Senescence vs. sustenance: Evolutionary-demographic models of aging
aging eusociality evolution fertility hydra mortality senescence sustenance
2010/10/14
Humans, and many other species, suffer senescence: mortality increases and fertility declines with adult age. Some species, however, enjoy sustenance: mortality and fertility remain constant. Here we ...
Comparison of Proliferation,Senescence and Differentiation into Skeletal Cell Lineages of Murine Bone Marrow-Derived and Amniotic Fluid Mesenchymal Stem Cells
Amniotic fluid Bone marrow Mesenchymal stem cells Proliferation Differentiation
