What type of cell can specialized cells give rise to?

Upvote6 Downvote1

This ability to become any type of cell in the body is called pluripotent. The difference between totipotent and pluripotent cells is only that totipotent cells can give rise to both the placenta and the embryo. 4. As the embryo grows these pluripotent cells develop into specialized, multipotent stem cells.

Subsequently, one may also ask, what is the difference between stem cells and specialized cells?

Stem cells differ from other kinds of cells in the body. 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.

What is specialization of cells?

Cell specialization, also known as cell differentiation, is the process by which generic cells change into specific cells meant to do certain tasks within the body. In adults, stem cells are specialized to replace cells that are worn out in the bone marrow, brain, heart and blood.

1

How does a stem cell become a specialized cell?

Stem cells can give rise to specialized cells. When unspecialized stem cells give rise to specialized cells, the process is called differentiation. While differentiating, the cell usually goes through several stages, becoming more specialized at each step.

2

How do cells become specialized?

Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

3

How do cells form a tissue?

Transcript of Cells form tissues, tissues form organs, organs form systems. Cells form tissues, tissues form organs, organs form systems and systems form organisms Tissues are made up of similar cells that carry out a common function. For example, muscle tissue is made up of many muscle cells grouped.

4

What is meant by specialized cells?

Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.

5

What are the factors that affect cell differentiation?

Environmental factors can also influence gene expression and cell differentiation. For example, available nutrients, salinity, and temperature are all factors that can influence gene expression in organisms. In Himalayan rabbits, genes that code for fur color are turned on and off depending on temperature.

6

What does it mean when a cell is undifferentiated?

Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly, stem cells come from two main sources: Embryos formed during the blastocyst phase of embryological development (embryonic stem cells) and. Adult tissue (adult stem cells).

7

How stem cells are differentiated?

In order to use stem cells to treat disease or as research tools to study disease, scientists must be able to differentiate stem cells into fully functioning specialized cells. Differentiation is the process where an unspecialized cell acquires cellular traits that allow it to perform specialized functions.

8

What is a niche of a stem cell?

Definition. A stem-cell niche is an area of a tissue that provides a specific microenvironment, in which stem cells are present in an undifferentiated and self-renewable state. Cells of the stem-cell niche interact with the stem cells to maintain them or promote their differentiation.

9

What Does stem cell therapy mean?

Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition. Bone marrow transplant is the most widely used stem-cell therapy, but some therapies derived from umbilical cord blood are also in use.

10

What is cell differentiation and why is it important?

Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression occurs because of certain signals in your body, both inside and outside of your cells. Cell differentiation occurs during multiple stages of development.

11

How are plant and animal cells specialized?

Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Note that cells may be specialised to carry out a particular function.

12

What is the need for cell Specialisation?

Cell specialisation. A zygote is a structure that forms when a sperm fertilises an egg. They are called embryonic stem cells. It is possible for embryonic stem cells to develop into any other specialised type of cell that the growing embryo needs - for example, nerve cells, blood cells and muscle cells.

13

How do cell division and cell differentiation work together?

Cell Differentiation and Tissue. Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of cells it contains.

14

What do you call a group of organs working together to perform a specific function?

A group of organs that work together to perform vital body functions is called a(n) ___. A specialized center of body function composed of several different types of tissues is called a(n) ___. An integrated group of cells with a common function, structure, or both is called a(n) ___.

15

What does it mean for a cell to differentiate?

cellular differentiation. The process by which a cell becomes specialized in order to perform a specific function, as in the case of a liver cell, a blood cell, or a neuron. There are more than 250 general types of cells in the human body.

16

What types of cells would most like not have cells undergoing division?

While WBCs do retain their nucleus while in peripheral circulation, most are also what we call terminally differentiated, since they can no longer undergo mitosis. Skeletal muscle can undergo hypertrophy, as each cell gets bigger. But skeletal muscle cells do undergo hyperplasia, since no new cells are generated.

17

What are the potential uses of stem cells?

Stem cells, directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat diseases including macular degeneration, spinal cord injury, stroke, burns, heart disease, diabetes, osteoarthritis, and rheumatoid arthritis.

18

What are undifferentiated cells?

Undifferentiated cells refers to a cell that has yet to develop into a particular cell variant. Undifferentiated stem cells are the very basic cells in biology that all other cells derive from. The very first few cells in an embryo are considered undifferentiated.(

19

What is the cell differentiation?

Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Differentiation occurs many times during the development of a multicellular organism. The organism changes from a single zygote to a complex system of tissues and cell types.

20

What is a stem cell line?

A stem cell line is a group of stem cells that is cultured in vitro and can be propagated indefinitely. Stem cell lines are derived from either animal or human tissues and come from one of three sources: embryonic stem cells, adult stem cells, or induced stem cells.
