What is the skin stem cells function?

Answer 1

Skin is primarily a physical barrier that keeps the outside world 'out' (protection) and the inside tissue 'in' (homeostasis). It also serves to control moisture (hydration), temperature, sensation, mechanical damage (healing), excretion and gas exchange. It also serves as a home to most the microorganisms that we host! These non-threatening 'bugs' stop the nasty bugs from infecting (colonizing) us, feed off our excretions and also provide some limited protection from radiation and mechanical injury.

Answer 2

1- Protection of the body against virulent organisms ("germs") and disease by acting as a first defense against disease-causing particles, because most can't get through unopened skin)

2- maintaining normal body temperature. (blood vessels in the skin can help to hold or release heat maintaining a constant temperature)

3- working as a sense organ (specialized nerve cells sense and relay info to the brain)

4- preventing the loss of water from the body.

5- excretion of waste by sweating. (sweat glands in the skin release waste in the sweat)

6- mechanical support of the body

7- protection of the body against dangerous UV rays

8- production of vitamin D (formed by ultraviolet light in fat molecules in your epidermis)

9- Langerhans cells working as an immune defense mechanism.

10- As an external shape, it helps humans in recognizing each other.It keeps germs out of the body,
to protect the body from foreign elements
We have skin so bacteria and germs keep out of our body and so we keep our blood, tissues and guts from spilling out of our body.
Skin is very important to the human body because it protects everything in the inside of your body. Skin protects all of your veins, blood vessels, arteries, and tissue. Skin is also a water proof covering that keeps you cool in the hot, and moderates your temperature. The three layers of the skin are the epidermis, dermis and subcutaneous layer. It's important to protect your skin from the sun; so you do not skin cancer. If you protect your skin, you will have less wrinkles and less freckles and beauty marks.

Answer 3

The cells on the outside (epidermis) are called keratinocytes (provide physical barrier) and melanocytes (provide colour and sun protection). These are both epithelial cells. The cells on the inside (dermis) are mainly dermal fibroblasts (also called mesenchyme), but there are a dozen or so others such as endothelial cells (blood vessels), smooth muscle cells (arterioles), Langerhans cells (defense/immune cells), sweat glands (epithelial cells), sebaceous glands (epithelial cells), Merkel cells (touch receptors), mast cells (defense/immune cells), lymphocytes (defense/immune cells) and neurons (nerve cells). Several other types of receptors such as stretch, temperature and pressure sensors, elements of the nervous system, are also present in skin.
