, suggesting a major role in epidermal cell-basement membrane adhesion," Journal of Cell Biology, vol.
Other molecules studied by  are plakins, which represent a family of molecules which form the links between filaments, desmosomes, and hemidesmosomes
and plectin is a cytolinker of this family.
Sertoli cells were connected to each other by intercellular junctions and they were adherent to the basement membrane by hemidesmosomes
. Sertoli cells with euchromatin nuclei and intact cytoplasmic organelles were seen.
The presence of keratinized tissue next to an oral implant presents greater benefits than with natural teeth since the keratinized gingiva has more hemidesmosomes
and hence provides greater strength to the implant soft tissue interface; also, the submerged implant is less likely to become exposed during the healing process.
On TEM images, the number of desmosomes (De) of superficial, wing and basal cells and hemidesmosomes
(Hd) of the basal cells were evaluated.
Under the zonula occludens and forming an axis in an apical-basal direction are three types of adherence junctions: zonula adherens, also known as belt desmosomes; macula adherens, or punctate desmosomes; and hemidesmosomes
. Of these, the first two belong to the adherens junctions, where the adhesion molecules cadherin and catenin are present.
The cytoplasmic extensions formed connections with each other, and with connective tissue in the form of hemidesmosomes
. Although in some areas, these interstitial Cajal-like cells were observed to have basal lamina like homogenous and noncontinuous extracellular substance deposition, it was realized that these cells generally do not have a distinct basal lamina similar with the fibroblasts (Fig.
The peptide compound hexapeptide-10 has been shown to stimulate the formation of laminin-5, alpha6-integrin, and hemidesmosomes
, (4) vital building blocks of the dermo-epidermal junction that allow it to reconstruct connectivity between epidermal and dermal cells.
It is believed that the pathophisiology of laminitis is related to high degradation of the basement membrane (BM), caused by metalloproteases (MMPs), and/or loss of hemidesmosomes
present in the secondary epidermal laminae.
The functional integrity of horn depends on effective epidermal adhesion and this involves proteins such as cadherins and hemidesmosomes
which connect cells to the basement membrane with anchorage by proteins such as integrins.
Desmosomes and hemidesmosomes
: structure and function of molecular components.
The authors described this tumor as consisting of intimately associated cells that contained complicated interdigitating processes, desmosomes, and hemidesmosomes
, thus creating a jigsaw pattern.
