Meet four junior faculty members from USC Stem Cell. Dr. Megan McCain is engineering stem cell-derived “organ on a chip” models of human heart disease. Dr. Min Yu is developing approaches to target circulating tumor cells to halt the spread of breast cancer. Dr. Joseph T. Rodgers is uncovering signaling networks that coordinate muscle stem cell responses to injury. Dr. Justin Ichida is using patient-specific stem cell-directed systems to model ALS and identify new drug candidates. Together, they are ushering in the medicine of the future—regenerative medicine.
