Lab-Grown Breast Tissue Sheds New Light on Lactation Science

Scienmag

Over time, these cells began producing fundamental milk components, such as β-casein—a key milk protein—and milk fat globules, effectively recapitulating aspects of human milk synthesis in vitro. Once these micro-scaffolds were fabricated, the team introduced mammary epithelial cells harvested directly from human breast milk.

Scientists Outline Future Strategies to Reduce Animal Testing

Scienmag

These alternative techniques—encompassing in vitro assays, in silico predictive modeling, and read-across strategies—offer the promise of reducing animal testing while maintaining stringent safety standards. The implications of widely adopting NAMs extend far beyond ethical considerations associated with animal welfare.

Unlocking Epigenetic Secrets of Newborn Pulmonary Hypertension

Scienmag

The analysis of human clinical samples alongside in vitro and in vivo models strengthened the translatability of these findings, bridging the gap between bench and bedside. Persistent pulmonary hypertension of the newborn remains a significant clinical challenge, largely due to the incomplete grasp of its pathological mechanisms.
