USC study paves path to a cure for chronic HBV infection

The infection has been cured in mice by removing “traitors” residing in liver’s immune cells. Chronic hepatitis B infection, a lifetime disease with no effective cure, could one day be cleared from a person’s system with a series of shots, according to a new USC study. Most healthy adults infected with HBV will develop protective

USC Stem Cell scientists enter the conversation about CRISPR

CRISPR-Cas9 is a gene-editing technique that enables scientists to disable, replace or modify sections of DNA. It allows for unprecedented precision and speed in the field of genome editing. It has been used to create micropigs to be sold as pets and to try to eradicate HIV infection in humans. The scientific community is concerned about altering human embryos to

USC Stem Cell study illuminates bone formation and vertebrate evolution

With the emergence of bone, the diversity of life expanded to encompass the bone-forming vertebrates, a group of species ranging from the tiny frog Paedophryne amauensis to the mighty blue whale. Bone formation in vertebrates is linked to a shared gene, called Sp7 or Osterix, that acts early in establishing the bone-forming cells or osteoblasts.
