Plant-derived Exosomes for Skin Care

Inquiry

Plant-derived exosomes are tiny natural particles that influence plant development and protect plants from pathogens. Recently, plant-derived exosomes have gained attention for their potential to restore and improve skin.

Why Plant-derived Exosomes can be used for Skin Care?

Plants produce various secondary metabolites such as alkaloids, polyphenols, flavonoids, quinones, and terpenoids when subjected to environmental stresses to defend against pathogens or adapt to their surroundings. These secondary metabolites are often used to provide nutrition or specific benefits to humans. In particular, plant-derived natural substances, such as exosomes, are widely used as cosmeceutical materials for their beneficial effects on human skin, such as anti-aging, moisturizing, whitening, and regeneration.

Biogenesis of Plant-derived Exosomes

The formation and secretion of plant-derived exosomes is a multistep cellular process. First, the plasma membrane invaginates to form early sorting endosomes (ESE) that encapsulate extracellular components and cell membrane proteins. Second, ESEs mature into late-sorting endosomes (LSEs), and LSE membranes invaginate to form multivesicular bodies (MVBs), the MVB pathway being a critical process for the formation of plant-derived exosomes. Finally, MVB fuses with the plasma membrane to release intraluminal vesicles (ILVs) for intercellular communication. In addition, plant-derived exosomes can also be expelled into the plastid via extracellular vesicle-positive organelles (EXPO) in plant cells.

Isolation of Plant-derived Exosomes

Isolation of plant-derived exosomes is mainly based on differential centrifugation. Plant-derived exosomes can be isolated from fruits, flowers, and vegetables. The steps of the conventional method are as follows:

1. The plant is ground into juice and the juice is filtered through a strainer.
2. The collected juice is subjected to differential centrifugation at 3000 x g and 10,000 x g. 2. The supernatant is then centrifuged.
3. The supernatant is then subjected to high-speed centrifugation (100,000-150,000 x g).
4. Since the plant-derived exosomes obtained after differential ultracentrifugation are usually contaminated with nucleic acid and protein clumps, further purification is required by sucrose/deuterium oxidation gradient ultracentrifugation (110,000 × g).

Exosomes in Dermatology

Exosomes contain a variety of biomolecules that help promote skin repair and regeneration. Previous studies have confirmed the therapeutic benefits of exosomes for skin defects such as wounds and aging. For example, it has been found that bioengineered exosomes loaded with miRNA-542-3p promote cell proliferation, collagen synthesis, and wound closure in a mouse model. In addition, exosomes can deliver a variety of bioactive compounds to skin cells, thereby effectively slowing down skin aging and inhibiting photoaging features. In non-invasive treatments, exosomes are incorporated into topical creams, serums, oils, and masks to cover and protect the skin. Exosomes can also be incorporated into bioactive polymeric materials such as hydrogels for sustained release, pH maintenance, and enhanced regenerative potential.

Plant-derived Exosomes for Skin Care

  • Promoting Transdermal Absorption

Transdermal absorption is a major bottleneck in cosmetic skin care, limiting the effective utilization of many ingredients. One of the advantages of plant-derived exosomes is that they are inherently good transdermal systems, capable of penetrating deep into the stratum corneum. Plant-derived exosomes have a lipid bilayer, which is very similar to the liposomes commonly found in skin care products. For example, broccoli-derived exosomes have strong stratum corneum penetration and can encapsulate bioactive molecules that penetrate and distribute into the stratum corneum and dermis.

  • Regulating Hyperpigmentation and Anti-Aging

Plant-derived exosomes have also been extensively studied in skin lightening and anti-aging. Studies have found that ginseng-derived exosomes provide anti-aging benefits to skin cells. Ginseng-derived exosomes ameliorate the aging phenotype of human skin fibroblasts by down-regulating molecules associated with aging and proteins related to melanin formation and ameliorating hyperpigmentation associated with aging of human melanocytes under UV exposure.

  • Promoting Wound Healing and Skin Regeneration

Plant-derived exosomes have emerged as promising tools for promoting wound healing and skin tissue engineering. By delivering growth factors and miRNAs, plant-derived exosomes can initiate signaling pathways that promote cell migration, proliferation, and differentiation. These processes are critical for wound closure, epithelial regeneration, neurogenesis, and angiogenesis. For example, wheat-derived exosomes promote wound repair. Wheat-derived exosomes have a variety of CD markers on their surface and have strong proliferation and migration-promoting effects on endothelial, epithelial, and dermal fibroblasts.
