Dead feeder cells support stem cell growth

Stem cells naturally cling to feeder cells as they grow in petri dishes. Scientists have thought for years that this attachment occurs because feeder cells serve as a support system, providing stems cells with essential nutrients.

DNA nanorobots target HER2-positive breast cancer cells

According to the Mayo Clinic, about 20% of breast cancers make abnormally high levels of a protein called human epidermal growth factor receptor 2 (HER2). When displayed on the surface of cancer cells, this signaling protein ...

Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...

Three-Dimensional Cell Culture: Making Cells Feel Right at Home

A team of Houston scientists has unveiled a new technique that uses magnetic nanobeads to levitate cells, allowing them to grow into three-dimensional structures. This technological leap from the flat Petri dish has the potential ...

Toenail fungus gives up sex to infect human hosts

The fungus that causes athlete's foot and other skin and toenail infections may have lost its ability to sexually reproduce as it adapted to grow on its human hosts.
