Overview

USC Stem Cell scientists are advancing our understanding of how the body develops, maintains and repairs the brain, nerves and senses. They are using stem cells to find new regenerative therapies for conditions including Alzheimer’s disease, neurodegenerative diseases, brain tumors, hearing loss and vision loss.

Statistics

  • Alzheimer’s disease is the sixth leading cause of death in the US. An estimated 5.5 million Americans are living with Alzheimer’s disease.
  • ALS, or Lou Gehrig’s disease, causes progressive paralysis and usually results in fatal respiratory failure within three to five years of diagnosis.
  • Brain tumors are the most common cancer and leading cause of cancer-related death in children fourteen years and younger.
  • Twenty percent of Americans—or 48 million people—report some degree of hearing loss.
  • More than 20 million Americans report some degree of vision loss.

In the zebrafish inner ear, a cell type known as supporting cells (magenta) gives rise to new sensory hearing cells (blue). The study reveals a set of DNA control elements critical for supporting cells to regenerate hair cells after injury in zebrafish, lizards and other regenerative species.

To remember conversations, keep making new brain cells

USC-led study of patients with epilepsy shows how making new neurons benefits cognition in adults. Why do adults make new brain cells? A new study published in Cell Stem Cell provides the …

A circular field of cells shows a gradient of patterns, with green spots decreasing in size as cell density increases.

By exerting “crowd control” over mouse cells, scientists make progress towards engineering tissues

Genes aren’t the sole driver instructing cells to build multicellular structures, tissues, and organs. In a new paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist …

Dr. Justin Ichida’s research focuses on how genetic and environmental factors contribute to human neurodegenerative disease. His laboratory uses cellular reprogramming and stem cell technology to build patient-specific in vitro models of neurodegenerative disease, enabling the screening of drug-like compounds in search of potential therapeutics.
