Pathological stromal changes are believed to cause benign prostatic hyperplasia (BPH). The prostate stromal tissue is known to have several subtypes of interstitial cells that connect the epithelium and smooth muscle. However, the characteristics of their morphology and connection patterns are not fully understood. Therefore, we aimed to investigated the three-dimensional morphology and intercellular interactions of interstitial cells in the prostate ventral lobe of mature wild-type mice using immunohistochemistry and focused ion beam–scanning electron microscopy tomography (FIB–SEM tomography). The prostate interstitial cells exhibited immunohistochemical subtypes, including PDGFRα single-positive, CD34 single-positive, and CD34 and PDGFRα double-positive. PDGFRα single-positive cells were observed as elongated cells just below the epithelium, CD34 single-positive cells were observed as polygonal cells in the area away from the epithelium, and double-positive cells were observed as elongated cells situated slightly deeper than PDGFRα single-positive cells. Furthermore, connexin43-immunoreactive puncta were observed on interstitial cells just beneath the epithelium, suggestive of possible electrical connections among the PDGFRα single-positive interstitial cells. Three-dimensional structural analysis using FIB–SEM tomography revealed sheet-like multilayered interstitial cells that appear to separate the glandular terminal from the deeper interstitial tissue, which includes smooth muscle and capillaries. Further, epithelial cells might be indirectly connected to the smooth muscle and nerve fibers via these sheet-like multilayered interstitial cellular networks. These findings suggest that the cellular network that separates the glandular terminals from the deep interstitial tissue functionally bridges the epithelium and smooth muscle, possibly playing a pivotal role in prostate tissue homeostasis through the epithelial−smooth muscle or epithelial−stromal relationships.</p></div>","PeriodicalId":6961,"journal":{"name":"Acta histochemica","volume":"126 3","pages":"Article 152153"},"PeriodicalIF":2.5,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0065128124000217/pdfft?md5=29f84e630c9a812073b56d284b3365cc&pid=1-s2.0-S0065128124000217-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140123149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, therefore, we conducted molecular level examinations to determine whether pericytes, specialized cell communities situated near blood vessels, could serve as a substitute for human bone marrow-derived mesenchymal stem cells (hBM-MSCs).

Here, we tested the hypothesis that changes to enteric glia, a type of peripheral glia that surround enteric neurons and regulate gut homeostasis, are associated with tumor development and that supplementing with the antioxidant L-glutathione is protective against the changes induced. Immunohistochemistry for neurons, enteric glial cells and immune cells was performed in whole-mount preparations and frozen histological sections of the jejunum from 20 Wistar rats, distributed in 4 groups: control, tumor of Walker-256, control administered with 1 % L-glutathione, and tumor of Walker-256 administered with 1 % L-glutathione.

In contrast, tumors increased glia in the jejunal mucosa and this effect was accompanied by B-lymphocyte recruitment. GSH-supplemented diet was not sufficient to protect against changes to neurons and glia in the submucosal plexus but was partially protective in the myenteric plexus. L-glutathione had no effect on physiological parameters of cachexia but was sufficient to preserve enteric glial cell density in the myenteric plexus.

Sias play determinant roles in a multitude of biological processes in human tissues from development to adult life until aging. In this review, we summarized the current knowledge on the sialylation status in the human testis with a main focus on sexually mature life and aging, when this organ shows significant morphofunctional changes resulting into variations of hormonal levels, as well as changes in molecules involved in mitochondrial function, receptors, and signaling proteins. Evidence suggests that Sias may have crucial morphofunctional roles in the different testicular components during the sexually mature age. With advancing age, significant loss of Sias and/or changes in sialylation status occur in all the testicular components, which seems to contribute to morphofunctional changes characteristic of the aging testis. Based on the current knowledge, further in-depth investigations will be necessary to better understand the mechanistic role of Sias in the biological processes of human testicular tissue and the significance of their changes during the aging process. Future investigations might also contribute to the development of novel prophylactic and/or therapeutic approaches that, by maintaining/restoring the correct sialylation status, could help in slowing down the testis aging process, thus preserving the testicular structure and functionality and preventing age-related pathologies.</p></div>","PeriodicalId":6961,"journal":{"name":"Acta histochemica","volume":"126 2","pages":"Article 152143"},"PeriodicalIF":2.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0065128124000114/pdfft?md5=79530fcb96333c28d6f438e3f409f08a&pid=1-s2.0-S0065128124000114-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139915328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mRNA expression of DDX3Y was not affected by USP9Y overexpression, while its protein levels were significantly up-regulated in USP9Y overexpressed LC cells.
