Fruit-derived stem cells for skin care

By | Discovery

Stem cells possess three key properties: they are unspecialized, they can renew themselves over time and they can develop into cells with specific functions. Stem cells are broadly classified into two types—embryonic and adult stem cells. Embryonic stem cells are pluripotent, meaning they can develop into all cell types in the body and are therefore capable of forming an entire organism. In contrast, adult stem cells generally are multipotent and have the ability to develop into the different cell types within the tissue in which they are found, a process also known as differentiation. Adult stem cells are found in virtually all tissues. Through asymmetrical division, adult stem cells maintain a pool of their own cell type to provide continual repair and regeneration benefits for an organism throughout its life span. Without a pool of effective, proliferating adult stem cells, the continual loss of fully differentiated cells cannot be replenished and the tissue soon loses the ability to function.

Plant Stem Cell Extract for Longevity of Skin and Hair

By | Discovery

Stem cells of an old apple cultivar with very good storage properties were produced by applying plant cell culture technique. The extract of the cultured apple stem cells was shown to enhance the viability of umbilical cord blood stem cells, to reverse senescence signs in human fibroblast cells and to increase lifespan of isolated human hair follicles.

Stimulation of stem cells for rejuvenation

By | Discovery

In contrast to embryonic stem cells, adult stem cells persist for the whole life. They are indispensable to the maintenance and repair of tissues. Some few stem cells in the basal layer of the epidermis produce all the other keratinocytes that differentiate to the stratum corneum and are renewed every four weeks. In older skin, the epidermal stem cells are less active and lower in number leading to wrinkles and an increased renewal time of the epidermis. Plants too have stem cells. After isolation, they can be cultured in liquid media. PhytoCellTecTM Malus Domestica, a preparation of apple stem cells, was found to stimulate the proliferation of human blood stem cells and to increase the lifespan of skin fibroblast cells and of isolated hair follicles. In a clinical trial over 4 weeks with 20 subjects, this new ingredient was found to reduce significantly wrinkles in the crow’s feet area.
