Researchers at La Jolla Institute for Immunology (LJI) have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants. Their new study, published online on July 1, 2021 in Cell Reports Medicine, shows that both CD4+ “helper” T… Read More »
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 »
Ana Martin-Villalba and her research team at the German Cancer Research Center followed stem cells along the path to neurons. The scientists analyzed at every step which genes where switched on and which of them were actually turned into new proteins. They expected to find that stem cells would simply switch their stem cell genes… Read More »
A drug to fight aging may finally be on the horizon after the first trials in humans showed “impressive” results. For many years, scientists have known that an accumulation of senescent cells in the body is linked to aging symptoms such as frailty and arthritis, as well as diseases such as Alzheimer’s and Parkinson’s. Senescent… Read More »
Stem cells (so-called “master cells”) are unique and important in the body because they can do almost anything, and scientists have only begun to discover their potential. That’s why researchers’ use of them has created controversy, attracting the attention of scientists, policymakers, and bioethicists across the globe. Stem cells can transform into any of the… Read More »
