Advanced Toolboxes for Cryobioprinting Human Tissue Analogs.

The increasing demand for biofabricating human tissue analogs for therapeutic applications has encouraged the pursuit of innovative techniques that shift from conventional bioprint-to-use approaches toward instantaneous bioprint-cryopreserve strategies. Such enabling concepts and next-generation technologies open new possibilities for fabricating shelf-ready living constructs for applications in regenerative medicine, preclinical disease modeling, and beyond. The generation of living constructs either for short- or long-term cryostorage requires, however, a careful design of cryoprotective bioinks to maximize biofunctionality and limit cell damage during processing.

Epigenetic reprogramming as a key to reverse ageing and increase longevity.

The pursuit for the fountain of youth has long been a fascination amongst scientists and humanity. Ageing is broadly characterized by a cellular decline with increased susceptibility to age-related diseases, being intimately associated with epigenetic modifications. Recently, reprogramming-induced rejuvenation strategies have begun to greatly alter longevity research not only to tackle age-related defects but also to possibly reverse the cellular ageing process.
