Encapsulated Leptin-Producing Cells Facilitate Entrainment of Circadian Rhythms in Rodents and Nonhuman Primates. [PDF]
Adv Sci (Weinh)A clinically translatable cell line can be engineered to produce leptin, encapsulated in biomaterial and safely implanted to produce and deliver the metabolic regulating protein within the body. Implantation of these encapsulated cells decreases the time it takes for mice and non‐human primates to adjust to circadian disruptions similar to those ...
