Prof. Taija Mäkinen, PhD Uppsala University Department of Immunology, Genetics and Pathology Division of Vascular Biology ABSTRACT Chronic kidney disease (CKD) is a major health problem and an economical burden affecting people worldwide. The main causes of CKD are diabetes and hypertension and patient numbers keep increasing. In many cases, CKD is progressive leading to end stage renal disease (ESRD), a condition that can be treated only through chronic dialysis or renal transplantation. -

Urinary System
URINARY SYSTEM Ján Líška DVM, PhD Institut of Histology and Embryology, Faculty of Medicine, Comenius University Urinary system • The kidneys are the organ with multiple functions: • filtration of the blood • excretion of metabolic waste products and related removal of toxins • maintenance blood volume • regulation of acid-base balance • regulation of fluid and electrolyte balance • production of the hormones The other components of urinary system are accessory. Their function is essentially in order to eliminate urine. Urinary system - anatomy • Kidney are located in the retroperitoneal space • The surface of the kidney is covered by a fibrous capsule of dense connective tissue. • This capsule is coated with adipose capsule. • Each kidney is attached to a ureter, which carries urine to the bladder and urine is discharged out through the urethra. ANATOMIC STRUCTURE OF THE KIDNEY RENAL LOBES CORTEX outer shell columns Excretory portion medullary rays MEDULLA medullary pyramids HILUM Collecting system blood vessels lymph vessels major calyces nerves RENAL PELVIS minor calyces ureter Cortex is the outer layer surrounding the internal medulla.

They posses papilla - having openings through which urine passes into the calyces.

Lab-Renal-2018-Zw4m.Pdf
Introduction The slides for this lab are located in the “Urinary System” folders on the Virtual Microscope. In this lab, you will learn about the structures within the kidney required to filter the blood and the tubes required to transport the resulting waste products outside the body. The journey begins in the unit of the kidney called the nephron. Here the blood is filtered, products are reabsorbed and then some are secreted again, based on the body’s current state. Dissolved in water, these products then travel through the conducting portion of the kidney to the ureters. The ureters insert on the urinary bladder obliquely and posteriorly. The urinary bladder temporarily stores urine until it can be conveniently evacuated. Urine exits the body through the urethra. Learning objectives and activities Using the Virtual Slidebox: A Outline a renal lobe and identify the structural components of a renal lobule B Examine the components of the renal corpuscle: glomerulus and Bowman’s capsule C Classify the different areas of the renal tubules based upon their histological appearance and location D Compare the structures of the excretory passageways and use this information to identify them E Complete the self-quiz to test your understanding and master your learning Outline a renal lobe and identify the structural components of a renal lobule Examine Slide 1 and approximate a renal lobe in the kidney by identifying the following: Each kidney can be divided into somewhere between 8-15 renal lobes. Each lobe consists of a medullary pyramid capped by the cortex and flanked by renal columns with a renal papilla at its apex. -
Myofibroblasts Correlate with Lymphatic Microvessel Density and Lymph Node Metastasis in Early-Stage Invasive Colorectal Carcinoma
ANTICANCER RESEARCH 25: 2705-2712 (2005) Myofibroblasts Correlate with Lymphatic Microvessel Density and Lymph Node Metastasis in Early-stage Invasive Colorectal Carcinoma PIN LIANG1, JIAN-WEI HONG2, HIDEYUKI UBUKATA1, GE LIU1, MOTONOBU KATANO1, GYO MOTOHASHI1, TERUHIKO KASUGA1, YOSHINORI WATANABE1, ICHIRO NAKADA1 and TAKAFUMI TABUCHI1 1Fourth Department of Surgery and 2Department of Pathology, Tokyo Medical University Kasumigaura Hospital, Ibaraki, Japan Abstract. Background: Recent studies have shown that the Myofibroblasts are the main component cells in tumor interactions between tumor cells and stromal cells are stroma, and alpha-smooth muscle actin (·-SMA)-positive important in tumor development. A possible correlation myofibroblasts were found to participate in the synthesis of between tumor-activated myofibroblasts, the main component extracellular matrix components of tumor stroma, and to cells of tumor stroma, and lymphatic microvessel density produce lytic enzymes able to degrade the basement (LMVD) or other clinical parameters in carcinoma was membrane surrounding tumor glands. Although present in investigated. Materials and Methods: Immunohistochemical the progressive tumor nodules, they disappear during tumor examination of alpha-smooth muscle actin and podoplanin regression (5, 6). The correlation between microvessel were performed in 83 cases of early-stage invasive colorectal density and myofibroblasts was shown by Zidar et al. (7), but carcinoma. Results: There was a good correlation between the influence of myofibroblasts in lymphagiogenesis remains proliferation of myofibroblasts (PMpt) and LMVD (LMVDpt) unclear. Only recently, podoplanin, a 43-kd glomerular in the peri-tumoral area (p=0.0034). Increased PMpt was also podocyte membrane mucoprotein and a specific lymphatic associated with lymphatic invasion (p=0.0051) and with vessel marker, has enabled the investigation of the lymph node metastasis (p=0.011). -

Proximal convoluted tubule. 11. Arched connecting tubule. through entire medulla). MANY more banks of glomeruli occur in the cortex than are represented on the model, and the proportionate length of the medullary elements has been greatly reduced. The fundamental physiological unit of the kidney is the nephron, consisting of the glomerulus, Bowman's capsule, the proximal convoluted tubule, Henle's loop, and the distal convoluted tubule. The blood is filtered in the glomerulus, water and soluble substances, except blood proteins, passing into Bowman's capsule in the same proportions as they occur in the blood. In the proximal tubule water and certain useful substances are resorbed from the provisional urine, while some further components may be added to it by secretory activity on the part of the tubular epithelium. In the remainder of the tubule, resorption of certain substances is continued, while the urine is concentrated further by withdrawal of water. The finished urine flows through the collecting tubules without further change. Various kinds of loops occur, varying in length of the thin segment, and in the level to which they descend into the medulla. -
Renal Corpuscle Renal System > Histology > Histology
Renal Corpuscle Renal System > Histology > Histology Key Points: • The renal corpuscles lie within the renal cortex; • They comprise the glomerular, aka, Bowman's capsule and capillaries The capsule is a double-layer sac of epithelium: — The outer parietal layer folds upon itself to form the visceral layer. — The inner visceral layer envelops the glomerular capillaries. • As blood passes through the glomerular capillaries, aka, glomerulus, specific components, including water and wastes, are filtered to create ultrafiltrate. • The filtration barrier, which determines ultrafiltrate composition, comprises glomerular capillary endothelia, a basement membrane, and the visceral layer of the glomerular capsule. • Nephron tubules modify the ultrafiltrate to form urine. Overview Diagram: • Tuft of glomerular capillaries; blood enters the capillaries via the afferent arteriole, and exits via efferent arteriole. • The visceral layer of the glomerular capsule envelops the capillaries, then folds outwards to become the parietal layer. • The capsular space lies between the parietal and visceral layers; this space fills with ultrafiltrate. • Vascular pole = where the arterioles pass through the capsule • Urinary pole = where the nephron tubule begins • Distal tubule passes by the afferent arteriole. Details of Capillary and Visceral Layer: • Fenestrated glomerular capillary; fenestrations are small openings, aka, pores, in the endothelium that confer permeability. • Thick basement membrane overlies capillaries • Visceral layer comprises podocytes: — Cell bodies — Cytoplasmic extensions, called primary processes, give rise to secondary foot processes, aka, pedicles. • The pedicles interdigitate to form filtration slits; molecules pass through these slits to form the ultrafiltrate in the 1 / 3 capsular space. • Subpodocyte space; healthy podocytes do not adhere to the basement membrane. Clinical Correlation: • Podocyte injury causes dramatic changes in shape, and, therefore, their ability to filter substances from the blood. -
