Immunoisolating poly(ethylene glycol) based capsules support ovarian tissue survival to restore endocrine function

A common irreversible adverse effect of life‐saving anticancer treatments is loss of gonadal endocrine function and fertility, calling for a need to focus on post‐treatment quality of life. Here, we investigated the use of poly(ethylene glycol)‐vinyl sulfone (PEG‐VS) based capsules to support syngeneic donor ovarian tissue for restoration of endocrine function in mice. We designed a dual immunoisolating capsule (PEG‐Dual) by tuning the physical...
