Cellular senescence disables proliferation in damaged cells, and it is relevant for cancer and aging. Here, we show that senescence occurs during mammalian embryonic development at multiple locations, including the mesonephros and the endolymphatic sac of the inner ear, which we have analyzed in detail. Mechanistically, senescence in both structures is strictly dependent on p21, but independent of DNA damage, p53, or other cell-cycle inhibitors, and it is regulated by the TGF-β/SMAD and PI3K/FOXO pathways. Developmentally programmed senescence is followed by macrophage infiltration, clearance of senescent cells, and tissue remodeling. Loss of senescence due to the absence of p21 is partially compensated by apoptosis but still results in detectable developmental abnormalities. Importantly, the mesonephros and endolymphatic sac of human embryos also show evidence of senescence. We conclude that the role of developmentally programmed senescence is to promote tissue remodeling and propose that this is the evolutionary origin of damage-induced senescence.

Database of validated Standard Operating Procedures (SOPs) for screens to determine the phenotype of a mouse, developed by the EUMORPHIA consortium. The SOP's cover all of the main body systems including: clinical chemistry, hormonal and metabolic systems, cardiovascular, allergy and infection, renal function, sensory function, neurological and behavioral function, cancer, bone and cartilage, and respiratory function. In addition, there are generic SOPs in histology, necropsy, pathology and gene expression. EMPReSS is a platform of individual tests. These can be performed as individual tests or grouped together in sequences, recommended in the EMPReSS database, to give more information on particular phenotype.
