  • Tom Lue, MD studies adipose tissue derived stem/progenitor cells.


  • Tippi MacKenzie, MD Fetal surgery was developed at UCSF over 30 years ago as a way of treating select fatal congenital anomalies.  While it has helped hundreds of children with severe anatomic disorders, it is clear that if we could develop safe and effective means of transplanting stem cells into the fetus, we could further transform this field by broadening its scope of diseases.  For example, in utero stem cell transplantation can be used to treat diseases in which stem cells are missing or mutated, such as immunodeficiencies, inborn errors of metabolism, or muscular dytrophy.  Research in our lab is focused on developing safe and effective stem cell transplantation and other therapies for fetuses with congenital anomalies.
