Dr. De Filippo was named chief of the Division of Urology in 2014, having served interim chief since 2012, overseeing and maintaining the Division’s robust clinical and research programs. Among the many advances made during his tenure, Urology became one of the first surgical divisions at Children’s Hospital Los Angeles to implement electronic medical record-keeping in the outpatient clinic as well as in its extensive satellite network, which includes 15 offices across the Southern California region.

Currently Dr. De Filippo is researching: The development of working renal units from stem cell sources in the laboratory for eventual transplantation in animal recipients as a viable donor kidney source, the use of amniotic fluid stem cells for cell therapeutic modes of therapy in acute and chronic renal failure, FDA-approved phase II clinical trial for tissue engineering of the bladder, isolation of progenitor cells for tissue engineering and cell therapy from amniotic fluid, multipotent stem cells and progenitor cells from amniotic fluid for the treatment of alport disease, the use of multipotent stem cells from amniotic fluid for fetal therapy for alport disease as a model for fetal therapies in genetic diseases of the kidney, the use of multipotent and progenitor stem cells from amniotic fluid for diabetes and diabetic nephropathy.

Research Overview

Roger De Filippo, MD and Laura Perin, PhD, principal investigators and co-directors of the GOFARR Laboratory for Organ Regenerative Research and Cell Therapeutics in Urology, focus on the development of new stem cell therapeutics and other techniques for organ regeneration.

Using a model for Alport’s Syndrome, a kidney disease characterized by progressive renal fibrosis, the research team injected Amniotic Fluid Stem Cells (AFSC) early in the course of the disease and found that the treatment increased survival time and ameliorated the decline in kidney function.

Kidneys are responsible for filtering toxins from the blood. Chronic kidney disease (CKD) affects millions of children and adults in the United States.  Characterized by a progressive decline in kidney function, CKD leads to an increase in health problems, including heart disease and diabetes. Those who develop end-stage kidney disease depend on dialysis to clear the waste from their blood and, ultimately, most patients require a kidney transplant in order to survive. With such stark long-term consequences, this novel research offers hope to those suffering from the disease and is also a significant advancement in the stem cell research field.

Stem cell therapies have emerged over the last twenty years as a promising new area of biomedical research. While embryonic stem cells remain a controversial subject, AFSC are found in the fluid surrounding a fetus. The cells can be collected via amniocentesis or at birth without any harmful effects. The lab’s research demonstrates that the therapeutic benefit of AFSC is similar to that of embryonic stem cells.

Current projects include kidney organ repair techniques with stem cells, as well as, new stem cell therapy studies for lung, heart, diabetes and kidney diseases. The goal is to search for potential applications that could be used to prevent these diseases and significantly delay the damage they cause.
