Summary
Efficiently removing damaged cells is crucial for tissue repair. This review explores how apoptosis and senescence impact tissue homeostasis, highlighting mechanical strategies to reverse senescence and restore function.
Area of Science:
- Cellular biology
- Tissue homeostasis
- Mechanobiology
Background:
- Tissue integrity relies on clearing damaged cells, with outcomes including apoptosis and senescence.
- Apoptosis facilitates rapid removal, while senescent cells persist, causing chronic inflammation and tissue disruption.
- Current methods to clear senescent cells have limitations.
Purpose of the Study:
- To review the distinct roles of apoptosis and senescence in epithelial tissue homeostasis.
- To explore the challenges in clearing senescent cells and restoring tissue function.
- To highlight emerging mechanobiological strategies for reversing senescence.
Main Methods:
- Review of existing literature on cellular damage responses, apoptosis, and senescence.
- Analysis of immune-mediated clearance and senolytic drug efficacy.
- Examination of mechanobiological approaches like ultrasound and geometric confinement.
Main Results:
- Apoptotic cells are efficiently cleared, whereas senescent cells resist elimination.
- Senescent cells contribute to chronic inflammation and tissue remodeling.
- Mechanobiological strategies show promise in reversing the senescent phenotype.
Conclusions:
- Efficiently clearing or reversing senescent cells is essential for tissue repair.
- Mechanical forces offer a novel approach to restore tissue function by targeting senescence.
- Harnessing mechanobiology presents a promising therapeutic avenue for age-related tissue dysfunction.

01:11Healing I: Introduction
Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...
01:19Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:23Tissue Renewal without Stem Cells
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:28Phases of Wound Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
