RENEW Biobank

We have currently placed a pause on accepting new donations for the RENEW Biobank until further notice. Thank you for your support.

The RENEW Biobank is located at the Center for Human Embryonic Stem Cell Research and Education (hESC) in the Stem Cell Biology and Regenerative Medicine Institute. The Center builds on the established excellence of the Institute, in combination with the Department of Obstetrics and Gynecology, by focusing on four areas of primary importance in stem cells research:

  1. Human embryology
  2. Germ cell development
  3. Reprogramming cells
  4. Directed differentiation of stem cells to other cell types

Reasons for Patients to Donate

  • Each IVF cycle generates a small excess of unusable biological materials. You have the opportunity to donate those discarded IVF materials for research at Stanford.
  • Research on in vitro fertilization and the human embryo prior to implantation is necessary if we are to understand human development and treat a wide range of human disorders including infertility.
  • Advances in human embryonic stem cell (hESC) research may some day lead to new treatments for adult diseases such as diabetes, Parkinson's disease, spinal chord injuries or Alzheimer's disease.
