Stem Cells
Stem cells are a biological cell that can turn into a specialized cell, and then divide to create more.
678 Questions
What is stem cells main function?
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. They have two unique properties that enable them to do this: They can divide over and over again to produce new cells. As they divide, they can change into the other types of cells that make up the body. Obviously, due to the characteristics and functions of stem cells, stem cell-based treatments have developed rapidly in the past ten years. Stem cell therapy has been successfully used to potentially treat more than 80 approved disorders.
Anyway, stem cells play an important role in the development of human medicine. The services of stem cell therapy provided by Creative Biolabs can help you better complete your research.
What is the use of stem cells an ethical concern?
There was ethical concern over stem cell research because of where they originally collected stem cell from. They first thought that only aborted babies had the stem cells we were looking for, but they're not used anymore.
How does baby blood differ from adult blood?
fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream.
How can human stem cells be used?
Human stem cells can be used in various ways such as regenerative medicine to repair damaged tissues and organs, in drug testing and development to study disease mechanisms and potential treatments, and in disease modeling to better understand genetic disorders and identify potential therapeutic targets. Stem cells can also be used in cell-based therapies for conditions such as spinal cord injury, heart disease, and diabetes.
Why is it that a stem cell has potential medical uses?
Stem cells have so much potential in research because they have the ability to develop into any type of cell. Your body is made up of many different types of cells: red blood cells, white blood cells, glial cells, neurons, and muscle cells, just to name a few. By manipulating stem cells, the possibility for many different things arises in science. Could we regenerate an arm? Grow a heart? Replace lost neurons, the cells responsible for sensation and motor movement? There are two types of stem cells: adult stem cells, which are found in the umbilical cord, placenta and most adult tissue and those made from newly developed fetuses, called embryonic stem cells. This is where the controversy lies. Where do you draw the line when using fetuses (killing life) for medical research (possibly prolonging the life of those who have already been living for a significant period of time)?
When was Cell Stem Cell created?
"Stem cell research has been around for almost as long as microscopes. Though it is only within the 1980s that more sophisticated genetechnology developments have allowed for the culturing (growing of cells) in laboratories. Fetal nerve cells were one of the first 'stem cells" not real stem cells though were used to treat Parkinson." source: Lasker Foundation
What would happen if we didn't have stem cells in our body?
well,if we had no cells...how will we live?
that's a composition of our body eversince..
and there's no such thing as living things with no cells,coz even our blood is composed of cells.
I can't imagine...but I think there is a specie with no cell.As of us humans,we really are in need of cells.And there's no any known incident yet with a human having no cell at all.
Hope this helped. ^^,
What type of stem is a softer and more flexible type?
well the hard stemm is woody so im guessin the other stem is the herbaceous stem
Why do stem cells have large nuclei?
Having spent the last week looking at papers relating to neurons, nuclei and nucleoli while trying to answer a related question, I think it would be fair to say that, at the moment, nobody knows.
I have a hunch as to what the answer might be, but I can't find anyone else with the same idea, so it is perhaps a little too soon to post the idea here
Why are stem cells used in medicine?
There are my benefits of stem cell trreatment and And the one who has benefited with me is this My cousin was diagnosed with Macular Degeneration two years ago. She was gradually losing her eyesight. After much consideration, we decided to try stem cell treatment. We called StemCellTherapyIndia in India and explained to them my cousin’s condition and they recommended that she undergo stem cell treatment. She underwent the process shortly after. After the procedure, her vision got significantly better. We are so glad we chose StemCellTherapyIndia. Highly recommended.
What type of disease might most likely be cured by stem cell transplantation?
In theory, any broken cell or damaged cell can be cured with the use of stem cells. Knew limbs can be created but they do not know a structure.
What is some current research on the benefits of stem cells?
Scientists have been doing tests with stem cells and they have found that with the cells it can be a cure on diabetes. They have tested it on rats and it has worked.
It can also help your lungs.
What can stem cells help to cure?
Nobody knows for certain, but it is possible that it might be used to treat or cure a variety of diseases where specific types of cells are missing (either because they were never there, they died out, an autoimmune disorder killed them off, etc.). A few of these possibilities are:
- Parkinson's - caused by the loss of dopamine producing cells in the substantia nigra in the brain
- Diabetes (type I) - caused by the death of insulin producing cells in the Islets of Langerhans in the pancreas
A disease resulting from abnormal proliferation of stem cells in bone marrow?
This cancer type is called myeloma.
Pluripotent cell can differentiate into almost any type of cell.
Where is a stem cell of an embryo are the instructions located for how to build the heart?
deoxyribonucleic acid
Why are embryonic stems cells especially useful in medical research?
If people research embryonic stem cells, we can further put them into use into medicine. Using the somatic cell nuclear transfer method, scientists can grow human organs and tissues and then implant them into a human being. Further research can shed light on new ways to circumvent the body rejecting the given tissue.
What cells are present in plant stems?
The function of the cell membrane is to allow waste material to exit the cell. The cell membrane forms a barrier between the inside of the cell and the outside, so that the chemical environments on both sides can be different. It regulates the movement of materials into and out of the cell.
Cell WallThe function of the cell wall is to provide structural support and to control the amount of water entering the cell. The cell wall is a wall that allows the circulation and distribution of water, minerals, and other small nutrient molecules into and out of the cell. It gives rigid support from which stable structures like leaves and stems can be produced. It can also sense the presence of pathogenic microbes and control the development of tissues within the cell because of its storage site of regulatory molecules Golgi BodyThe Golgi body stores, packages, and distributes the lipids and proteins made in the endoplasmic reticulum. It puts proteins into packages, called vesicles. Rough Endoplasmic ReticulumThe function of the rough endoplasmic reticulum is to synthesize and exports proteins and glycoproteins. LysosomesThe purpose of lysosomes are to digest things. They could be used to digest food or break down the cell when it dies. Lysosomes are The cell's garbage disposal system. They clean up while patrolling the cell. This organelle breaks down large molecules into many smaller molecules by using their special proteins. The smaller molecules can be used as building blocks for other large ones. Lysosomes also kill and digest invading organisms. CytoplasmThe function of the cytoplasm is to distribute oxygen and food (nutrients) to other parts of the cell and it supports all parts inside the cell. It has three main functions: storage, energy, and manufacturing. The cytoplasm contains nutrients that have been dissolved which help for the dissolving of waste products NucleolusThe nucleolus is where ribosomes are made. The nucleolus disappears during cell reproduction. This is because ribosomes are not needed when cells reproduce. VacuoleThe function of the vacuole is to store water, nutrients, and other substances that cannot be used right away. They tend to be larger in plant cells because plants are watered. When they are well watered, water collects in cell vacuoles producing rigidity in plants. Each plant cell has a large, single vacuole that stores compounds, helps in plant growth, and plays a significant structural role for the plant. RibosomesRibosomes are the protein builders or protein synthesizers of the cell.- #*
The amylosplast is an organelle in some plant cells that store starch.
Druse CrystalThe druse crystal, often found in plant vacuoles, is a granular type of crystal usually composed of calcium oxalate. The druse crystal is said to deter herbivory. Centrosome:The centrosome is an area in the cell where microtubules are produced. Microtubules carry out a variety of functions, ranging from transportation to structural support. During cell division, the centrosome divides, and both parts move to opposite sides of the cell. Raphide Crystal:The raphide crystal, usually composed of calcium oxalate, is a needle kind of crystal often found in plant vacuoles. It is thought to slow down herbivory. Golgi Vesicles:The Golgi vesicles carry the proteins and lipids to take them to other parts of the cell or to the outside of the cell.Hoped i helped
ADDITION-
The Stem-
It helps hold up the plant.But not only that,It can also carry the water and the minerals it got from the roots.The roots carry the water it absorbed from the ground,then the water goes up to the stem,then the water and minerals go to the leaves to make food for the plant.The process of the plant making food is called photosynthesis.
Why did doctors use embryonic stem cells?
Scientists use stem cells because they can generate healthy cells and replace disease ones. Plus they allow them to test and better understand disease and test new drugs for effectiveness.
Are adult stem cells totipotent cells?
What kind(s) of cells can develop from multipotent stem cells?
A. Only cells that are closely related to the original stem cell B. Only cells that are identical to the original stem cell C. Any cells of the human body or the placenta D. Any cells of the human body. but not cells of the placentaWhere have stem cells come from traditionally?
blastocysts (balls of unspecialised cells which become a baby)
What controls the way stem cells divide and differentiate?
Ultimately their genetics. However various genes get turned off at programmed times by methylation of the DNA while others get turned on at programmed times by demethylation of the DNA. The methylated/demethylated forms of the DNA are passed on to the stem cell's descendants so they "retain their programmed state" and thus their identity following differentiation. Some of this program control is influenced by the concentrations of various chemicals secreted by other cells in the vicinity of the stem cell or its descendants.
What part of a developing embryo are stem cells derived from?
Stem cells come from newly fertilized eggs.
What is a disadvantage of using a globe?
Hard to see 2 far away places at once.
