Mammalian female reproductive function declines dramatically during aging, as reflected by germ cell pool loss, reduced ovarian endocrine function and an inclination to develop uterine disorders. The Jin lab uses mouse and human models to understand and tackle these problems. First, we are pioneering methods to preserve and study young oocytes before aging initiation via tissue engineering in mice, with the goal of eventually extending this work to humans. Second, we recently identified a novel uterine stem cell population using single-cell lineage tracing in mice, and demonstrated that these stem cells are an important source for uterine homeostasis and regeneration. We are now working to reveal how dysfunction of uterine stem cells or their niche during aging leads to gynecological diseases like cancer and endometriosis. Our long-term goal is to develop stem-cell-based therapeutic strategies. In collaboration with other Buck researchers, we also want to apply our knowledge to understand how reproductive aging impacts aging in other organs, like the brain, in females.
Why it matters
Female aging initiates in the reproductive system then spreads to the whole body. This gender specific aging calendar creates severe health challenges to women. Thus, reproductive health and longevity sets the first key step to women’s wellness.
We are driven by a mission to improve women’s reproductive health, longevity and equality to research ovarian and uterine function and aging.
Shiying Jin, PhD
The Jin lab is pleased to acknowledge the generous support of the following major funders:
Dr. Jin is an assistant professor in the Center for Female Reproductive Longevity and Equality within the Buck Institute for Research on Aging. He received his Ph.D. in reproductive physiology from the China Agricultural University in Beijing. He then had postdoctoral training in reproductive, developmental and stem cell biology at Northwestern University in Chicago as well as in the Department of Embryology, Carnegie Institution for Science in Baltimore. Dr. Jin recently identified the first resident uterine stem cell population in mice. He was awarded the Oncofertility Global Scholar Award by the National Institutes of Health to study female fertility preservation.
Ronald Pandoy Research Associate and Administrative Lab Manager
Ronald received a BS degree in physiology from the University of California, Santa Barbara in 2010. After working for several years, he decided to expand his education and obtained an additional BS degree in biomedical science from La Sierra University in 2016. Upon completing his additional degree, Ronald enrolled at Walla Walla University to pursue a MS degree in biology. There, he completed his thesis in 2019 which focused on protein degradation pathways in the social amoeba Dictyostelium discoideum. Ronald joined the Buck in August 2019. In his spare time, Ronald enjoys all manners of sports and games.
Luyi Zheng, PhD Postdoctoral Research Fellow
Luyi received her MBBS degree in preventive medicine from Fujian Medical University in China in 2011, and her PhD in regeneration and tumor science from Shiga University of Medical Science in Japan in 2017. During her PhD, Luyi studied the effect of Dienogest on ovarian function. Following graduation, Luyi continued her research as a postdoc associate in the same department. Luyi joined the Jin lab in October 2019 where she is studying uterine stem cells and uterus aging. Luyi likes hiking and diving.
