Stromal cells, or mesenchymal stromal cells, are differentiating cells found in abundance within bone marrow but can also be seen all around the body. Stromal cells can become connective tissue cells of any organ , for example in the uterine mucosa ( endometrium ), prostate , bone marrow , lymph node and the ovary .
Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.
Pyelonephritis is inflammation that results from a urinary tract infection that reaches the renal pelvis of the kidney. [6] Lupus nephritis is inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease of the immune system. [7] Athletic nephritis is nephritis resulting from strenuous exercise.

This filtrate then flows along the length of the nephron, which is a tubular structure lined by a single layer of specialized cells and surrounded by capillaries. The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the secretion of wastes from the blood into the urine.
The intercalated A cells are stimulated when the body is experiencing acidic conditions. Under acidic conditions, the high concentration of CO 2 in the blood creates a gradient for CO 2 to move into the cell and push the reaction HCO 3 + H ↔ H 2 CO 3 ↔ CO 2 + H 2 O to the left. On the luminal side of the cell there is a H + pump and a H
The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule. The renal tubule extends from the capsule.
The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism.
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome.The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids.
