Which type of cells are considered most radiosensitive according to the Bergonie-Tribondeau law?

The Bergonie-Tribondeau law states that the radiosensitivity of cells is directly related to their reproduction rate and inversely related to their degree of differentiation. According to this principle, embryonic tissue cells are considered the most radiosensitive. These cells are typically immature and rapidly dividing, which makes them more susceptible to damage from radiation.

During the early stages of development, cells are undifferentiated and have a high mitotic rate, meaning they are constantly dividing and have a greater chance of encountering radiation. This rapid division, combined with their simplistic structure, leaves them more vulnerable to the effects of radiation, which can lead to significant biological damage.

In contrast, blood cells, skin cells, and muscle cells have different levels of radiosensitivity due to their characteristics and functions. While blood cells and skin cells are also sensitive to radiation, they are relatively more differentiated than embryonic tissue cells, making them somewhat less sensitive according to the Bergonie-Tribondeau law. Muscle cells, being highly differentiated and having a very low mitotic rate, are even less radiosensitive compared to the other cell types mentioned. Thus, embryonic tissue cells stand out as the most radiosensitive according to this law.
