Polymer substrates with microneedles for epidermis injection
… top of the substrate itself for release to the epidermis or dermis in stages, which is difficult for both oral medicine and macroneedles. A spectic substrate system with microneedles can prevent irflammation or tear of the epidermis but still puncture for cargo release. Depending on the …

Epidermis and Re-epithelialization in <i>Schmidtea mediterranea</i>
… is essential for tissue recovery. Planarian epidermis enables animal recovery and survival after virtually any body part amputation. Nevertheless, neither the epidermis nor the mechanisms endowing such a remarkable wound healing capacity is described in detail in planarians. Our work …

Regulation of Asymmetric Cell Divisions in the Developing Epidermis
… highly regulated. The development of the mouse epidermis provides a powerful system in which to study the many levels that regulate ACDs. Within the basal layer of the epidermis, both symmetric and asymmetric cell divisions occur. While symmetric divisions allow for an increase in surface area …

Charakterisierung von Epidermis-Typ-Lipoxygenasen mit besonderer Berücksichtigung der e-LOX-3
Epidermis-Typ-Lipoxygenasen bilden zusammen mit den konventionellen Isoenzymen die Familie der Säuger-Lipoxygenasen. Als Dioxygenasen katalysieren sie die stereo- und regiospezifische Insertion molekularen Sauerstoffs in 1,4-cis,cis-Pentadienstrukturen, wie sie in mehrfach ungesättigten Fettsäuren …

A comparative study of the leaf epidermis of forty-two native California ferns
… (1961) have studied cutinized superficial leaf epidermis preserved as fossils. The work of Florin has been particularly important in clarifying the phylogeny of the living conifers</p><p>The questions of the value of the epidermis in the study of the ferns still remains unsolved problem. …

Experimentelle Untersuchungen zur zellbiologischen Charakterisierung Inflammatorischer Dendritischer Epidermaler Zellen in entzündlich veränderter Epidermis
Die entzündlich veränderte Epidermis unterscheidet sich von der Epidermis der normalen Haut durch das Auftreten einer zweiten dendritischen, von Langerhans Zellen (LC) abgrenzbaren Zellpopulation. Während Herkunft und Funktion dieser Inflammatorischen Dendritischen Epidermalen Zellen (IDEC) noch …

Erweiterung eines diagnostischen Verfahrens zur Differenzierung entzündlicher Dermatosen mittels Immunphänotypisierung dendritischer Zellen der Epidermis
… ein krankheitsspezifisches Mikromilieu in der Epidermis und Dermis aufweist und dass sich zweitens dieses spezifische Mikromilieu im Phänotyp der immunkompetenten CD1a positiven epidermalen dendritischen Zellpopulation widerspiegelt, wurde seit 1995 ein Verfahren zur Immunphänotypisierung von …

Development and Verification of Poroelastic Barrier Model With Active Transport: Application in Human Epidermis
… understanding of the mass transfer through the epidermis provides valuable information for different applications such as drug delivery, functioning artificial skin and thermal comfort. We propose a more detailed, physiologically motivated, model in which the outmost layer of the skin is treated …

A Novel Mechanism of Skin Tumor Promotion Involving Interferon-Gamma (Ifnγ)/Signal Transducer and Activator of Transcription-1 (Stat1) Signaling In Epidermis
… (Tyr701) and serine (Ser727) residues in epidermis. CHRY treatment also led to upregulation of unphosphorylated Stat1 (uStat1) at later time points. In addition, CHRY treatment also led to upregulation of IRF-1 mRNA and protein which was dependent on Stat1. Further analyses demonstrated …

The control of melanogenesis in early avian embryos
… (Black Australorp x New Hampshire Red) chick epidermis and dermis have been used to demonstrate that premelanocytes migrate first through the sub-epidermal mesenchyme and then begin to cross into the epidermis from day 4. Results from these grafts and from tritium-labelling studies strongly …

Mechanismy polarizace epidermálních buněk rostlin.
Buňky rostlinné epidermis společně vytváří kontaktní plochu rostliny a chrání ji před vlivy vnějšího prostředí a zprostředkovávají komunikaci s okolím. V epidermis je za pomoci polarizačních mechanismů rovnoměrně rozmístěno několik buněčných typů (dlaždicové buňky, trichomy a průduchy) s velice …

Histopathogenesis of eczma
… afford a mode of entry for the allergen into the epidermis and dermis, causing changes in both these structures, destructive in the epidermis and exudative in the dermis. Oedema fluid and lymphocytes from the upper dermis then force their way into the weakened epidermis to form vesicles. The …

Investigating Differentiation: A Role for Organelle Inheritance in Epidermal Growth
… growth signals. During development, a naïve epidermis undergoes rapid proliferation and differentiation to form skin containing hair follicles, neurons, immune surveillance populations and melanocytes. The epidermis maintains homeostasis through many phases of development including rapid …

Regulation of apoptosis and desmosomes by RhoE
The human epidermis is a self-renewing stratified epithelial tissue that forms the outermost protective layer of the skin. The epidermis is comprised of a number of cell types, the most abundant of which are keratinocytes. Normal function of the epidermis requires that keratinocyte proliferation, …

Epidermal Reactions to Injury with Implications for Innate Immunity
Abstract The epidermis is one of our primary interfaces towards the external milieu. Following injury, the physical barrier function of the skin is destroyed and the epidermis is left vulnerable to microbial invasion. Inducible innate immune response mechanisms exist to keep the wound site free …
