With CRISPR, Modeling Disease in Mini Organs

May 6, 2016 | Categories: Research | Tagged: , , , ,

Traditionally, gene therapy efforts have attempted to treat genetic diseases by modifying DNA inside a patient’s body, but it has been a challenge to deliver the genetic material to all the target tissue, let alone to do so safely. But in recent years, advances in gene editing and stem cell research have enabled scientists to […] Read More

Students help conduct intensive, real-world research at UW Medicine lab UW undergraduate Randy Lu grasps a pair of tweezers in each hand. His fingers make imperceptible movements as he dissects the tiny abdomen of a fruit fly. The tweezers and Lu’s hands look garishly large next to the insect, which is a mere speck in […] Read More

Mini-kidney organoids re-create disease in lab dishes

October 23, 2015 | Categories: Research | Tagged: , , , ,

Stem-cell biology and gene editing advances offer hope for kidney regeneration, drug discovery Mini-kidney organoids that re-create human kidney disease have now been grown in laboratory petri dishes. The achievement, believed to be the first of its kind, resulted from combining stem cell biology with leading-edge gene-editing techniques.  The journal Nature Communications reports the findings […] Read More

Dying cells can protect their stem cells from destruction

May 11, 2015 | Categories: Research | Tagged: , ,

An SOS signal from dying daughter cells allows their mother stem cells to protect themselves from radiation and chemotherapy damage Cells dying as the result of radiation exposure or chemotherapy can send a warning to nearby stem cells. The chemical signal allows the stem cells to escape the same fate, University of Washington researchers report […] Read More

Injection of marrow stem cells into the heart is proven ineffective

April 21, 2015 | Categories: Research | Tagged: , ,

Marrow stem cells were injected into failing hearts of 6 patients awaiting transplantation A small study by University of Washington researchers has found no sign that bone-marrow stem-cell injections stimulated repair in the damaged hearts of patients awaiting transplantation. The results were published in the Journal of the American Academy of Cardiology. Dr. April Stempien-Otero, UW associate professor of […] Read More
