Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.

Additional, how do unspecialized cells become specialized?
Chapter Review Cell differentiation is the process of cells becoming specialized as they body develops. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Furthermore, what is it called when stem cells become Specialised? These cells are called embryonic stem cells and can become specialised to form any type of cell. They do this by switching genes on and off.
Still, are stem cells specialized or unspecialized?
Stem cells have unspecialized capability and do not have tissue- specific structures to perform specialized functions. They can give rise to specialized cells: Stem cells go through a process called differentiation and create special types of cells (muscle, nerve, skin, etc.).

People who might benefit from stem cell therapies include those with spinal cord injuries, type 1 diabetes, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer's disease, heart disease, stroke, burns, cancer and osteoarthritis.
They can transport molecules, metabolize nutrients, and reproduce within this one cell. Multicellular organisms need many different types of cells to carry out the same life processes. ... Cell differentiation is the process by which cells become specialized in order to perform different functions.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii.
An unspecialized cell that can divide and give rise to different specialized cells
is called a stem cell
(Figure above). Zygotes and embryonic cells are both types of stem cells
. These stem cells
, called embryonic stem cells
, can divide indefinitely and can specialize into any cell type. They are totipotent.
Types of Adult Stem Cells:
- Hematopoietic Stem Cells (Blood Stem Cells)
- Mesenchymal Stem Cells.
- Neural Stem Cells.
- Epithelial Stem Cells.
- Skin Stem Cells.
Precious Stem Cells From Birth: Umbilical Cord Blood They can be extracted immediately after birth, with no harm or risk to the mother or baby—making it not only a non-invasive and low cost source of stem cells, but an incredibly healthy source too, due to minimal damage from pollution and ageing.
According to the Mayo Clinic, stem cells can be used to:
- grow new cells in a laboratory to replace damaged organs or tissues.
- correct parts of organs that don't work properly.
- research causes of genetic defects in cells.
- research how diseases occur or why certain cells develop into cancer cells.
Stem cells are divided into 2 main forms. They are embryonic stem cells and adult stem cells. Embryonic stem cells. The embryonic stem cells used in research today come from unused embryos.
All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.
The stem cells may be obtained from sources such as:
- Bone marrow.
- Umbilical cord blood.
- Adipose tissue.
- Amniotic fluid.
For many patients, Stem Cell Therapy

Researchers hope stem cells will one day be effective in the treatment of many medical conditions and diseases. But unproven stem cell treatments can be unsafe—so get all of the facts if you're considering any treatment. Stem cells have been called everything from cure-alls to miracle treatments.
Share: Stem cell treatment for knee, back, shoulder, and joint pain can have varying results in terms of how long the pain relief lasts. Several studies using stem cells as a treatment for arthritis have shown lasting results anywhere from six months to several years.
