E.g. you cut yourself in the finger. The cells seems to know they will become part of your finger.
(No lung tissue will be formed in your finger)

It is unfortunate that so many clinicians follow pseudoscience.I am left with the explanation that I heard within the oral tradition of medicine created by pragmatic clinicians rather than the academic scientists of medicine. This simply attributes the control of cellular differentiation to the mysterious abstract mind, as if it contains a map of how the body should be and also uses this as an explanation for placebo effects, pain and certain bizarre phantom limb effects that are occasionally seen in clinical practice but unreported because they can only be explained by such unscientific, abstract models.
The program comes from proteins that are able to bind the DNA and activate or repress transcription. A lot is known about it, researchers in Japan are able to create different brain cells by sequentially exposing induced pluripotent cells with such proteins. The clues on what order to present the proteins came from normal brain development: just look in what order they are expressed normally.Simon Bridge said:Monique's "they are programmed to" does beg the question "where did the program come from?"
The process of cell placement in the body is called cell differentiation. During development, cells are exposed to chemical signals that determine their fate and function. These signals are produced by neighboring cells and the extracellular matrix, guiding the cell to its proper location.
The function of a cell is determined by its specific type and location in the body. This is controlled by the expression of different genes within the cell, which are regulated by various internal and external factors. Additionally, neighboring cells and the extracellular matrix also play a role in controlling a cell's function.
A cell's function is determined by its genetic makeup and the specific signals it receives from its environment. During development, cells are exposed to different signals that result in the expression of certain genes and the development of specific structures and functions. This process is known as cell differentiation.
In some cases, a cell can change its function through a process called transdifferentiation. This occurs when a mature cell is reprogrammed to take on the characteristics and functions of a different type of cell. However, this process is not well understood and is not a common occurrence in the body.
Cells maintain their proper place and function through various mechanisms such as cell signaling, gene expression, and cell-to-cell communication. These processes are constantly monitored and regulated to ensure the proper functioning of the body's tissues and organs. Additionally, the body has mechanisms in place to repair or replace damaged or dysfunctional cells to maintain overall health and function.
