Regenerative Medicine Lecture Series

The Regenerative Medicine lectures focus on the latest breakthroughs in stem cell research and involve a partnership with the California Institute for Regenerative Medicine (CIRM).

Presented by the College of Natural Sciences and Mathematics and the Center for Science and Math Success, the Topics in Regenerative Medicine lectures are funded through a CIRM grant in collaboration with the UC Davis Stem Cell Program.

The Secret Lives of Stem Cells Postcard

The Sacramento State Regenerative Medicine Lecture Series welcomes Dr. Lucy O’Brien, Associate Professor Stanford Medical School. Her talk titled “The Secret Lives of Stem Cells: Lessons from the Humble Fruit Fly” will detail her current research using the adult fruit fly to model the dynamics of organ cell populations over time.

Our organs contain multitudes of cells: Mature cells that execute organ function, stem cells that generate new cells, immature cells that are differentiating, and spent cells that will soon be lost. Dr. O’Brien will discuss the demographics and dynamics of these cell populations––their sizes, compositions, and spatial distributions over time--how these demographics shift as organs adapt to new environmental demands, and what happens to cellular demographics when organs become damaged or diseased. The model system used is a simple digestive organ, the midgut of the adult fruit fly. By combining new microscopy and computational approaches with sophisticated genetics, she will uncover how a multitude of individual cells work together to adapt organ form and function across an animal’s lifetime.

Speaker Bio

Dr. O'Brien received her B.A. magna cum laude in Biochemistry from Harvard University. She obtained her Ph.D. in Biomedical Sciences from the University of California, San Francisco, studying how epithelial mini-organs self-organize. She performed postdoctoral research at the University of California, Berkeley, where she switched to stem cell-based epithelial organs in vivo. She is currently a Research Scholar of the American Cancer Society, a Stanford Gabilan Fellow, and a Next Generation Leader of the Society for Stem Cell Research.
