It’s a lesser of two evils kind of thing, but unfortunately it still doesn’t tell the full story. The more that senescent cells collect, it turns out, the more they generate pro-inflammatory cytokines. Studies suggest these cytokines directly contribute to increased abnormal cell growth.4For...
it is of great significance to eliminate these senescent cells. Senotherapy is a promising approach emerged in recent years, which refers to selective removal of senescent cells [98]. The use of senotherapy in combination with currently used cancer therapies has been proposed as a more effective...
"The main goal of cellular senescence is to prevent the proliferation of damaged cells that can lead to cancer. However, when damage persists or during aging, senescent cells accumulate abnormally, affecting tissue function and accelerating aging." "This is why it is important to create new syste...
Overabundant synapses were proposed as an endeavor by the brain to generate a diversity of connections beyond genetic anchorage, as activity-induced stabilization selects from the overproduced synapses those to remain [19, 20]. Accordingly, multiple retinal inputs converge onto immature lateral genicul...
Cells continually generate energy, transcribe DNA, transport molecules, make enzymes and divide. These functions all create waste products. Cells need to continually take out the trash or they become tiny junkyards. Some of the waste is swept under the rugs or can’t be cleaned out at all....
The capacity of replicating stem cells to generate daughter cells with the same biological and molecular profile that endows continued renewal potential. This can occur either asymmetrically when a stem cell produces another stem cell and a more differentiated daughter cell, or symmetrically when stem-...

(Figure 1a).4 However, it should be noted that apoptotic blebbing is not a universal feature of programmed cell death, some cell types do not appear to generate membrane blebs nor undergo fragmenta- tion.5 Nonetheless, blebbing is a very common feature of apoptotic cells and has become a ...
(SCDs and ACDs). SCDs generate two identical cells that share the same fat. While ACDs generate a differentiating cell and a self-renewing stem cell. This combination ensures that the stem cell population continues to exist, yet how they contribute to the loss...
