Mezenkimal Kök Hücreler ve Retinal Pigment Epiteli Arasında İn Vitro Tünelleme Nanotüpleri Yoluyla Mitokondriyal Transfer

Executive Industry Relevance

Bidirectional mitochondrial transfer between mesenchymal stem cells (MSCs) and retinal pigment epithelial cells (ARPE19) via tunneling nanotubes (TNTs) represents a critical mechanism for cellular communication and rescue in disease-relevant systems. Quantitative analysis of mitochondrial exchange informs predictive confidence in cell-based therapeutic strategies and supports mechanistic de-risking at early discovery inflection points. This capability enhances portfolio decision-making by clarifying functional interactions between stem cells and target tissues.
