Do cells in the body stay in one place once they have found their position?

AI Thread Summary
Cells generally remain in their designated locations once they have established connections with neighboring cells, particularly in mature tissues. During embryonic development, however, significant cell movement occurs, such as during vertebrate gastrulation, where cells migrate to form the three primary germ layers. Neural crest cells also exhibit extensive migration to develop various body structures. Immune cells are notable exceptions, as they actively wander throughout the body to identify and respond to foreign entities. Neurons also demonstrate movement, with their axons and dendrites extending from cell bodies through growth cones, maintaining connections while migrating. In contrast, established cells, like skin cells, do not randomly relocate; such behavior is typically associated with cancer cells undergoing epithelial-mesenchymal transition, allowing them to detach and invade other tissues. Cell adhesion plays a critical role in maintaining cellular positioning and signaling, with cytoskeletal anchors providing structural support.

Once cells in the body "find their place" between other neighboring cells, do they stay there touching each other in the same way or do they move around, migrating, sliding around with their membranes? Can a cell just "take off"?
I wonder the same about neuron cells and their axons and dendrites connections.
Any research out there on this that anyone knows of?
I appreciate any thoughts!

Well my opinion if the cell fits the place because it was functioned to fit in there, then the cells will stay.
Correct me if I'm wrong
 
Generally cells stay put.
However, during vertebrate gastrulation (in embryonic development), lots of cells move around. These movements set up the three primary embryonic layers (endoderm, mesoderm, and ectoderm). These movements are often movements of masses of cells where most of the cells stay near most of their neighbors.

When the neural plate (CNS precursor) is set-up, the neural crest cells form. They can migrate extensively and form a large number of derivatives throughout the body.

Many immune cells, also wander all over the body looking for things that don't belong in the body.

Some neuron cell bodies also migrate (such as cerebellar granular cells, trochlear nerve motor neurons).
Neuron axons and dendrites also migrate away from their cell body, while retaining a connection to it. They use growth cones to do this which are kind of like mini-moving cells.

One of the interesting properties of cancer cells is that they undergo something called epithelial-mesenchymal transition (EMT), where their cell-cell adhesion properties change. There is a lot of interest in this area because when the cancer cells loose this adhesion they can migrate out of the tumour and invade other areas (metatstasis).

Thanks for all your responses!

Basically, unless the cell is in development, or coded to move around due to its role in the organism, or if it is a cancerous cell invading the body, many cells, once they are developed tend to stay where they were assigned to stay.

And thanks for the cell adhesion reference, sounds like once that adhesion is in place, it is essential to signal transduction for the cells. Additionally, cytoskeleton anchors seem to also keep things in place.

All in all, it doesn't sound like, for example, a skin cell would just randomly decide to move down the finger and "decide" to continue its healthy functioning on the neighboring knuckle. This seems to be more of an unhealthy, cancerous behavior for an established cell in a body.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
