Summary
Plant epidermal cell patterning, including trichomes and stomata, is key to land adaptation. This review explores how these patterns vary across species and organs, influenced by development and environment.
Area of Science:
- Plant Biology
- Developmental Biology
- Cell Biology
Background:
- Plants possess specialized epidermal cells crucial for terrestrial life.
- The arrangement of these cells, particularly trichomes and stomata, dictates their function.
- Recent advances reveal molecular mechanisms of trichome and stomata patterning in Arabidopsis.
Purpose of the Study:
- To review and compare the patterning of stomata and trichomes across diverse plant species and organs.
- To investigate environmental and developmental factors influencing epidermal cell patterning.
- To explore the relationship between cell patterning and specialized epidermal cell function.
Main Methods:
- Comparative analysis of stomata and trichome patterning in various plant species.
- Review of literature on environmental and developmental influences on cell patterning.
- Discussion of the functional implications of altered cell patterning.
Main Results:
- Plant epidermal cell patterning is not universal and varies significantly across species and organs.
- Environmental and developmental cues dynamically regulate the arrangement of specialized epidermal cells.
- Changes in patterning are directly linked to the functional adaptations of these cells.
Conclusions:
- Understanding epidermal cell patterning is vital for comprehending plant adaptation and multicellular integration.
- Further research into patterning mechanisms will enhance knowledge of plant physiology.
- The study highlights the plasticity of plant epidermal development in response to environmental and developmental signals.

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,...
01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

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...

02:19Morphogenesis
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
