Project description
Pericyte loss is the earliest morphological sign of diabetic retinopathy We hypothesize that diabetic retinopathy can be delayed or prevented through restoration of pericytes and pericyte function by adipose tissue-derived stem/stromal cells (ASC). According to surface and internal marker validation, ASCs share pericyte characteristics, and may have a therapeutic benefit in injured microvessels in the eye. The main aims of this project are to i) investigate whether ASC support long-term normalization of the vasculature in the diabetic retina, ii) dissect the molecular mechanisms of ADSC-driven pericyte restoration, iii) evaluate potential immunomodulatory effects of ASC within the diabetic retina.
