Why are younger cells more radiosensitive?

It is widely believed that human radiosensitivity increases with age due to an increase of oxidative stress, telomere attrition, a decline in DNA damage response efficiency and inflammatory response [1, 2].

Are lymphocytes the most radiosensitive?

Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers. Very sensitive cells are also oocytes and lymphocytes, although they are resting cells and do not meet the criteria described above.

Are lymphocytes sensitive to radiation?

Peripheral blood and thoracic duct lymphocytes are sensitive to irradiation. However, a distinct population of resistant lymphocytes exists, which is characterized by reactivity to a very low dose of lymphocyte-stimulating lectins in vitro.

Why are some cells more radiosensitive?

Actively dividing cells that are less differentiated tend to show higher radiosensitivity. For example, hematopoietic stem cells in bone marrow are differentiated into various blood cells, while dividing actively.

What is the most radiosensitive tissue?

From these discussions we can conclude that Bone marrow is the most radiosensitive tissue of the body.

What tissue is most radiosensitive?

Bone marrow
From these discussions we can conclude that Bone marrow is the most radiosensitive tissue of the body.

What tissues are most sensitive to radiation?

Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive. Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive. The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells.

Which of the following types of blood cells is the most sensitive to radiation?

Which of the following types of blood cells is the most sensitive to radiation? Lymphocytes are white or colorless blood cells derived from lymphatic tissues. Because of their rapid cell division they are more susceptible to the affects of radiation.

What part of the cell is most sensitive to radiation?

Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive. Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive.

What are radiosensitive cells?

Radiosensitivity is the relative susceptibility of cells, tissues, organs, organisms, or other substances to the injurious action of radiation. The most radio-sensitive cells are those which: have a high division rate. have a high metabolic rate.
