“Stem and Gene Therapy for Cystinosis” – Lay Abstract
... Our previous work has shown that stem cell based gene therapy in a cystinotic mouse model is effective in treating cystinosis. The three major mechanisms under investigation for this type of stem cell based treatment are cellular differentiation, cell fusion, and cell-cell interactions. It is the ob ...
