Plant stem cells in cosmetics powerpoint presentation

The Plant Stem Cells in Cosmetics presentation explores the use of plant stem cells in the cosmetic industry, highlighting their unique properties and applications. Plant stem cells, found in meristematic tissues, are undifferentiated cells capable of reverting to their original state through natural reprogramming, unlike animal stem cells. They are a source of active substances like polyphenols and flavonoids, which contribute to anti-aging properties.

The propagation of plant stem cells in culture and the extraction of their beneficial compounds have led to the development of various cosmetic products. For instance, Gardenia jasminoides and Echinacea purpurea extracts have been found to prolong fibroblast life and regulate cell division, respectively. Syringa vulgaris and Citrus sinensis extracts aid in epidermis reconstruction and protection against UV radiation. Kinetin, a cytokinin found in citrus fruits and raspberries, has been identified as a potent inhibitor of the human cell aging process.

The document also discusses the protective effects of plant stem cell extracts on human stem cells, as evidenced by the Uttwiler spatlauber species, which significantly reduced cell death when cultured with the extract. Additionally, PhytoCellTecTM Malus domestica cream has been reported to reduce wrinkle depth after two and four weeks of application, demonstrating an anti-wrinkle effect.

Marketed products featuring plant stem cell extracts include those derived from Uttwiler spatlauber, tomato, and Leontopodium alpinum, which offer anti-collagenase and anti-aging benefits. The document concludes that the identification of genes responsible for the beneficial traits of plant stem cells could accelerate natural healing and enhance the healthcare system’s goals.

5. Plant stem cells vs animal stem cells In mammals, the biggest drawback of stem cells is that specialized cells are unable to return to their original undiferentiated state. This limitation is overcome in case of plant stem cells which are capable of reverting to their original state without any external manipulation. Plants undertake a natural reprogramming process in order to replenish their stem cells. 5

8. kinetin According to some studies, one of the strongest inhibitors of the human cell aging process is kinetin, which is a cytokinin found in high concentrations in stem cells of, for example, citrus fruits and raspberries. 8

9. Protecting human stem cells Uttwiler spatlauber species It was concluded that 50% of the cells cultured in the growth medium alone died, whereas the cells which were cultured in the presence of an extract of stem cells from Uttwiler spatlauber were found to have experienced only a small loss in terms of their viability. 9

10. Senescence is described as a natural process in which after dividing 50 times, the cell loses its ability to undergo any further divisions Reversing signs of senescence in fbroblast cells 10

11. Anti‑wrinkle effect The application of PhytoCellTecTM Malus domestica cream was reported to markedly reduce the depth of the wrinkle after a period of 2 weeks and then 4 weeks. 11

13. 13 conclusion The extracts obtained from plant stem cells are a source of many active substances, such as polyphenols, phenolic acids, triterpenes, flavonoids, carotenoids, fatty acids, sugars, and peptides, which give the anti-aging properties. It will prove to be a highly rewarding proposition if the genes responsible for conferring the benefcial traits of stem cells on humans are identifed . This would hasten the process of natural healing, achieving yet another goal of the healthcare system. 1 2
