Skin also varies in thickness among anatomic location, sex, and age of the individual. (medscape.com)
Autografts consist of the entire epidermis and a dermal component of variable thickness. (medscape.com)
Because the complete dermal component is preserved in full-thickness grafts, more of the characteristics of normal skin are maintained following grafting. (medscape.com)
This is due to the greater collagen content, dermal vascular plexus, and epithelial appendages contained within full-thickness grafts when compared with split-thickness grafts . (medscape.com)
Research has focused mostly on dermal abnormalities, while the epidermis has not yet been studied. (vu.nl)
Chemical peeling, also termed chemexfoliation, represents accelerated exfoliation or skin damage induced by caustic agents that cause controlled damage, followed by the release of cytokines and inflammatory mediators, resulting in thickening of the epidermis, deposition of collagen, reorganization of structural elements, and increases in dermal volume. (medscape.com)

In particular, the bulk of thick skin is a result of the four upper layers of the epidermis: the stratum spinosum, the stratum granulosum, the stratum lucidum, and the stratum corneum. (indianapublicmedia.org)
They damage or completely destroy the entire thickness of the skin. (medlineplus.gov)

Specifically, information about epidermal disposition, step in human skin sensitization induction is the transport of sensitizer from the applied dose on the skin surface to the protein reactivity, epidermal inflammation, dendritic cell epidermis, where innate immune activation occurs. (cdc.gov)
Stratum granulosum1
The named layers of the epidermis include the stratum germinativum, stratum spinosum, stratum granulosum, and stratum corneum. (medscape.com)
Tissue2
However, full-thickness grafts require more optimal conditions for survival because of the greater amount of tissue requiring revascularization. (medscape.com)
We took it to the next step, where we studied [the ingredient's effects] in full thickness epiderm, which is the tissue culture model. (cosmeticsandtoiletries.com)
Punch biopsy1
In such cases, full-thickness incisional or punch biopsy is an acceptable alternative, provided that the procedure allows for accurate primary tumor microstaging and does not interfere with treatment planning. (medpagetoday.com)

In the sorghum caryopsis, the epidermis is composed of thick, elongated, rectangular cells which have a coating of cutin on the outer surface. (fao.org)
The hypodermic is composed of slightly smaller cells than the epidermis and is one to three cell layers in thickness. (fao.org)
The pericarp of the pearl millet caryopsis consists of an epicarp with one or two cell layers, a mesocarp that varies in thickness because of genetic factors and an endocarp made up of cross and tube cells. (fao.org)
The epidermis is mostly made up of flat, scale-like cells called squamous cells. (ukessays.com)
The epidermis of leaves is a continuous layer of cells on all surfaces of the leaf, unbroken except for pores, the stomata ( stoma , singular), which facilitate the exchange of gases between the interior of the leaf and the atmosphere. (cliffsnotes.com)
The parenchyma cells of the epidermis fit together like paving stones and generally contain no chloroplasts except for those in the guard cells of the stomata. (cliffsnotes.com)

The epidermis is derived primarily from surface ectoderm but is colonized by pigment-containing melanocytes of neural crest origin, antigen-processing Langerhans cells of bone marrow origin, and pressure-sensing Merkel cells of neural crest origin. (medscape.com)
Cells of the stratum corneum are the largest and most abundant of the epidermis. (medscape.com)
The most important prognostic indicator for stage I and II tumors is thickness, so a full-thickness biopsy must be obtained for adequate pathologic interpretation. (medscape.com)

The NCCN recommends that the report include Breslow thickness, ulceration status, mitotic rate, deep and peripheral margin status, presence or absence of microsatellites, pure desmoplasia (if present), and Clark level for nonulcerated lesions ≤1.0 mm with undetermined mitotic rate.

Growth1
The growing cases of burn-related emergency department (ED) visits and increasing admissions of patients in hospitals mainly due to partial-thickness or second degree are some of the significant factors propelling the market growth. (grandviewresearch.com)
