Dr. Filipa Simões is a Group Leader at the University of Oxford and Co-Director of the Oxford Organoid Hub. She discusses how macrophages shape heart development, repair, and regeneration, and how cellular crosstalk within the cardiac niche influences tissue outcomes after injury. Using zebrafish models, stem cell–derived cardiac organoids, and spatial genomics approaches, she explores the molecular signals that govern macrophage identity and function, with the goal of uncovering new strategies to promote cardiac regeneration and limit fibrosis.

The Stem Cell Science Round Up

iPSC Therapy for Heart Failure – Engineered heart muscle grafts derived from iPSCs increased heart wall thickness and improved cardiac function in patients with heart failure.

Inflammatory Memory in HSCs – A distinct human HSC subset retains inflammatory memory, influencing blood production, aging, and disease risk.

Organoid-Mediated Vision Recovery – Transplanted human retinal organoids partially restored vision after complete optic nerve transection in rats.

Improving HSPC Gene Therapy – A new selection strategy enriches precisely edited hematopoietic stem cells while reducing unwanted genomic alterations.
