Summary
Lysosomes, involved in cellular waste degradation, show a correlation with melanin regulation in a 3D skin model. This suggests lysosomes may offer a novel approach for treating hyperpigmentation.
Area of Science:
- Cell Biology
- Dermatology
- Cosmetic Science
Background:
- Lysosomes are essential eukaryotic organelles containing hydrolytic enzymes for cellular waste degradation.
- Melanin protects skin from UV radiation but excess can cause hyperpigmentation.
- Controlling melanin levels is crucial for cosmetic and dermatological applications.
Purpose of the Study:
- To investigate the potential correlation between lysosomes and melanin regulation.
- To evaluate the effect of lysosome on a 3D human skin model (MelanoDerm) for hyperpigmentation treatment.
Main Methods:
- Utilized MelanoDerm, a reconstituted 3D human skin model with melanocytes and keratinocytes.
- Assayed melanin content and measured cell viability after exposure to varying lysosome concentrations.
- Employed 2% kojic acid as a positive control for hyperpigmentation treatment.
Main Results:
- Evidence of a correlation between lysosome and melanin was observed in the MelanoDerm model.
- Lysosome exposure influenced melanin levels and cell viability.
- The study identified a potential role for lysosomes in managing skin pigmentation.
Conclusions:
- Lysosomes demonstrate a potential role in regulating melanin.
- Lysosome may serve as a novel cosmetic agent for addressing hyperpigmentation concerns.
- Further research into lysosome's mechanism in skin pigmentation is warranted.

Pigmentation
4.0K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Lysosomes
25.1K
Lysosomes are membrane-enclosed spherical sacs derived from the Golgi apparatus. The most important function of the lysosome is degrading macromolecules and biological polymers that are released during membrane trafficking events such as the secretory, endocytic, autophagic, and phagocytic pathways. The degradation is carried out by several hydrolytic enzymes active in an acidic environment of the lysosomal lumen. These acid hydrolases are involved in cellular processes such as cell signaling,...

Cells of the Epidermis
6.6K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Changes in Skin Color: Clinical Perspectives
3.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
