crowding their contents, can coax them to grow and divide. The results may lead to faster ...

Hair Loss Might Be Prevented by Regulating Stem Cell Metabolism

Medical researchers have identified a mechanism that is likely to prevent hair ...

Skeletal Muscle Development and Regeneration Mechanisms Vary by Gender

Researchers have generated mice lacking the estrogen receptor beta gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal ...

Damaged Muscles Don't Just Die, They Regenerate Themselves

Researchers building a model of muscle damage in a cultured system found that components leaking from broken muscle fibers activate ''satellite cells,'' which are muscle stem ...

Stem Cell Sheets Harvested in Just Two Days

A team has developed a thermoresponsive nanotopography cell culture ...

A Small Switch With a Big Impact

Minor changes in immune cells can significantly affect the immune response, scientists have now discovered. Their findings could be relevant for stem cell ...

Coupling Antibiotics With Stem Cells to Fight Off Bone Infections

Researchers investigated the effects of adipose-derived stem cells (ADSCs) loaded with the antibiotic ciprofloxacin on osteomyelitis caused by implants. By administering ADSC-loaded ciprofloxacin to ...

Researchers Demonstrate How Changing the Stem Cell Response to Inflammation May Reverse Periodontal Disease

Scientists have discovered that a specific type of molecule may stimulate stem cells to regenerate, reversing the inflammation caused by periodontal ...

Autoimmune Disease: UM171 Saves Another Life

A recently developed UM171 molecule was used in a blood transplant by a medical team on a young man suffering from severe aplastic anemia, an autoimmune ...

Exosome Treatment Improves Recovery from Heart Attacks in a Preclinical Study

Research in pigs shows that using the exosomes naturally produced from a mixture of heart muscle cells, endothelial cells and smooth muscle cells -- which were all derived from human induced ...

Fine-Tuning Stem Cell Metabolism Prevents Hair Loss

An international research team has shown in mice that Rictor, a protein that helps to regulate the growth, energy, and oxygen consumption of cells, plays a key role in the cellular metabolism and ...

Stem Cells Can Repair Parkinson's-Damaged Circuits in Mouse Brains

Researchers demonstrated a proof-of-concept stem cell treatment in a mouse model of Parkinson's disease. They found that neurons derived from stem cells can integrate well into the correct ...

Placenta Is Initiated First, as Cells of a Fertilized Egg Divide and Specialize

The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, ...

Hormone That Might Help Treat Malabsorption Identified

Scientists at Cincinnati Children's used human intestinal organoids grown from stem cells to discover how our bodies control the absorption of nutrients from the food we eat. They further found ...
