Summary
Stem and germ cells protect their DNA using efflux machinery, low metabolic activity, and hypoxic environments. Hyaluronan (HA) plays a crucial, often overlooked, role in shielding DNA from oxidative damage in these vital cells.
Area of Science:
- Cell biology
- Genetics
- Biochemistry
Background:
- Stem cells and germ cells are crucial for maintaining genome integrity.
- Protecting DNA from damage is essential for cellular function and reproduction.
Purpose of the Study:
- To review mechanisms protecting DNA in stem and germ cells.
- To highlight the antioxidant role of hyaluronan (HA) in genome preservation.
Main Methods:
- Review of existing literature on DNA protection mechanisms.
- Analysis of hyaluronan's function in stem and germ cells.
- Examination of hyaluronan's antioxidant properties.
Main Results:
- Mechanisms include efflux pumps, reduced metabolic activity, and hypoxic niches.
- Hyaluronan and its receptors are present in stem and germ cell environments.
- Hyaluronan actively protects DNA from oxidative damage through its antioxidant activity.
Conclusions:
- Multiple mechanisms contribute to genome integrity in stem and germ cells.
- Hyaluronan's antioxidant function is significant for preserving DNA integrity.
- Further research into hyaluronan's role could offer new therapeutic avenues.

01:19Multipotency of Hematopoietic Stem Cells
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
01:26Stem Cell Niche
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
01:01Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
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,...
01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
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.
