What can stem cells be used for GCSE biology?

Stem cells can be used to treat humans. Therapeutic cloning can be used to treat diabetes. Embryonic stem cells (that can specialise in any type of cell) are produced with the same genes as the person who needs the treatment, when these cells are put into the body they are not usually rejected.

What are the types of stem cells GCSE?

There are two types of stem cells:

adult stem cells – these can develop into many (but not all) types of cell.
embryonic stem cells – these can develop into any type of cell.

Where are stem cells found GCSE?

Stem cells in plants Cell division in plants occurs in regions called meristems . Cells of the meristem can differentiate to produce all types of plant cells at any time during the life of the plant. The main meristems are close to the tip of the shoot, and the tip of the root.

What is a stem cell GCSE Edexcel?

A stem cell is an undifferentiated cell of an organism that is capable of dividing to produce many more cells of the same type (undifferentiated stem cells) In addition, stem cells can also give rise to other cell types through the process of differentiation.

What can stem cells treat BBC Bitesize?

Stem cells can divide to produce new cells, which can then divide into different cell types. They therefore have the potential to be transplanted into patients to treat medical conditions and disease. They could be used to replace cells that have been damaged or destroyed, for example: in type 1 diabetes.

Why are stem cells cloned GCSE?

Therapeutic cloning could produce stem cells with the same genetic make-up as the patient. The technique involves the transfer of the nucleus from a cell of the patient, to an egg cell whose nucleus has been removed. Stem cells produced in this way could be transferred to the patient.

What is a stem GCSE?

The term STEM is an acronym that stands for science, technology, engineering, and mathematics. The modern, connected world is dependent on technology.

What are the uses of stem cells BBC Bitesize?

What is stem stem cell?

Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells. They are unspecialized, so they cannot do specific functions in the body.

What are the advantages of using stem cells GCSE?

Advantages

(Embryonic Stem Cells) easy to extract from embryo.
(Embryonic Stem Cells) produce any type of cell.
(All Stem Cells) replace faulty cell with healthy cell, so the person is well again.
(Adult Stem Cells) no embryo is destroyed so not an ethical issue.

How are stem cells cloned?

The cloning procedure works by combining a patient’s body cell with an unfertilized egg cell from a donor. The stem cells can be induced to differentiate into different types of cells as needed (heart, nerve, muscle, etc.). These cells are genetically identical to the patient’s own cells (that is, they are cloned).

How are specialised cells formed in stem cells?

Mitosis is a type of cell division which produces two identical diploid daughter cells. Cancerous tumours are either malignant or benign. Specialised cells are formed when stem cells differentiate. Stem cells can divide to produce new cells, which can then divide into different cell types.

When do stem cells divide to produce gametes?

Cell division and stem cells. Cells divide by mitosis for growth and repair. They divide by meiosis to produce gametes for sexual reproduction. Stem cells differentiate into specialised cells during the development of organisms.

How are stem cells used to treat disease?

Which is the best source of stem cells?

The best source is the five-day-old embryo. Adult stem cells will differentiate into a narrower range of cell types. Bone marrow transplants are an example of adult stem cell transplant. Bone marrow cells will differentiate into different types of blood cells.
