Sertoli cells secrete cathepsin L which participates in spermatozoa production and maturation in testis and epididymis. Sertoli cells also regulate activity of regulatory T cells, helper T cells and cytotoxic T cells to prevent autoimmune attack on developing spermatogenic cells. Mast cells and activated T cells were first cells identified to express CTLA-2 alpha. CTLA-2 alpha mRNA is expressed by undifferentiated spermatogonia but its protein has never been demonstrated in testis, not even in other male reproductive organs. This study therefore aimed at investigating by immunohistochemistry CTLA-2 alpha localization in testis, rete testis, efferent duct, epididymis, deferens duct, seminal vesicles and prostate. Results showed localization of CTLA-2 alpha in Leydig cells, Sertoli cells, spermatogonia, spermatocytes, spermatids and spermatozoa, as well as in epithelial cells lining rete testis, efferent ducts, epididymis including spermatozoa, deferens duct and prostatic urethra. Basal cells and principal cells of initial segment of epididymis showed weak staining. In accessory sex glands, staining was detected in apical portion of cytoplasm of epithelial cells lining seminal vesicles. In prostate, staining was diffusely distributed in cytoplasm of luminal epithelial cells. Extension of prostate cell apical cytoplasm into lumen was frequently encountered in anterior and dorsal prostate, representing apocrine release of secretory products. Localization of CTLA-2 alpha in male reproductive system is suggestive of its potential roles in regulation of spermatogenesis in testicular tissues, maturation of spermatozoa in tubular structures and secretion of proteins and peptides by seminal vesicles and prostate essential for male fertility.</p>\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"55 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147678248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the radial artery dimensions in thirty adult body donors housed in the Department of Clinical Anatomy, University of KwaZulu-Natal, Durban, South Africa. The external and internal diameters, along with wall thickness of the radial artery, were measured at three anatomical sites viz. the point of origin, at the wrist joint and in the anatomical snuffbox bilaterally using a digital vernier calliper in sixty upper limb specimens (BREC/00006978/2024). There was a progressive distal tapering pattern, with the external diameters of the radial artery decreasing from its point of origin to the anatomical snuffbox. The internal diameter of the radial artery was 2.98 ± 0.76 mm at the origin, 2.20 ± 0.75 mm at the wrist joint and 1.75 ± 0.69 mm in the anatomical snuffbox. The wall thickness of the radial artery also decreased distally, from its point of origin to the anatomical snuffbox. There were no statistically significant differences between biological sex or laterality. The internal radial artery diameters suggest that a 5 French (5Fr) sheath may be suitable in 32% of upper limbs at the wrist and in 38% of upper limbs in the anatomical snuffbox.

MRI can provide valuable information, but detailed descriptions of normal MRI anatomy in the European pond turtle (<i>Emys orbicularis</i>) are limited. To document how the non-respiratory coelomic organs of adult female <i>Emys orbicularis</i> appear on MRI and where they are located within the coelomic cavity. Ten adult females were examined using a 3-Tesla MRI scanner with T1- and T2-weighted transverse, sagittal, and dorsal sequences. Organs were identified based on their signal characteristics and anatomic position, and findings were compared with published anatomical studies in chelonians. MRI provided clear visualisation of the heart, major vessels, liver, gallbladder, gastrointestinal tract, spleen, kidneys, urinary bladder and reproductive tissues. All ventricular components including the cavum pulmonale, cavum venosum, cavum arteriosum, muscular ridge, and interventricular canal were consistently identified. Two separate hepatic veins (right and left) drained into the sinus venosus, which differs from patterns reported in several other turtle species. The right and left lateral abdominal veins joined near the midline to form a common vessel before entering the left hepatic lobe. The spleen was positioned on the right side of the coelomic cavity, ventral to the lung. The pancreas could not be distinguished due to similar signal intensity to the liver. The arrangement of the jejunum and ileum showed notable differences compared with other freshwater and marine turtles. This study provides the first clear MRI guide to the non-respiratory coelomic organs in female <i>Emys orbicularis</i>. These observations can help veterinarians interpret routine MRI exams and better identify disorders involving the gut, reproductive tract, vessels and urinary system. Studies that include contrast media or anatomical dissection are still needed to fully define the vascular pattern and the pancreas.</p>\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"55 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147647307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LM showed H&amp;E-stained neuromasts as pale, spherical structures in the gill epithelium. PAS (Periodic Acid-Schiff) staining showed modest neuromast reactivity but substantial goblet cell and microvilli glycocalyx positivity, while bromophenol blue showed high sensory cell protein content. The neuromast had sensory hair cells, a mantle, supporting cells, and basal cells. The neuromast center contained sensory hair cells and supporting cells. Mantle cells formed the outer sheath. Neuromast basal cells were at the bottom. The basal neuromast nerve terminal extends upward to innervate the sensory hair cells. The afferent nerve terminal had several secretory vesicles. Afferent nerve terminals were myelinated in the basal neuromast and lost their myelin sheath in the apex. The lamina propria efferent nerve terminal was partially myelinated. Prolongations identified telocytes in light microscopy by Toluidine blue, methylene blue and iron haematoxylin. They were linked to the neuromast nerve terminal. Telocyte cell bodies and podomeres were detected by TEM. They touched afferent and efferent nerve terminals. The surprise detection of CD3 and mAb 3A5 positivity in gill neuromast sensory hair cells indicates a novel, non-immunological function for this established T-cell marker and suggests an important connection between the immune and sensory systems. In conclusion, gill-associated neuromasts may detect the water stream entering the gills to adjust respiratory rates. Telocytes may regulate neuromast function.</p>\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"55 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study characterised postnatal growth and structural changes of the thoracic cage during the first year of life and evaluated sex-related differences in growth trajectories. A total of 120 clinically healthy, full-term calves (60 males, 60 females) were enrolled within 24 h after birth and examined at birth and at 1, 3, 6, 9 and 12 months of age. Morphometric measurements included body weight, thoracic circumference, thoracic depth and thoracic width. Thoracic shape was assessed using the thoracic index (TW/TD × 100) and the costal curvature ratio (TW/TC). Longitudinal changes were analysed using linear mixed-effects models. All thoracic dimensions increased significantly with age (<i>p</i> &lt; 0.001). Thoracic circumference increased from 72.1 ± 3.4 cm at birth to 140.6 ± 7.8 cm at 12 months. Significant age × sex interactions were observed for body weight and thoracic circumference (<i>p</i> &lt; 0.01), with males showing greater transverse thoracic expansion after 6 months. The thoracic index increased progressively (<i>p</i> &lt; 0.001), indicating proportionally greater growth in width than in depth, whereas the costal curvature ratio remained relatively stable. Strong positive correlations were found between body weight and thoracic measurements (<i>r</i> = 0.92–0.96; <i>p</i> &lt; 0.001). These data provide reference values for early thoracic development and demonstrate the emergence of sexual dimorphism in thoracic morphology during the first postnatal year.</p>\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"55 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
