Photoreceptors (PRs) are the primary visual sensory cells, and their loss leads to blindness that is currently incurable. Although cell replacement therapy holds promise, success is hindered by our limited understanding of PR axon growth during development and regeneration.
Amyotrophic lateral sclerosis (ALS) is a fatal neuromuscular disease in which patients gradually become paralyzed due to loss of motor function. Many genetically inheritable mutations have been linked to ALS; however, the majority of ALS patients are considered sporadic.
Over two decades of fundamental research in Parkinson’s disease led by Su-Chun Zhang, MD, PhD, professor of neuroscience and neurology at the University of Wisconsin-Madison and Waisman investigator, has culminated in the development of a promising stem cell-based treatment for the disease.
James Thomson helped the scientific world turn its attention to the shape-shifting stem cells that give rise to all of the building blocks of complex living organisms, from skin and bone, to hearts and blood, to neurons and brains.
Polymeric scaffolds are revolutionizing therapeutics for blinding disorders affecting the outer retina, a region anatomically and functionally defined by light-sensitive photoreceptors. Recent engineering advances have produced planar scaffolds optimized for retinal pigment epithelium monolayer delivery, which are being tested in early stage clinical trials.
The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson’s. Stem cells, which are endlessly adaptable, have offered the promise of better neural repair. But the brain’s precisely tuned complexity has stymied the development of clinical treatments.
New research by University of Wisconsin–Madison scientists reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons.
Lamba’s lab is located at UCSF’s Department of Ophthalmology since 2018 and is currently housed at the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research. His lab develops technologies and in vitro methodologies for generating various retinal cell types, including retinal neurons and retinal pigment epithelium cells, from both human embryonic stem cells and induced pluripotent stem cells.
Human induced pluripotent stem cells (iPSCs) present exciting opportunities to study disease processes in vitro. Advances in bioengineering allow us to differentiate cells in a system more relevant to their native environment in order to observe naturally occurring phenomena.
A recent story on Channel 3000 highlights the efforts by the family of Kenzi Valentyn to raise money for vision research in their daughter’s name. Waisman investigator David Gamm focuses on using stem cells to …
