Summary
Researchers isolated multilineage-differentiating stress-enduring (Muse) cells from scalp fibroblasts. These cells demonstrated pluripotency and self-renewal, differentiating into melanocytes, offering potential for regenerative medicine.
Area of Science:
- Stem Cell Biology
- Regenerative Medicine
- Dermatology
Background:
- Multilineage-differentiating stress-enduring (Muse) cells are a unique type of adult stem cell with pluripotency and self-renewal capabilities.
- Dermal fibroblasts are accessible somatic cells that can be a source for isolating stem cells.
- Melanocyte differentiation is crucial for skin pigmentation and wound healing.
Purpose of the Study:
- To isolate Muse cells from human scalp dermal fibroblasts.
- To characterize the pluripotency and self-renewal potential of these Muse cells.
- To investigate their differentiation capacity into melanocytes.
Main Methods:
- Isolation of Muse cells using flow cytometry and anti-SSEA-3 antibody.
- Immunohistochemistry and immunofluorescence staining for cell marker distribution (SSEA-3, Oct4, Sox2, Nanog).
- Reverse transcription polymerase chain reaction (RT-PCR) and Western blot analysis for gene and protein expression (Oct4, Sox2, Nanog, Klf4).
Main Results:
- Muse cells were successfully isolated from scalp dermal fibroblasts and exhibited pluripotency markers.
- Expression levels of key pluripotency genes (Oct4, Nanog, Sox2, Klf4) were significantly different in Muse cells compared to parental fibroblasts.
- Muse cells differentiated into melanocytes, confirmed by the expression of the melanocyte-specific marker HMB45.
Conclusions:
- Scalp dermal fibroblasts can serve as a source for isolating pluripotent Muse cells.
- Muse cells possess self-renewal and multilineage differentiation potential, including towards melanocytes.
- These findings support the potential application of Muse cells in regenerative therapies for skin conditions.

01:19Pigmentation
4.8K
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...

01:24Cells of the Epidermis
8.6K
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...

01:09Introduction to Fibroblasts
4.2K
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...

01:06Multipotency and Niche of Bulge Stem Cell
4.3K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

01:28Forced Transdifferentiation
2.4K
Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

01:13Formation of Muscle Fibers from Myoblasts
6.3K
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription...
