Aging is accompanied by the decline of organismal functions and a series of prominent
hallmarks, including genetic and epigenetic alterations. These aging-associated epigenetic …

Most adult organs contain regenerative stem cells, often organized in specific niches. Stem
cell function is critical for tissue homeostasis and repair upon injury, and it is dependent on …

Caloric restriction (CR) prolongs life span, yet the mechanisms by which it does so remain
poorly understood. Under CR, mice self-impose chronic cycles of 2-hour feeding and 22 …

Skeletal muscle contains a designated population of adult stem cells, called satellite cells,
which are generally quiescent. In homeostasis, satellite cells proliferate only sporadically …

Health is usually defined as the absence of pathology. Here, we endeavor to define health
as a compendium of organizational and dynamic features that maintain physiology. The …

The circadian clock evolved in diverse organisms to integrate external environmental
changes and internal physiology. The clock endows the host with temporal precision and …

Ageing is characterized by the functional decline of tissues and organs and the increased
risk of ageing-associated disorders. Several 'rejuvenating'interventions have been proposed …

Circadian clocks are endogenous oscillators that control 24-h physiological and behavioral
processes. The central circadian clock exerts control over myriad aspects of mammalian …

Dietary restriction (DR) decreases body weight, improves health, and extends lifespan. DR
can be achieved by controlling how much and/or when food is provided, as well as by …

Skeletal muscle has remarkable regeneration capabilities, mainly due to its resident muscle
stem cells (MuSCs). In this review, we introduce recently developed technologies and the …
