#epidermis — Public Fediverse posts

Modern #imagingtechnologies allow more #fluorescence insights in #vertebrates. B. Burriel-Carranza et al. (2026) show that the #granularglands and #epidermis of the #firesalamander produce different #fluorophores, and that such compounds also circulate via the #bloodstream. Fluorescence may have a #communicative function.

🚀 #CUTISS is boldly going where no skin has gone before by promising to revolutionize skin defects with 'denovoSkin'—apparently, it's the Tesla of the #epidermis world 🌱✨. Meanwhile, their website is a labyrinthine mess of #buzzwords and sections titled "Our Forest"—presumably where they bury their failed tech. 🌳🔍

New #review today: "#Epidermis is a band with a long history and not a lot of product to show for all that time. The group was founded in Germany in 1971 by members of beat group The Ancestors. But they had higher ambitions, hoping to produce a more complex sound not unlike some of the #ProgressiveRock across the channel in England, with multi-part vocal harmonies and precise instrumental work, inspired by bands like #GentleGiant and #Yes." #ExposeOnline http://expose.org/index.php/articles/display/epidermis-june-1975-3.html

Making jigsaws. During the development of larval #Drosophila #epidermis, compressive forces control the shape of #histoblasts, buckling their apical junctions and changing their morphology from straight to highly folded outlines #PLOSBiology https://plos.io/4ey1BYu

My colleagues recently published a paper on #apoptosis in the #drosophila dorsal #epidermis. They have shown that two factors can predict #cell #extrusion and apoptosis. Cell size sensed by #hippo and relative cell size (compared to neighbors) sensed by #notch

In manchem #Friedhof oder #Hinterhof in #Berlin steht eine #Blutbuche. Das ist eine "normale" #Buche, aber mit roten Blättern. Die Färbung geht auf eine #Mutation zurück, welcher ein #Enzym zum Abbau der #Anthocyane in der #Epidermis fehlt. Erstmals beobachtet wurde die Mutation bei einem Baum in #Thueringen im Jahr 1690. Fast alle Blutbuchen weltweit sind Nachkommen davon. Bis ins Jahr 1926 hat der Ursprungsbaum gelebt. Die Nachkommen dienen heute als #Schmuckbaum #Stadtnatur #Umweltbildung
