Examples of keratinocytes in the following topics:
-
- Keratinocytes produce the most important
protein of the epidermis.
- From there the keratinocytes move into the next layer, called
the stratum granulosum.
- The keratinocytes produce a lot of keratin in
this layer—they become
filled with keratin.
- The keratinocytes in this layer
are called corneocytes.
- They divide to form the keratinocytes of the stratum spinosum, which migrate superficially.
-
- However, the pigment of our skin also
involves the most abundant cells of our epidermis, the keratinocytes.
- While melanocytes produce, store, and release
melanin, keratinocytes are the largest recipients of this pigment.
- The transfer of melanin from melanocytes to
keratinocytes occurs thanks to the long tentacles each melanocyte extends to
upwards of 40 keratinocytes.
-
- Hemidesmosomes (HD) are very small stud- or rivet-like structures on the inner basal surface of keratinocytes in the epidermis of skin.
- Together, the HD-anchoring filament complex forms a continuous structural link between the basal keratinocyte keratin intermediate filaments and the underlying basement membrane zone (BMZ) and dermal components.
- Electron microscopic analysis of the epidermal basement membrane zone (BMZ) reveals that it comprises a narrow and sometimes folded interface between the basal keratinocytes and the dermis.
-
- Keratinocytes—epidermal epithelial cells—around the wound site migrate across the wound and close it.
-
- This
is where the skin’s most important cells, called keratinocytes, are formed
before moving up to the surface of the epidermis and being shed into the
environment as dead skin cells.
-
- It is made of stratified squamous epithelium tissues, composed of proliferating basal and differentiated suprabasal keratinocytes that form an extracellular matrix to continually divide as the older outer layers of the epidermis shed.
-
- The papillary layer provides the layer above it, the epidermis, with nutrients to produce skin cells called keratinocytes.
