Human Sperm Stem Cells Grown in Lab, an Early Step Toward Infertility Treatment

Infertility affects one in seven men of reproductive age worldwide. One idea for treating male sterility is spermatogonial stem cell (SSC) therapy. In this approach, sperm stem cells in the testis are transferred to a test tube, cultured and nudged into becoming fully fledged sperm. However, a key bottleneck has been identifying just the right… Read More »

Mysterious tuft cells found to play role in pancreatitis

Persistent inflammation of the pancreas (chronic pancreatitis) is a known risk factor for developing pancreatic cancer, the third-deadliest cancer in the United States. Tuft cells — cells sensitive to chemical (chemosensory) changes typically found in the intestines and respiratory tract — had previously been discovered in the pancreas, but their function has largely remained a… Read More »

Tiny Traps Lure Cancer Cells for Diagnostics, Treatment Monitoring

Detecting cancer at its early stages remains a major challenge in oncology. Even monitoring the progression of cancer is difficult, but researchers at the University of Michigan have come up with a tiny implantable device that can draw cancer cells toward itself for gene expression analysis. The microscopic device is a biomaterial scaffold that is… Read More »

Light-activated metal catalyst destroys cancer cells’ vital energy source

A space-age metal that formed part of the asteroid that destroyed the dinosaurs could provide a new method of treating cancer tumours selectively using light. Scientists at the University of Warwick in collaboration with colleagues in China, France, Switzerland and Heriot-Watt University have developed a technique that uses light to activate a cancer-killing compound of… Read More »
