Types of Cuboidal Cells
When it comes to the classification of cells, cuboidal cells are one of the most commonly studied type of cells. Cuboidal cells, as the name implies, are box-shaped cells with six square or rectangular sides. They can form a single layer in some tissues or can be arranged in a stack to form a multilayered tissue. Cuboidal cells are important because they make up various organs in our body such as the kidneys, liver, and glands.
Shapes of Cuboidal Cells
- Simple cuboidal cells: These cells are single-layered and cube-shaped with centrally located nuclei. They mainly act as protective barriers, aid in secretion, and diffusion of substances across them. Examples include the lining of renal tubules and the secretory cells in glands.
- Transitional cuboidal cells: These cells are found in the lining of the urinary bladder. They are square in shape when the bladder is empty, but become more elongated and flattened when it is full. This allows the bladder to expand and hold an increased volume of urine.
- Stratified cuboidal cells: These cells are typically arranged in multiple layers, and the apical layer of cells is made up of cube-shaped cells. Stratified cuboidal cells are generally found lining large excretory ducts of some glands such as mammary and sweat glands.
Functions of Cuboidal Cells
Cuboidal cells perform several functions depending on their location in the body. In the kidney, cuboidal cells lining renal tubules help in the reabsorption of water and other substances back into the bloodstream. Cuboidal cells lining salivary glands, pancreas, and other organs also help in secetion of their respective fluids.
Below is a table that summarizes the different types of cuboidal cells and their functions.
| Type of Cuboidal Cells | Location | Function |
|---|---|---|
| Simple cuboidal cells | Lining of renal tubules, secretory cells in glands | Protection, secretion, and diffusion of substances |

Diseases associated with Cuboidal Cells.
Cuboidal cells are epithelial cells that have a cuboidal shape, meaning they are approximately as tall as they are wide. These cells are found in many parts of the body, including the kidneys, liver, and lungs, where they serve important functions such as secretion, absorption, and protection. However, when these cells become abnormal or grow uncontrollably, they can lead to a variety of diseases and health issues.
Here are seven diseases associated with cuboidal cells:
- Polycystic kidney disease (PKD) – This is a genetic disorder that causes clusters of cysts to form in the kidneys, which are made up of cuboidal cells. These cysts can grow and multiply over time, eventually leading to kidney damage and failure.
- Polycystic liver disease (PLD) – This is a rare condition that is similar to PKD, but affects the liver instead of the kidneys. In PLD, clusters of cysts form in the liver, which is also composed of cuboidal cells. This can cause liver enlargement, abdominal pain, and other symptoms.
- Lung adenocarcinoma – This is a type of lung cancer that arises from the cuboidal cells that line the air sacs in the lungs. Adenocarcinomas tend to grow and spread more slowly than other types of lung cancer, but can still be very dangerous if left untreated.
- Biliary atresia – This is a rare liver disease that affects infants, causing the bile ducts (which are lined with cuboidal cells) to become blocked and damaged. This can lead to liver damage and failure if not treated promptly.
- Cystic fibrosis (CF) – CF is a genetic disorder that affects many different parts of the body, including the lungs, pancreas, and digestive system. In the lungs, CF can cause thick mucus to build up and clog the airways, which can lead to breathing problems and lung infections. Cuboidal cells in the lungs are affected by this disease.
- Nephrotic syndrome – This is a group of symptoms that occur when the kidneys (which are lined with cuboidal cells) are damaged and are not able to properly filter waste products from the blood. This can cause protein to leak into the urine, leading to edema (swelling) in various parts of the body.
- Cholangiocarcinoma – This is a type of liver cancer that arises from the cells lining the bile ducts in the liver, which are cuboidal in shape. This is a rare and aggressive form of cancer that can be difficult to treat.
Diagnostic methods of diseases associated with cuboidal cells
Testing for diseases associated with cuboidal cells typically involves a combination of medical history, physical examination, imaging tests (such as ultrasounds or CT scans), and blood or urine tests. A biopsy may also be performed, which involves removing a small sample of tissue from the affected area for examination under a microscope.
Treatment of diseases associated with cuboidal cells
Treatment for diseases associated with cuboidal cells depends on the specific condition and its severity, but may involve medications, surgery, or other interventions. For example, PKD may be managed with blood pressure medication and lifestyle changes, while PLD may require surgical removal of some or all of the affected liver. Lung adenocarcinoma may be treated with surgery, radiation therapy, and/or chemotherapy, depending on the stage and location of the cancer.
Conclusion
