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 …

Expression und Funktion der Acyl-CoA-Synthetase 5 in der humanen Epidermis
… to functional relevance of ACSL isoforms in epidermis of human or mouse, especially acyl-CoA synthetase isoform 5 (ACSL5). First of all, ACSL5 expression in human epidermis was investigated in vivo with an histological (mRNA in situ hybridisation, immunohistology) and a molecular (RT-PCR, …

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 …

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 …

Dreidimensionales epidermis-ähnliches Wachstum humaner mesenchymaler Stammzellen auf dermalen Äquivalenten : Einfluss der experimentellen Kulturbedingungen auf Differenzierung, Migration und funktionelles Verhalten
… acid. Human MSC were capable of adaptation to epidermis-specific conditions without losing their mesenchymal multipotency. However, despite the viability and evident three-dimensional epidermis-like growth pattern, hMSC showed a persistent expression of mesenchymal but not of epithelial …

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 …
