About Aging Cell

Aging Cell is a scholarly journal published by Wiley-Blackwell Publishing Ltd. SCImago 2025 places it in Q1 with an SJR of 2.881 and an H-index of 191.

Its listed coverage is 2002-2026 and its research categories include Aging (Q1); Cell Biology (Q1). The 2025 dataset reports 407 documents and 6170 citations across the latest three-year reporting window.

Aging is a natural biological process, and at the heart of it lies the behavior of aging cells. Also known as senescent cells, these aging cells stop dividing and begin to deteriorate over time. While this may seem like a simple part of getting older, the process of cellular aging plays a key role in the overall aging of the human body—and it's a hot topic in modern health and longevity research.

What Are Aging Cells?

Aging cells are cells that have permanently stopped dividing but do not die off. This condition is called cellular senescence. While it can be a protective mechanism against cancer (by preventing damaged cells from reproducing), it can also cause harm when too many senescent cells accumulate in the body.

Over time, these cells release harmful substances like inflammatory molecules, growth factors, and enzymes. This mix, known as the senescence-associated secretory phenotype (SASP), can damage surrounding healthy cells, tissues, and even contribute to age-related diseases such as arthritis, heart disease, and Alzheimer’s.

Causes of Cellular Aging

Several factors can cause a cell to become senescent:

  • DNA damage from radiation, toxins, or oxidative stress.

  • Telomere shortening, the gradual loss of protective caps at the ends of chromosomes during each cell division.

  • Oncogene activation, which can signal a cell to stop dividing.

  • Chronic inflammation and environmental stress.

Each of these triggers can push a healthy cell into senescence, starting a chain reaction that affects nearby tissues.

The Role of Senescent Cells in Aging and Disease

As we age, the number of senescent cells in our bodies increases. Unlike healthy cells that divide and renew, senescent cells linger and promote inflammation. This can lead to:

  • Tissue dysfunction

  • Slower wound healing

  • Weakened immune system

  • Higher risk of chronic diseases

Moreover, recent studies have shown that clearing these senescent cells can improve health and potentially extend lifespan in laboratory animals. This discovery has sparked hope in the anti-aging research community.

New Frontiers: Anti-Aging Therapies and Senolytics

Scientists are actively exploring ways to combat the negative effects of cellular aging. One promising area is senolytic drugs—compounds designed to selectively remove senescent cells from the body. Early trials have shown improvements in physical function, skin health, and even cognitive abilities.

In addition, lifestyle choices play a critical role in slowing down cellular aging. Regular exercise, a healthy diet rich in antioxidants, quality sleep, and stress management can reduce cellular stress and delay senescence.
