Transplantation of human pluripotent stem cell (hPSC)-derived neurons into chick embryos is an established preliminary assay to evaluate engraftment potential. Yet, with recent advances in deriving diverse human neuronal subtypes, optimizing and standardizing such transplantation methodology for specific subtypes at their correlated anatomical sites is still required.

Human induced-pluripotent stem cells are a promising resource for propagation of myogenic progenitors. Our group recently reported a unique protocol for the derivation of myogenic progenitors directly (without genetic modification) from human pluripotent cells using free-floating spherical culture.

Generation of Human Induced Pluripotent Stem Cells from Unaffected Neonatal Skin Cells – We have generated and characterized iPSC clones from three unaffected, neonatal individuals using non-integrating episomal reprogramming plasmids expressing OCT4, SOX2, LIN28, KLF4, and c-Myc.

Human pluripotent stem cell-derived neural organoids provide unprecedented potential to recapitulate human brain and spinal cord tissues in vitro. However, organoid morphogenesis relies upon cell-intrinsic self-assembly of biomimetic tissue structures in the absence of normal developmental constraints and morphogen signaling centers.
A decade after stem cell feat, research ramps up
A decade after scientists announced the development of induced pluripotent stem cells, Waisman investigators, including Su-Chun Zhang and David Gamm, continue to use these cells to research and develop potential therapies for several disorders and conditions, such as ALS, Parkinson’s disease, spinal cord injury, and macular degeneration.

Vision research month
June is Vision Research Awareness Month and the Waisman Center is home to a comprehensive vision research program led by David Gamm, MD, PhD. Gamm, a Waisman Center investigator, associate professor of ophthalmology and visual sciences, and Director of the McPherson Eye Research Institute, studies human retinal development and potential therapies for retinal degenerative diseases.
