This book covers a wide range of topics that illustrate the various functions of autophagy in stem cells and offers insights on the mechanisms by which autophagy can regulate stem-cell self-renewal and facilitate specific differentiation programs. Stem cells are unique cells present in most multicellular animals and are essential for their survival. They have two unique properties: the ability to self-renew and the ability to differentiate into one or more cell types. These characteristics of stem cells have found immense therapeutic potential in regenerative medicine. Autophagy is a crucial membrane trafficking pathway that is essential for maintaining cellular homeostasis that involves sequestration of non-functional proteins, protein aggregates and damaged organelles in double-membraned vesicles called autophagosomes, which are subsequently targeted to the lysosome for degradation.
