Interestingly, a previous clinical study observed that the atrophy of RPE cells surrounding the optic disc in type 1 diabetic children were significantly less pronounced compared to normal children, contradicting current reports. In order to explore the molecular mechanisms behind this contradictory phenomenon, we conducted a series of experiments and reached the following results. First, RPE cells proliferation increased in a glucose concentration-dependent manner in vitro, accompanied by elevated Brachyury and CTGF protein expression, but decreased overall cell viability. Secondly, in vitro experiments and diabetes mouse models confirmed that insulin promoted RPE cell proliferation in high glucose concentrations by activating ERK1/2 phosphorylation. Furthermore, insulin down-regulated the expression of Brachyury and CTGF proteins, possibly reducing high-glucose‒induced damage to RPE cells. In conclusion, the effect of insulin treatment on the proliferation of RPE cells was significantly more significant than that of hyperglycemia, which may be related to the activation of Erk1/2 or reduction of RPE cell damage by inhibiting the occurrence of EMT.","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"135-145"},"PeriodicalIF":1.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144078431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed cell proliferation rates, white blood cell components, and a limited number of nuclear, cytoplasmic, and membrane markers using immunohistochemistry (IHC) assays on formalin-fixed and paraffin-embedded benign and glial tumor tissue samples from the CNS. It was observed that glioma tissues had increased rates of glial cell proliferation and significant increases in the number of observed T-lymphocytes and granulocytes but decreased expression of markers Somatostatin receptor 2 (SSTR2), L1 cell adhesion molecule (L1CAM), and GATA binding protein 3 (GATA3) when compared to benign tissue samples.

Low-magnitude high-frequency vibration (LMHFV) is a non-invasive biophysical intervention. It has been reported that it exhibits protective effects on high glucose-induced osteoblast dysfunction, but little was known on diabetic vascular complications. In this work, we aim to clarify the role of LMHFV on high glucose-induced endothelial dysfunction and hypothesized that the protective effects functioned through adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway. We cultured primary murine aortic endothelial cells (MAECs) in normal or HG medium, respectively, before exposing to LMHFV. The tube formation, paracellular permeability assay, and aortic ring sprouting assay showed that the high glucose injured-function of MAECs was improved after LMHFV treatment. The intracellular ROS generation analysis, mitochondrial complex I activities measurement, ATP measurement and mitochondrial membrane potential (MMP), and mitochondrial ROS generation analysis of MAECs indicated that mitochondrial function was restored by LMHFV loading in a high glucose environment. Mechanically, western blot assays showed that AMPK phosphorylation was promoted and mTOR was inhibited in LMHFV-induced endothelial function restoration. After the administration of the AMPK inhibitor, Compound C, these protective effects resulting from LMHFV are reversed. These findings suggest that LMHFV plays a significant role in protecting endothelial cells' function and mitochondrial function in high glucose-induced injured MAECs via AMPK/mTOR signalling.","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"82-92"},"PeriodicalIF":0.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organoids are typically cultured in a 3D format within an extracellular matrix and, at the end of an experiment, can be further processed for various cellular or molecular readouts. Analysis often relies on whole mount immunolabeling for markers of interest, which consumes the entire sample/well, thereby limiting sample availability for downstream assays. In addition, 3D cultures become more friable after fixation and are susceptible to sample loss during washing steps. In contrast, by fixing and processing organoids to a paraffin block, dozens or hundreds of unstained slides can be generated, enabling robust characterization via multiple assays, including histologic evaluation and (immuno)histochemical stains, thus maximizing the yield of these time- and labor-intensive cultures. Here we describe three methods to process 3D Matrigel cultures into paraffin blocks using Histogel as an embedding agent. The three techniques all yield high-quality sections but vary in complexity of implementation at different steps, and their application for different use cases is discussed.","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"46-57"},"PeriodicalIF":0.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors investigated the challenges of working with plant tissues by collecting various flora to represent the four main plant organs: leaf, stem, root, and flower/fruit. Triplicate samples for each specimen were placed into formalin for paraffin embedding, placed into formalin for later frozen sections, and used fresh to undergo immediate frozen sectioning. Frozen sections of plant tissues were more difficult to obtain than formalin-fixed paraffin-embedded (FFPE) sections, exhibited tissue loss during staining, and were inferior morphologically to FFPE sections. Although, historically, plant tissue fixation and processing has employed several different reagents compared with those used in animal tissue processing and took significantly longer times, the current investigation determined reagents and protocols from a modern histology laboratory which processes mammalian tissues can be applied to plant tissue processing with only slight modifications in respect to reagent timing. Additionally, staining techniques were compared and while it is well known that plant cell walls stain well with safranin O, the current investigation determined the uptake of safranin O can be accelerated by incubating at 60°C.","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"58-67"},"PeriodicalIF":0.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142120024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
