Research Interests
Retinal progenitor sheet transplantation and demonstration of vision improvement in models of retinal degeneration and ultimately in retinal degeneration patients (Retinitis Pigmentosa, age-related macular degeneration)
Academic Distinctions
Dr. Seiler’s Ph.D. in 1985 (LMU University of Munich, Max Planck Institute for Psychiatry, Dept. Neurochemistry) focused on neurotrophic factors in the central nervous system, followed by postdoctoral studies in retinal transplantation in Winston-Salem, NC and Boston, MA. She was Assistant Professor at the University of Louisville, KY from 1993-2002, and at the Doheny Eye Institute, USC Department of Ophthalmology 2002-2006.
In a collaboration lasting more than 30 years with her colleague, Dr. Robert Aramant, they developed and refined a unique procedure of retinal progenitor sheet transplantation, which has demonstrated improvement of visual responses in the superior colliculus in 4 different retinal degeneration models (RCS rats, rd mice, rho S334ter line 3 and line 5 rat models of fast and slow retinal degeneration). Dr. Seiler participated in Phase I and II clinical trials to transplant sheets of fetal retina with its RPE to patients with retinal degeneration (retinitis pigmentosa and age-related macular degeneration). The phase II trial showed improvements of visual acuity (EDTRS) in 7 of 10 patients (reference

From 2007-2014, she was the lead researcher of the retina project of the Research group of Dr. Hans Keirstead at UC Irvine (now CEO at AiVita Biomedical Inc.). In 2014, she received a 3-year Early Translational grant from CIRM with the goal of developing human embryonic stem cells to transplantable 3-D sheets of retinal progenitor cells for vision restoration. In 2018, she received a 4.7 million TRAN1 grant (2.5 years) entitled “Morphological and functional integration of stem cell derived retina organoid sheets into degenerating retina models.” that will develop this application towards a treatment for Retinitis Pigmentosa (see press release

Research Abstract
The goal of Dr. Seiler’s research is to develop retinal progenitor sheet transplants as a clinical treatment for retinal diseases such a Retinitis Pigmentosa and age-related macular degeneration, which affect both photoreceptors and retinal pigment epithelium (RPE). The current focus of her research is to develop human embryonic stem cells (hESCs) into transplantable sheets of 3D retina and RPE and to demonstrate vision restoration at the level of the superior colliculus and visual cortex in rat models of retinal degeneration. She has also been collaborating with Dr. Cummings to investigate whether human mesenchymal stem cells reverse retinal pathology and functional deficits resulting from repeated brain trauma.
