Rejenevie™ is developing a heterochronic cell culture model to stimulate the function of hematopoietic stem cells (HSCs). The Rejenevie™ approach uses the hematopoietic and immune systems as a model to identify differential relationships between youthful and aged systems, providing a way to isolate restorative factors that target key causal aging mechanisms. The result is new therapies and interventions that can prevent or delay aging-related diseases.
