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

In summary, cells in the body typically stay in their designated place once they have been developed. However, during vertebrate gastrulation, cells may move around to set up the primary embryonic layers. Some cells, such as immune cells and certain neuron cells, may also migrate in order to perform their designated functions. Cancer cells may also undergo a change in cell-cell adhesion, allowing them to invade other areas of the body. Overall, established cells in the body do not typically move around unless it is part of their normal function or due to an unhealthy process such as cancer.

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.

1. Do all cells migrate in a body?

Yes, all cells have the ability to migrate in the body. This is an essential process for various biological functions such as wound healing, tissue repair, and immune response.

2. What factors influence cell migration?

There are several factors that can influence cell migration, including chemical signals, physical cues, and cellular interactions. Chemical signals, such as growth factors and hormones, can attract or repel cells towards or away from a specific location. Physical cues, such as the composition and stiffness of the extracellular matrix, can also affect cell movement. Additionally, interactions with other cells can play a role in directing cell migration.

3. How do cells migrate in the body?

Cells can migrate in the body through various mechanisms, including amoeboid movement, mesenchymal movement, and collective cell migration. Amoeboid movement involves cells changing their shape and using protrusions to move forward. Mesenchymal movement involves cells elongating and contracting to move through tissue. Collective cell migration involves groups of cells moving together as a cohesive unit.

4. Can cell migration go wrong?

Yes, cell migration can go wrong and lead to various diseases and disorders. For example, abnormal cell migration can contribute to cancer metastasis and autoimmune diseases. In some cases, cells may migrate to the wrong location, leading to developmental defects or abnormal tissue growth.

5. Is cell migration a continuous process?

Yes, cell migration is a continuous process in the body. Cells are constantly moving and changing positions to maintain tissue homeostasis and respond to various stimuli. However, the rate and direction of cell migration can vary depending on the specific biological process and the surrounding environment.
