Here we show our method to isolate mouse epidermal neural crest stem cells (EPI-NCSC). Technique involves micro-dissecting whisker follicles, isolating the bulge and placeing it into tissue culture. EPI-NCSC start to emigrate from bulge explants onto the substratum within 3 - 4 days.

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...

2023
The plasma-isolated exosomes can be used as a non-invasive and repeatable way for the detection and follow-up of the biomarkers for early detection and disease progression. This video describes the protocol for the separation of exosomes from the plasma samples of non-small cell lung cancer patients, which could be used for DNA and protein extractions.
FAQs
The lipid bilayer helps preserve exosomal cargo as vesicles transport signals between cells. After recipient cells internalize them, proteins, messenger RNA, and microRNA can influence signaling, gene expression, and cellular behavior. This creates a mechanistic connection between epidermal stem cells and measurable changes in responding cells, allowing researchers to investigate how vesicle uptake contributes to skin biology.
Cargo composition determines which biological signals these vesicles can deliver. Proteins may affect cellular signaling directly, while messenger RNA and microRNA can influence gene expression in recipient cells. Examining defined cargo therefore helps researchers relate particular molecular contents to changes in cell behavior and to distinguish possible communication pathways involved in epidermal maintenance, repair, or regeneration.
The targeting potential of these vesicles may influence which recipient cells respond to their cargo. Internalization by a compatible recipient cell can connect the delivered signals with changes in signaling, gene expression, or behavior. This feature is important because it gives researchers a way to study communication selectively, rather than treating all cells in skin tissue as equally responsive.
Researchers can examine their molecular contents, how recipient cells internalize them, and which changes follow in signaling, gene expression, or cellular behavior. These observations help connect vesicle communication with tissue-level processes. In epidermal biology, the resulting evidence is used to study maintenance, wound healing, and regeneration without assuming that every vesicle produces the same response.
Their roles are examined in tissue maintenance, wound healing, and regeneration because each process requires coordinated communication between cells. Studying how epidermal stem cell exosomes affect recipient-cell signaling and behavior can reveal mechanisms associated with repair or renewal. The findings may clarify how epidermal tissues respond during normal maintenance and after injury.
Their defined molecular contents and cell-targeting potential make them useful for investigating skin repair mechanisms without using the originating cells as the therapeutic focus. Researchers can relate cargo and recipient-cell responses to possible repair effects, supporting the development of cell-free approaches to dermatological therapy. This also connects basic vesicle biology with regenerative and clinical research goals.
