Stem Cells

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.

There are three types of stem cells commonly found in the body: embryonic stem cells, induced pluripotent stem cells, and adult stem cells. Each of these stem cell types has different properties and capabilities for differentiation and regeneration.

Fat cells can potentially be used in spinal cord injury treatment by promoting tissue regeneration and providing a source of stem cells for repair. These cells have the ability to differentiate into various cell types that can contribute to the healing process and support nerve regeneration in the damaged area. Additionally, fat cells can be harvested from a patient's own body, reducing the risk of rejection and facilitating personalized treatment.

Stem Cell research has influence in diverse medical fields mostly in relation with the partial or almost total regeneration of organs and tissues. There is an increasing interest in its use in the treatment of heart pathologies among other fields.

Stem cells are 'cells with no specialization', they can become almost any kind of cell, including a tumor. However, stem cell research is directed to the regeneration of cells in dysfunctional but constitutionally normal tissues and organs and therefore are not likely to form tumors.

It is very difficult to classify stem-cell research as wrong, as it is a subjective (and very controversial) topic. The best way to find out whether it is 'right' or 'wrong' would be to determine it for yourself. It may be easier to do so once you know more about stem-cell research, by doing objective research and forming your own opinion. Here is the link to the 'What is stem-cell research?' question also on the wikianswers website: http://wiki.answers.com/Q/What_is_the_difference_between_embryonic_stem_cells_and_adult_stem_cells&alreadyAsked=1&rtitle=Stem_cell_research

The choices are

-they were harmed by radiation therapy

-they died off because the cancerous cells deprived them of nutrients

-they died off due to natural causes

- they thrived with the cancerous cells

There is currently no cure for multiple sclerosis (MS), but treatments are available to help manage symptoms, slow disease progression, and improve quality of life. These treatments may include medications to reduce inflammation, physical therapy to improve strength and mobility, and lifestyle modifications such as stress management and a healthy diet. It's important for individuals with MS to work closely with healthcare providers to develop a personalized treatment plan.

Epidermis The structure and functions of this tissue are the same as those of the epidermis of the stem of a dicotyledonous plant. The epidermis consists of a single layer of living cells which are closely packed. The walls are thickenedand covered with a thin waterproof layer called the cuticle. Stomata with guard cells are found in the epidermis. In some stems either unicellular or multicellular hair-like outgrowths, trichomes, appear from the epidermis. * Functions * The epidermis protects the underlying tissues. * The cuticle prevents the desiccation of inner tissues and thus prevents water loss . * The stomata allows gaseous exchange for the processes of respiration and photosynthesis. Ground Tissue This region is composed of small, thick-walled sclerenchyma on the inside of the epidermis. These layers of cells are followed by larger thin-walled parenchyma cells. Intercellular air spaces are found in the parenchyma. A cortex or pith is absent. * Functions * Sclerenchyma tissue strengthensthe stem. * Parenchyma tissue stores synthesised organic food such as starch. * Intercellular air spaces allow the exchange of gases. Vascular Bundles The vascular bundles are found scattered throughout the ground tissue. The vascular bundles occurring nearer the rind of the stemare smaller and are closer to one another. The vascular bundles contain no cambium and consequently secondary thickening does not occur. The vascular bundle is composed of the following parts:* Sclerenchyma sheath Thick-walled sclerenchyma fibres surround the vascular bundle. ** Function of the Sclerenchyma sheath ** Sclerenchyma sheaths protect the vascularbundles and give strength to the stem. * Xylem Large xylem vessels are found within an irregular intercellular air space called the lysigenous cavity. This space is surrounded by thin-walled parenchyma cells. ** Functions of the Xylem ** Xylem transports water and dissolved ionsfrom the root system to the stem. ** The lignified thick-walled xylem cells strengthen the stem. * Phloem Phloem is composed of thin-walled cells, viz. sieve tubes and companion cells. ** Function of the Phloem ** The phloem transports synthesized organic food such as carbohydrates from the leaves to other parts of the plant

The research of undeveloped cells in aborted fetuses. These cells can be inserted into a diseased or abnormal part of a person's body and they can develop into whatever kind of cell they're surrounded by. This can repair and heal the affected area.

a stem cell line is a group of stem cells that has the ability to produce one specific type of cell. for example, one stem cell line could have the ability to produce a kidney, while another line could produce a liver.
