Abstract:
Cellular senescence is a ubiquitous stress response that restricts the proliferative capacity of cells. During ageing, senescent cells accumulate in various tissues leading to a number of age-related pathologies and physiological decline. Previously thought to be a process restricted to adult organisms, cellular senescence has been recently demonstrated to occur during embryonic development of animals ranging from fish to mammals. Together, these studies suggest that developmentally programmed senescence is a transient but intrinsic biological process that contributes to the remodelling of developing structures by promoting immune-mediated cell clearance of particular cell populations or modifying the tissue microenvironment. These observations have important implications for the evolutionary origins of this essential, yet paradoxical mechanism.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Language Development
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
