Advances in Gerontology = Uspekhi Gerontologii
|May 8, 2015
Summary
New peptides, LK and AEDG, effectively stimulate skin fibroblast proliferation in both young and old rats. This research offers a novel approach for developing advanced cosmetology substances.
Area of Science:
- Gerontocosmetology
- Dermatology
- Molecular Biology
Context:
- Investigating novel low-molecular substances for anti-aging cosmetic applications.
- Understanding the impact of aging on skin cell response to active compounds.
Purpose:
- To evaluate the efficacy of LK and AEDG peptides on skin fibroblast proliferation in organotypic cultures.
- To compare the effects of these peptides on young and aged skin cell models.
Summary:
- LK and AEDG peptides significantly stimulated fibroblast proliferation by 29-45% in both young and old rat skin cell cultures.
- The stimulatory effect was observed within a concentration range of 0.05-2.00 ng/ml.
- A reduced concentration range and level of stimulation were noted in aged skin cells compared to younger ones.
Impact:
- These findings pave the way for the development of new cosmetology products based on LK and AEDG peptides.
- Provides a scientific basis for utilizing these peptides in anti-aging formulations.
- Highlights potential differences in peptide efficacy related to cellular aging.

01:12Renewal of Skin Epidermal Stem Cells
3.3K
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...

01:19Clinical Applications of Epidermal Stem Cells
3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:23Tissue Renewal without Stem Cells
2.3K
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.

01:19The Effect of Aging on Tissues
4.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:19Overview of Regeneration and Repair
6.2K
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.
