Un essai clinique ciblant des troubles visuels liés à l’âge ravive l’intérêt pour la reprogrammation partielle, un domaine qui vise à rajeunir des tissus endommagés sans réinitialiser complètement les cellules à un état embryonnaire.

Des chercheurs suédois rapportent une méthode plus fiable pour fabriquer des cellules productrices d’insuline à partir de cellules souches humaines, les cellules transplantées rétablissant pendant des mois le contrôle de la glycémie chez des souris diabétiques.

A study published in Cell Research reports a checkpoint that helps control the identity of multiple stem cell types across developmental stages, pointing to a potentially unifying principle in stem cell biology.

A Nature Medicine research highlight says a phase 1 study found placenta-derived stem cell therapy used during in utero myelomeningocele repair showed promise in an early safety assessment.

Researchers have demonstrated that transplanted neural stem cells can help preserve vision in models of retinal degeneration, offering a potential treatment pathway for conditions that currently have no cure.

Researchers are pairing lab-grown insulin cells with engineered immune bodyguards that prevent rejection — potentially eliminating the need for lifelong immunosuppression.
