Tissue Biopsy under the Microscope

A biopsy is a way for a doctor to diagnose a disease. A sample of tissue or cells is removed from the patient by a doctor and sent to a pathologist to be examined under the microscope.

The following images were captured under a pathology microscope during a tissue biopsy.

Understanding Kidney Disease in Dogs

Kidney failure can cause of death in dogs and there are a number of different ways that kidney disease takes shape in dogs. Veterinarians use a microscope to test for some of the following problems in dogs:
  • Glomerular Disease: This is damage to the kidney filters and can be caused by infections such as Lyme disease or cancer.
  • Pyelonephritis: This is an infection of kidney tissues. If a veterinarian finds this infection, the bacteria that is causing the inflammation of kidney tissues can often be killed.
  • Neophrolithiasis: These are kidney stones. Unlike in humans, kidney stones actually do not typically cause dogs too much pain in the early stages.
  • Ureteral Obstruction with Hydronephrosis: This is a kidney blockage. If a dog has kidney stones and they fragment, they can cause a kidney blockage that will not allow urine to pass and the kidneys will swell and become damaged.
  • Tubulointerstitial Disease: This is damage to kidney tabules, often with an unknown cause. This type of kidney disease can only be determined by using a microscope to examine a kidney biopsy (see image below). 
  • Leptospirosis: This is a bacterial infection and can cause kidney disease along with organ problems in both people and dogs. Infection can be caused by contact with urine or other bodily fluids from the infected dog.
  • Toxins: These are medications, household chemicals, and even ordinary food like grapes or raisins. If your pet ingests toxins contact ASPCA Poison Control immediately.
  • Cancer: The good news is that kidney cancer is not common in dogs. The bad news is that treatment options for kidney cancer in dogs is quite limited. If only one kidney is affected it can be removed with a positive outcome. If the cancer is benign or has not spread the outcome can be good as well.
  • Amyloidosis: This is a protein issue with the kidneys where protein deposits replace normal tissue. 
  • Hereditary: Some purebred dogs have a higher rate of kidney disease than others. Additionally, some young dogs will fail to develop normal kidneys.
The image below is of a dog kidney and was captured using a veterinary lab microscope with a microscope camera.

Lily of the Valley under the Microscope

Convallaria is a genus of flowering plants and includes Lily of the Valley. This is a plant that is sweetly scented and highly poisonous and is native throughout the cool temperate Northern Hemisphere in Asia and Europe.

Convallaria majalis is an herbaceous perennial plant that forms extensive colonies by spreading underground stems and rhizomes.

The images below of Convallaria were captured using the Zeiss Primostar microscope.

Chromosomes under the Microscope

A chromosome is a DNA molecule with part or all of the genetic material of an organism. Chromosomes are only visible under a light microscope when the cell is undergoing the metaphase of cell division. During metaphase, when a chromosome is in its most condensed state, the X-shape structure is called a metaphase chromosome.

The images below were captured under the Zeiss Primostar microscope.

Muscle under the Microscope

The human body has 3 types of muscle in it:
  • Skeletal muscle
  • Smooth muscle
  • Cardiac muscle
Skeletal muscle covers the skeleton and gives the body shape. Skeletal muscle is the type of muscle that is most often thought of when the term "muscle" is used.

Microscopy image of smooth muscle.Smooth muscle (shown at left) is found in walls of hollow organs such as the stomach. Smooth muscle tissue tends to demonstrate greater elasticity than other muscles. It is also found in the urinary tract and digestive tract.







Cardiac muscle is only found in the heart and it is different from the other muscles in the body because it does not get tired. Learn more about the human cardiac muscle here.

Each of the 3 types of muscles in the human body plays an important function in every day life. To learn more about healthy muscles and the roles they play in the human body visit NIH here.

Marmalade Hoverfly under the Microscope Lens

Harald K. Andersen of Steinberg, Norway captured the image below of a marmalade hoverfly. His setup included using the Mitutoyo M Plan Apo 5x Objective lens, connected to his Canon EOS 7D camera.

The marmalade hoverfly (Episyrphus balteatus) is a relatively small hoverfly of the Syrphidae family, widespread through the Palaearctic region which covers Europe, North Asia and North Africa. The upper side of the abdomen is patterned with orange and black bands. These insects often form dense migratory swarms, which may cause panic among people for their resemblance to wasps.

Harald captured this image using a 100 image stack (Canon EF 70-200 f/2.8).
