Metaplastic cells are differentiated cells that undergo a process called metaplasia, where one type of adult cell is replaced by another type of adult cell, often in response to chronic irritation or injury. This change can occur in various tissues and is typically considered an adaptive response, although it may predispose tissues to dysplasia or cancer if the underlying cause persists. For example, in the respiratory tract, normal columnar epithelial cells may be replaced by squamous cells due to smoking.
What else can I help you with?
Does an annimal cell have a cell wall?
No, insect cell has not a cell wall, insect cell has cell membrane. Only plant cell has cell has cell wall.
Is no cell wall a plant cell or an animal cell?
an animal cell DOES NOT have a cell walla plant cell DOES have a cell wall
What Controls what moves in and out of the cell?
Cell membrane
Cell membrane is what type of cell?
cell membrane is a part of the cell (organelle) not a cell
Does a leaf cell have a cell membrane?
Yes, a leaf cell has a cell membrane. The cell membrane is a protective barrier that surrounds the cell and regulates the movement of substances in and out of the cell. It is an essential structure for the proper functioning of the cell.
Are all metaplastic cells precancerous?
Not necessarily, although in general a metaplastic cell is abnormal. A cell can also be metaplastic due to incomplete differentiation or due to dedifferentiation.
What is the presence of metaplastic cells in a pap smear result?
Metaplasia found on a pap smear result is an indication that sampling was complete. It does not indicate a problem.
What is metaplastic polyp?
A metaplastic polyp is a type of gastrointestinal polyp characterized by the transformation of one type of epithelial cell into another, often in response to chronic irritation or inflammation. These polyps are commonly found in the stomach and can be associated with conditions like chronic gastritis. Metaplastic polyps are generally considered benign but may have the potential for dysplasia in certain contexts. Regular monitoring and histological examination are important for determining their nature and any potential risks.
Is hyalinized leiomyoma with metaplastic ossification a benign condition or a malignant one?
benign
Why is squamous metaplastic cells bad for the lungs of smokers?
Squamous metaplastic cells in the lungs of smokers are indicative of an abnormal response to chronic irritation from tobacco smoke. This cellular change can lead to a loss of normal ciliated respiratory epithelium, impairing the lungs' ability to clear mucus and pathogens, thereby increasing the risk of infections and respiratory diseases. Additionally, these metaplastic cells can be precursors to dysplasia and lung cancer, making their presence a significant concern for smokers' lung health.
What causes metaplastic changes to bronchial epithelial tissue?
Smoking can, or Vitamin A deficiency (since vitamin A is essential for epithelium differentiation)
What cells are enlarged with darkened nuclei and abnormal chromatin?
Cells that are enlarged with darkened nuclei and abnormal chromatin are typically indicative of cancer cells. These abnormal features can be seen in cancerous cells due to uncontrolled cell division and impaired DNA replication and repair mechanisms. It is important to further evaluate these cells for proper diagnosis and treatment.
What does it mean if pap smear results show endocervical and or squamous metaplastic cells are present?
Endocervical and/or squamous cells are normal on a pap smear. This notation on your result means the test was complete.
What is focal tubal metaplasia?
Focal tubal metaplasia is a condition characterized by the abnormal transformation of epithelial cells in the fallopian tubes, often observed in the context of endometriosis or pelvic inflammatory disease. This metaplastic change can result in the replacement of normal tubal epithelium with different cell types, typically as an adaptive response to injury or inflammation. While it is generally considered a benign finding, focal tubal metaplasia may be associated with various gynecological conditions and is sometimes noted in histopathological examinations. Further investigation may be necessary to determine its clinical significance in individual cases.
What are the combination of numbers on the left side and a letter on the top of a spreadsheet that addresses a cell called?

Does an annimal cell have a cell wall?
No, insect cell has not a cell wall, insect cell has cell membrane. Only plant cell has cell has cell wall.
Is no cell wall a plant cell or an animal cell?
an animal cell DOES NOT have a cell walla plant cell DOES have a cell wall
