Colostrinin delays the onset of proliferative senescence of diploid murine fibroblast cells

Colostrinin™ (CLN), a uniform mixture of low-molecular weight, proline-rich polypeptides, induces neurite outgrowth of pheochromocytoma cells and inhibits beta amyloid-induced apoptosis. Moreover, its administration to patients with Alzheimer’s disease resulted in improved cognitive functions. In this study, we investigated the impact of CLN on the lifespan of murine diploid fibroblast cells (MDF), an in vitro model for cellular aging. Here, we...
