My annual Valentine’s post of this image that happens to land on #FluorescenceFriday this year! An axon approaching a kidney glomerulus doing its best to look like a rose.

An old favorite for this #FluorescenceFriday. This "rose" is actually a kidney glomerulus (red, podocytes) and an axon reaching towards it (green).
Kidney microscopy image that looks just like a rose. The glomerulus is red and looks like a ball of petals and a green axon looks like a long stem.

High definition image of a dead star.
This is Cassiopeia A, a star that died 320 years ago.
This image was presented today on AAS Nova (ApJL).

A roughly circular cloud of gas and dust with complex structure. The inner shell is made of bright pink and orange filaments studded with clumps and knots that look like tiny pieces of shattered glass. Around the exterior of the inner shell, there are curtains of wispy gas that look like campfire smoke. Around and within the nebula, various stars are seen as points of blue and white light. Outside the nebula, there are also clumps of dust, coloured yellow in the image.

This cryosection of a #zebrafish mesonephros reminds me of a creature's head. The glomerulus is staring directly at me. Doesn't it?

Something a bit different for day 8 of #ArtAdventCalendar - a marble run #glomerulus sculpture with interdigitating podocytes for public engagement activities, now in the care of #BristolRenal.

Plastic fishtank piping, modroc, modelling clay and acrylic paint (2017).

The glomerulus is the structure in the kidney that filters waste and small molecules from the blood into the urine. Thick tubing is haphazardly coiled to demonstrate the flow of blood through the glomerulus. The vessels split and become smaller to increase the surface area for filtration. The structure is painted raw sienna. Blue and raw sienna podocytes made from modelling clay interdigitate to form the size-selective filtration barrier.

Mesonephric glomeruli of #zebrafish for #FluorescenceFriday 🔬
kdrl-mCherry nicely reveals the capillary tuft of the glomerulus.

The zebrafish kidney stops developing at the mesonephros stage! It serves as their main kidney structure, and they don't develop a metanephros like humans do.

Bronzed olfactory sensory neuron axons make a dramatic entrance from the 👃 into the 🧠, rolling up into perfect scent spheres in the olfactory bulb. During development & regeneration, neurons with the same receptor find their way to the same glomerulus, creating a smelly map 🗺️ #FluorescenceFriday

Pathologies of 🐷 to human kidney transplant

3 patients - from Jayme Locke et al in @ajkd.bsky.social

Mesangial IgM/C4 deposits + cellularity seen even preimplantation, endothelial injury, even (viral) inclusion in one case

#transplant #nephsky #renalpath
Fi gure 1 Case 1 xenografts. (A) Left preimplantation biopsy shows glomerulus with mild increase in mesangial matrix and segmental increase in mesangial cellularity (PASH x20). (B) Right postimplantation biopsy, POD-2, shows diffuse tubular epithelial cell necrosis with loss of nuclei and frequent granular casts. The glomerulus shows rare lumina occluded by fibrin thrombi (arrows); the rest of the capillaries are congested (PASH x20). (C) Left preimplantation biopsy; immunofluorescence shows global granular staining for IgM limited to the mesangium (FITC anti-human IgM). (D) Right preimplantation biopsy shows electron dense immune complex deposits within the expanded mesangium (Uranyl acetate and lead citrate, x4000). (E) Low power of the biopsy in D shows nearly intact foot processes; the mesangial matrix and cellularity is mildly increased, and the glomerular basement membrane appears thin (Urinayl acetate and lead citrate x1600). (F) Right postimplantation biopsy, POD-2, shows severe endothelial cell injury with loss of endothelial cell nuclei; the lumina are completely obliterated by degenerated swollen endothelial cells, fibrin tactoids (arrow) and entrapped fragmented red blood cells; the foot processes are completely effaced (Uranyl acetate and lead citrate, x3200). Figure 2 Case 2 xenografts. (A) Left preimplantation biopsy shows glomerulus with mild increase in mesangial matrix and segmental increase in mesangial cellularity; adjacent arteriole is unremarkable (PASH x20). (B) Left postimplantation biopsy, POD-3, there is moderate to severe acute tubular injury showing luminal dilatation with tubular epithelial cells simplification and frequent casts within injured tubular lumen and interstitial edema; the glomerulus, in addition to mildly increased mesangial matrix and mild mesangial hypercellularity, shows scattered inflammatory cells including PMNs (arrow) within the capillary lumina lined by swollen endothelial cells with segmental partial to near complete obliteration of the peripheral capillary lumina (PASH x20). (C) Left preimplantation biopsy; immunofluorescence shows weak but global granular staining for IgM limited to the mesangium (FITC anti-human IgM). (D) Left postimplantation biopsy, POD-1; immunofluorescence shows strong and global, granular staining for C3 predominantly limited to the mesangium (FITC anti-human C3). (E) Right preimplantation biopsy; the foot processes are nearly intact; the glomerular basement membrane appears thin (Uranyl acetate and lead citrate x3400). (F)Left preimplantation biopsy; and (G) Left postimplantation biopsy, POD-1; there are frequent electron dense immune complex deposits within the expanded mesangium (Uranyl acetate and lead citrate, x5800 and 3400 respectively). (H) Right postimplantation biopsy, POD-3, the capillary loops are lined by swollen endothelial cells with partial to near complete obliteration of the lumina; the foot processes are partially effaced (Uranyl acetate and lead citrate x2600). (I) Right postimplantation biopsy, POD-3, high power view of the glomerulus in H shows intraluminal fibrin tactoids (arrow), in addition to the subendothelial electron densities (asterisk) with microvesicular architecture (Uranyl acetate and lead Figure 3 Case 3 xenografts. (A) Left preimplantation biopsy shows glomerulus with mild increase in mesangial matrix and segmental increase in mesangial cellularity; there is no tubulointerstitial injury (PASH x20). (B) Left postimplantation biopsy, POD-7, the peritubular capillaries (arrows) contain inflammatory cells indicative of peritubular capillaritis; the tubulointerstitium shows moderate acute tubular injury and interstitial edema (PASH x20). (C) Left postimplantation biopsy, POD-3, the C4d stain is negative in the peritubular capillaries (C4d immunohistochemical stain x20). The C4d is focally positive in peritubular capillaries in postimplantation, POD-5 (D) and diffusely positive in postimplantation, POD-7 (E) biopsies (C4d immunohistochemical stain x20). (F) Right postperfusion biopsy; immunofluorescence shows global granular staining for C3, limited to the mesangium (FITC anti-human C3). (G) Right preimplantation and (H) right postperfusion biopsies; the foot processes are nearly intact; the glomerular basement membrane appears thin (Uranyl acetate and lead citrate x2600 and 1450 respectively). (I) Right postperfusion biopsy on higher power shows rare electron dense immune complex deposits (arrow) within the expanded mesangium (Uranyl acetate and lead citrate x7900). (J) Right postimplantation biopsy, POD-7, shows mildly increased mesangial matrix and segmentally swollen endothelial cells; however, no significant foot process effacement is present (Uranyl acetate and lead citrate, x2600).
