Waldeyer's Rule

Waldeyer's Rule is a law that establishes a relationship between the rate of tissue growth and its specific ability to divide. This rule was formulated in 1901 by the German physiologist Waldeyer.

Waldeyer's rule describes that the growth rate of a tissue depends on its ability to divide, that is, on how many cells divide per unit time. If the ability to divide is high, the tissue will grow quickly, and vice versa.

Waldeyer's rule is important for understanding the processes of tissue growth and regeneration in the body. It allows us to understand how cells divide and grow, and how different tissues interact with each other. In addition, this rule is used in medicine to develop new methods for treating diseases associated with impaired cell growth and division.

One example of the application of Waldeyer's rule is hair growth. Hair grows due to the division of hair follicle cells, which are located in the scalp. The more cells divide, the faster the hair grows. However, if the ability to divide decreases, for example due to aging or illness, then hair begins to fall out and grows more slowly.

Thus, Waldeyer's rule is an important tool for understanding the processes of tissue growth and their regulation in the body. It can help develop new treatments for various diseases associated with disorders of cell growth and division.

Waldeyer's rule - discovered in 1932, named after the scientist Andreas Waldeyer, which describes a set of cells that provide and regulate the action of all other cells of the body or organ. Cells that are included in the expression of the Waldeyer marker express it with different intensities. This unevenness of expression causes the formation of areas of high, low and moderate expression of the Valdeir marker. Depending on which cell predominates in a given region, these regions are divided into cells of high, moderate and low expression. Examples of these areas are the cambial zones of epithelial tissue, the basement membrane of the vascular endothelium, where nerve cells are located singly, and the axons of peripheral neurotransmitters formed from the cambial zones of nervous tissue. The rule is experimentally confirmed in all types of animals: guinea pig, mouse, rat, dog, rabbit, but the largest number of studies are devoted to studying the rule in humans.
