Stem cell and cellular therapy developments.

Recent discoveries on human and non-human stem cells have prompted the development of several studies aimed at the translation of laboratory evidences into novel clinical procedures collectively known as 'cellular therapy'. In this regard, a number of features specifically related to the clinical setting require stringent evaluation, including, but not limited to: ethical appropriateness; donor and recipient informed consent; autologous versus allogeneic use; media and devices for cell collection, processing, characterization, storage and distribution; donor and recipient adverse events registration and management; risk-to-benefit and cost analysis; outcome analysis; production sites accreditation and management; regulatory oversight. This article describes recent national and international developments related to the distribution of cells and tissues for clinical use. Moreover, an example is reported of the implementation of a cellular therapy production site compliant with good manufacturing practices (GMPs) in a large European University hospital.
