The basis of selecting an area as an alternative to using the whole image is to ensure that only keratinocytes from a single tissue layer, in our case mainly the stratum basale were analyzed.
Ultrastructural analysis of the brain tissue (CA1 stratum radiatum of hippocampus) at seven months revealed accumulation of electron-dense storage bodies in Mcoln1 −/− astrocytes similar to those described previously in the cortex [ 25] (Additional file 3: Figure S3A).
10, 11, 17 Human studies have demonstrated that even relatively low doses of UVA given repetitively can induce changes associated with photoaging, including decreased elastic tissue content and stratum corneum thickening.
In addition, glycerol, as a kind of hydrophilic agent, has better optical clearing effect for the tissue under the stratum corneum than lipophilic agents as said in [ 23, 26].
The abscesses mark the dead, not yet cleaned tissue beneath the preserved stratum corneum with a marked boarder line defined by neutrophils with actively proliferating epidermis beneath.
ANOVA was used for multiple comparisons of bacterial load in the various strata of adipose tissue.
However, a stratum of fibrovascular tissue at the matrix-host interface containing microvasculatures and inflammatory cells was observed.
Alternatively Creb1 may have an active role in Sftpd gene transcription since we also show a loss of Sftpd expression in non-lung tissues such as the stratum spinosum epidermal layer in E17.5 Creb1−/− mice compared with robust expression in wildtype mice.
Apart from stratum corneum differences, glandular tissue is far more pronounced in amphibian skin than in mammalian [10].
