A stem cellis a cell v the unique capability to develop into specialised cell species in the body. Later on they might be provided toreplace cells and also tissues that have been damaged or lost because of disease.

You are watching: What property is unique to stem cells

What is a stem cell?

Stem cell provide new cells because that the body as itgrows, and also replace specialised cell that space damaged or lost. Theyhave two unique properties that allow them to carry out this: They have the right to divide over and over again to produce new cells. Together they divide, castle can adjust into theothertypes ofcellthat consist of the body.

Different types of stem cell

There space three main varieties of stem cell: embryonic stem cell adult stem cell induced pluripotent stem cells

Embryonic stem cells

these stem cells are said to it is in pluripotent, which means they can change into any cell in the body.

Adult stem cells

Adult stem cell supply new cells as an organism grows and to change cells that gain damaged. Adult stem cell are claimed to be multipotent, which method they can only change into part cells in the body, not any cell, for example: Blood (or "haematopoietic") stem cells can only replace the various varieties of cell in the blood. Skin (or "epithelial") stem cells administer the different species of cells that make up our skin and also hair.

Induced pluripotent stem cells

Induced pluripotent stem cells, or ‘iPS cells’, space stem cell that researchers make in the laboratory. ‘Induced’ method that they are made in the lab by taking common adult cells, prefer skin or blood cells, and reprogramming lock to come to be stem cells. As with embryonic stem cells, they are pluripotent so they can develop into any type of cell type.

Why are stem cell useful?

Stem cells have actually several provides including: research – to aid us know the straightforward biology that howliving points workand what wake up in different species of cell during disease. Therapy – come replace lost or damaged cells that our body can’t replace naturally.

Stem cell research

study is spring to better understand the properties of stem cell so that us can: understand just how our body grow and develop We have the right to use stem cell to study just how cells end up being specialised for specific functions in the body, and what happens once this process goes wrong in disease.

Stem cabinet therapy

Stem cells might be one way of generating new cells that deserve to then it is in transplanted right into the human body to change those that space damaged or lost. Adult stem cells are right now used come treat part conditions, because that example: Blood stem cells are provided to carry out a resource of healthy and balanced blood cells for world with some blood conditions, such as thalassaemia, and cancer patients who have lost their very own blood stem cells throughout treatment. Skin stem cells can be used to generate new skin for civilization with severe burns. Age-related macular degeneration (AMD) is an instance of a an illness where stem cells can be provided as a new kind of therapy in the future: researchers are using induced pluripotent stem cells to produce brand-new RPE cells in the laboratory that have the right to then be put right into a patient’s eye to replace the damaged cells.

Stem cells can be used to generate new organs for usage in transplants: Currently, damaged organs can be replaced by obtaining healthy organs native a donor, but donated organs may be "rejected" by the body together the immune device sees it together something that is foreign. Induced pluripotent stem cells produced from the patient themselves could be offered to grow brand-new organs that would have actually a lower risk of gift rejected.

How execute you generate induced pluripotent stem cells?

To generate induced pluripotent stem cells, researchers re-introduce the signals that generally tell stem cells to continue to be as stem cell in the beforehand embryo. This switch off any type of genes that tell the cell to it is in specialised, and also switch on genes that phone call the cabinet to it is in a stem cell.
