Stem Cells

Embryonic stem cells have the ability to differentiate into any cell type, including those that make up intervertebral discs. However, due to ethical concerns and potential risks, research on using embryonic stem cells is limited. Adult stem cells, like mesenchymal stem cells, show promise in regenerative therapies for degenerative disc disorder by promoting tissue repair and regeneration. Clinical trials are ongoing to explore the potential of adult stem cells in treating this condition.

Yes, plants do have stem cells called meristematic cells. These cells are found in areas of growth, such as the tips of roots and shoots, and are responsible for generating new tissues throughout the plant's life.

There are adult stem cells and there are embryonic stem cells. Adult stem cells are found in many body tissues such as in the brain, neural stem cells, and in bone marrow. Also the embryonic stem cells, as you can tell by the name, are from the embryo which starts to develop into more recognizable specialized stem cells within three to four weeks after fertilization.

Stem cells are capable of self-renewal and assymetrical division to give rise to progenitor cells. Progenitor cells are cells that can further differentiate into other cells though it has lost the stem cell's ability to self-renew. When a stem cell divides, the same stem cell and a progenitor cell is produced. The production of the same stem cell is evidence of self-renewal and the production of a cell different from the parent cell is evidence of assymetrical division (regular mitosis gives rise to two identical daughter cells).

Adult stem cells can be isolated from a patient, typically from bone marrow or adipose tissue. These cells are then grown and differentiated into the specific cell type needed to treat the disease. The differentiated cells are then reintroduced into the patient to repair damaged tissues or organs, offering a potential treatment for diseases like heart disease or autoimmune disorders.

Yes. In fact, an umbilical cord blood can either be donated in public cord bank or preserved in a private cord bank. Many neurologists confirmed when a patient, diagnosed with a fatal disease (diabetes, leukemia, brain cancer, etc.), undergone cord blood transplant, he or she can be cured after a year or two. Successful stories about cord blood can be read in the attached blog.

Stem cells have the unique ability to self-renew and differentiate into different cell types because they are undifferentiated and have the potential to become specialized cells. Cheek cells, on the other hand, are already differentiated cells that have already reached their specialized state and do not have the capacity for self-renewal or differentiation.

Stem cells can be used in regenerative medicine to repair damaged tissues and organs, such as in treating spinal cord injuries by promoting nerve cell regeneration. They also hold potential in drug testing and development, as they can be grown into specific cell types for research purposes.

There are two kinds of stem cells: Embryonic and adult.

1. Embryonic stem cells are found in embryos.

An embryo develops from a fertilized egg, or zygote, and after about 4-5 days it reaches the stage where 50-150 cells are colonized. This means that one fertilized egg divides into 50-150 cells, which are considered embryonic stem cells. Also, they are totipotent, meaning that they can reproduce indefinitely, and can give rise to any type of cell.

2. Adult stem cells, or somatic stem cells, can be found in adult tissues throughout the human body. As adult stem cells are tissue specific, they are in the already developed tissues.

Some examples of where you can find stem cells in the human body:

Bone marrow= hematopoietic (blood) stem cells which differentiate into blood cells

endothelial stem cells = diff. into blood vessels (arteries, veins)

mesenchymal stem cells = diff. into bone, cartilage, muscle, fat, fibres

Cord blood= blood stem cells (similarly to bone marrow)

(Because of this similarity they might be considered as an alternative for bone marrow

transplant.)

fat = adipose stem cells, also similar to bone marrow, as they can

differentiate into bone, cartilage, fat, and muscle.

Stem cells exist also in human skin, mammary glands, placenta, lungs, and the brain (in which neural stem cells may or may not exist; it is up for debate).

The main function of adult stem cells is to replace damaged, or dying cells. They are pluripotent. Therefore, they too can reproduce indefinitely. However, while embryonic stem cells are able to develop into any kind of cell, adult stem cells are more limited.

Umbilical cord blood considered to contain "adult" stem cells, since they are not part of the embryo anymore.

The use of embryonic stem cells for research purposes is a highly debated question. However, research done on using adult stem cells is more widely accepted. Adult stem cells, found in bone marrow and in umbilical cord blood, are used routinely today.

Fortunately, pluripotent (adult stem cells) can be "reprogrammed", and, as a result, they could be regarded as equivalent to embryonic stem cells.

Just for an interest: deciduous baby teeth (milk teeth, which babies shed) can also be used as a source for adult stem cells.

Stem cells, with the ability to develop into different cell types, can be found not only in humans, but also in plants and animals.

Stem cells are the undifferentiated cells that have the ability to renew themselves for several generations. These cells are located on the matured or maturing organ systems of the adult or children. Found in Large Number of tissues, including epithelial layers of our skin. Umbilbical cord Embryo

No cheek cells are Heterotrophs.

Heterotrophs cannot make their own food.

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

A human cheek cell is a good example of a typical animal cell.

There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.

Adult stem cells can be harvested from various tissues in the body, such as bone marrow, adipose tissue, or blood. The process typically involves isolating the stem cells from the tissue through a minimally invasive procedure, such as bone marrow aspiration or apheresis. These harvested stem cells can then be used for various medical treatments or therapies.

stem cell research is performed on embryo's because the stem cells within them can duplicate into almost anything in the body, which benefits terminally ill people who have a bodily defect or if something in someone's body needs to be repaired

as long as the embryo is healthy the stem cells can be used to do this

however there is still alot of controversy surrounding this because some people (and on some level i agree) believe that embro's are still humans and therefore should be protected under the human rights legislation, and thereforeshould not be experimented on

hope this helped!!

Red blood cells and white blood cells are produced in your red bone marrow. Albumin is produced in your liver. Globulin is produced in your reticuloendothelial system. Water and the electrolyte are taken from the intestine.

Stem cells can be harvested from various tissues in the body, such as bone marrow, adipose tissue, and umbilical cord blood. However, not all tissues contain the same amount or quality of stem cells, and the method of collection may vary depending on the tissue source.

Stem cells do not necessarily grow faster than cancer cells. Cancer cells can divide more rapidly and uncontrollably than stem cells, which can contribute to the aggressive nature of cancer growth. However, stem cells have the ability to divide and differentiate into various cell types, while cancer cells typically lose this ability.

You could get bovine stem cells from a cow. These could be useful if you are trying to study stem cells themselves, however most stem cell research is for the purpose of human medicine. For medical applications bovine stem cells would not be of much use as they are significantly different from human stem cells.

Stem cells differ from regular cells majorly. One of the most common known facts about them is that they can regenarate any part of your body quickly. It is also related to cancer cells because they both are considered infinite. If anyone has anymore questions feel free to contact me at Over-lord-of-wow@hotmail.com. I will be more then happy to try and answer your answers and give you a couple of good sites that would be helpful to you. from antdog1234

The theory behind using stem-cells in SCI treatment, is that they can be used to regenerate glia (a type of cell in the spinal cord that is damaged badly during injury). In order for that treatment to be effective, however, it is believed that swelling of the cord must be controlled to prevent the formation of extremely tough and fiberous scar tissue. You can put as many new cells in there as you want, but it won't do any good if their growth is blocked by scar tissue.

Current experimental "treatments" involving stem cells in SCI survivors have shown to be ineffective.

Stem cells responsible for the production of white blood cells originate in the bone marrow. These stem cells differentiate, or specialize, into various types of white blood cells including lymphocytes, neutrophils, and monocytes.

A germ cell is a haploid cell (having only 23 chromosomes), such as a sperm or an egg. An embryonic stem cell is a diploid cell (containing 46 chromosomes) and is found in the inner cell mass of an embryo. This type of cell is pluripotent, meaning it can form any cell or tissue type.

A stem cell is a cell that has the ability to generate itself into any body part or cell type of the organism it is developing. Stem cells are found in the blastocyst of an embryo and ALSO in adults. Because adults have already finished developing, the stems cells are then used to maintain regenerative organs such as skin, blood or intestinal tissues. All other adult cells do not have the ability to regenerate.

Functions of the stem include:

1. Providing protection for the upper portions of the plant (those which normally carry the reproductive organs).

2. Protects the vascular system of the plant from environmental (weather), mechanical, insect or animal damage. In part the vascular system provides the stem with rigidity.

3. Contributes to the increase in surface area for photosynthesis, branches hold the leaves further away from the stem (where light levels can be lower), exposing more leaf area to the sun.

4. Stems also elevate the leaf canopy away from other plants which may be competing for the same sunlight (such as in dense jungles).

5. Transports water and minerals from roots to the leaves and prepared food to the roots and other plant parts.

The stem gives support and structure for the plant. The stem houses the xylem and phloem which transports water and nutrients from the root to other parts of the plant. It also protects from the leaves.

The stem on a plant works as the motorway of the plant. It transfers the nutrients collected by the roots to the actual flower and also anchors it into the ground.
