Summary
This study details six methods to assess cell death in human keratinocytes, crucial for cancer research. These techniques help researchers quantify and qualify cell death, including necroptosis, in vitro.
Area of Science:
- Biochemistry
- Cell Biology
- Dermatology
Background:
- Cell death characterization is vital in biological research.
- Necroptosis, a programmed necrosis, is increasingly recognized for its role in skin biology and disease.
- Accurate methods for assessing cell death are critical for cancer research and therapeutic development.
Purpose of the Study:
- To describe six distinct in vitro methods for evaluating cell viability and cell death in cultured human keratinocytes.
- To provide researchers with tools to study the quality and quantity of cell death, including necroptosis.
Main Methods:
- Crystal violet assay for cell viability.
- Hypodiploidy analysis for cell cycle assessment.
- Caspase-8 cleavage assay for apoptosis detection.
- High-mobility group box 1 (HMGB1) release assay.
- Annexin V/propidium iodide (PI) co-staining for apoptosis and necrosis.
- Hoechst/SYTOX green co-staining for cell viability and death.
Main Results:
- The study outlines a comprehensive panel of assays applicable to human keratinocytes.
- Each method offers specific insights into different aspects of cell death.
- The described techniques facilitate the quantitative and qualitative analysis of cell death processes.
Conclusions:
- Six validated methods are presented for the robust assessment of cell death in keratinocytes.
- These assays are essential for advancing the understanding of cell death mechanisms in skin biology and cancer.
- The findings support the development of targeted cancer therapies by enabling precise cell death analysis.

01:24Cells of the Epidermis
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...

01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
01:11Cellular Injury IlI: Cellular Death
Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...
01:12Renewal 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,...
