Microscopy observations reveal a new glandular morphology in four Pinguicula L. species.

The adaxial leaf surface of butterworts (Pinguicula L.) presents specialized structures for carnivory, such as trichomes and sessile glands. The micromorphology of abaxial leaf surfaces has rarely been investigated; therefore, this study aimed to compare the micromorphology of adaxial and abaxial surfaces through electron scanning microscopy (SEM) and light microscopy (LM).

Telocytes: Detection, Visualization, Tissue Dissociation, and Tamoxifen-Induction of Transgenic Mice.

Telocytes, distinctive interstitial cells, have recently emerged as crucial components of the stem-cell niche in the intestine. Notably, telocytes are distinguished by their extremely long cellular protrusions extending hundreds of microns from the cell body, forming an interconnected network along the intestinal crypt villus axis. Due to these unique cellular characteristics, there is a need for tailored working protocols to effectively characterize and target telocytes.

Isolation of Murine Intestinal Mesenchyme Resulting in a High Yield of Telocytes.

The murine small intestine, or colon mesenchyme, is highly heterogenous, containing distinct cell types including blood and lymphatic endothelium, nerves, fibroblasts, myofibroblasts, smooth muscle cells, immune cells, and the recently identified cell type, telocytes. Telocytes are unique mesenchymal cells with long cytoplasmic processes, reaching a distance of tens to hundreds of microns from the cell body. Telocytes have recently emerged as an important intestinal stem cell niche component, providing Wnt proteins that are essential for stem and progenitor cell proliferation.

Marker-Assisted Pyramiding of Blast-Resistance Genes in a Elite Rice Cultivar through Forward and Background Selection.

Rice blast, caused by , is one of the main rice diseases worldwide. The pyramiding of blast-resistance () genes, coupled to Marker-Assisted BackCrossing (MABC), provides broad-spectrum and potentially durable resistance while limiting the donor genome in the background of an elite cultivar. In this work, MABC coupled to foreground and background selections based on KASP marker assays has been applied to introgress four genes (, and ) in a renowned Italian rice variety, highly susceptible to blast.

A fully defined matrix to support a pluripotent stem cell derived multi-cell-liver steatohepatitis and fibrosis model.

Chronic liver injury, as observed in non-alcoholic steatohepatitis (NASH), progressive fibrosis, and cirrhosis, remains poorly treatable. Steatohepatitis causes hepatocyte loss in part by a direct lipotoxic insult, which is amplified by derangements in the non-parenchymal cellular (NPC) interactive network wherein hepatocytes reside, including, hepatic stellate cells, liver sinusoidal endothelial cells and liver macrophages. To create an in vitro culture model encompassing all these cells, that allows studying liver steatosis, inflammation and fibrosis caused by NASH, we here developed a fully defined hydrogel microenvironment, termed hepatocyte maturation (HepMat) gel, that supports maturation and maintenance of pluripotent stem cell (PSC) derived hepatocyte- and NPC-like cells for at least one month.
