Collagen! Hyaluronic acid! Elastin, too!? Dermal stem cells-the origin of skin plumpness.
Stem cells have the "self-duplication capability," a function to divide and make copies of themselves, and the "differentiation capability," which is a function to make various types of cells.
It is the work of the stem cells which helps to maintain our bodies healthy and heal wounds.
Recently in the medical field, research has been active on "regenerative medicine," which utilizes the stem cells to repair illness- and injury-damaged organs and tissues.
The iPS cell is a type of stem cells, known for research which brought Nobel Prize in Physiology or Medicine to the academic area.
There are two types of dermal stem cells - "dermal stem cells" and "epidermal stem cells." Each type has its own role.
Skin consists of (top - bottom) epidermis, dermis, and subcutaneous tissues.
Dermal stem cells ? despite their significance as the origin of supple skin ? had not been made subject of research; their precise locations, characteristics, and their effect on aging process had been unknown.
Shiseido initiated the research on dermal stem cells in 2004. After conducting a series of thorough research, we discovered new facts that would help us lead to anti-aging solutions.
Based on these new findings, Shiseido has been conducting research on the expression of growth factors, which tends to diminish with age. In hopes to develop anti-aging solutions to help enhance dermal regeneration/repairing capabilities, we continue to put in effort and make progress.
We may soon be saying "Supple skin? As you wish!" ...who knows?
