Summary
Keratinocyte (KC) apoptosis is vital for skin development and cancer prevention. This review explores KC apoptosis signaling, control mechanisms, and its complex role in skin cancer using mouse models.
Area of Science:
- Dermatology and Molecular Biology
- Cellular Biology
- Cancer Research
Background:
- Keratinocyte (KC) apoptosis is crucial for epidermal homeostasis, regulating thickness and stratum corneum formation.
- Apoptosis in KCs helps eliminate pre-malignant cells, acting as a barrier against carcinogenesis.
- Dysregulation of KC apoptosis is implicated in skin diseases like psoriasis and skin cancer.
Purpose of the Study:
- To review the current understanding of keratinocyte apoptosis.
- To focus on the signaling pathways and molecular mechanisms controlling KC apoptosis.
- To discuss emerging insights into the role of KC apoptosis in skin carcinogenesis.
Main Methods:
- Literature review of current research on keratinocyte apoptosis.
- Focus on apoptotic signaling pathways and molecular control mechanisms.
- Analysis of findings from mouse models investigating skin carcinogenesis.
Main Results:
- Keratinocyte apoptosis is a key regulator of epidermal development and a suppressor of skin cancer.
- Specific apoptotic pathways and molecular mechanisms govern KC cell death.
- Mouse models provide new insights into the multifaceted role of apoptosis in skin cancer development.
Conclusions:
- Understanding KC apoptosis is critical for addressing skin diseases and cancer.
- Further research into apoptotic signaling pathways can reveal therapeutic targets.
- The complex interplay between KC apoptosis and carcinogenesis requires continued investigation.

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...

01:12Renewal 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,...
01:21Layers of the Epidermis
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
01:19Clinical 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...
01:30Apoptosis
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
