Stem Cell (Definition)

The capacity to "grow up" or differentiate to produce mature cellular elements. In blood production rbc, WBC and platelets. Fundamentally, stem cells can also self-replicate and thus provide a pool of ...Read more

In what ways are stem cells extracted from the human body?

In what ways are stem cells extracted from the human body?

Stem Cell Extraction: Up until now, the most common way to extract stem cells has been from bone marrow. However, the stem cell yield from bone marrow is low, and therefore these cells usually need to be culture expanded for therapeutic purposes. The good news is that adipose tissue has a very high concentration of stem cells. Look for future developments in this evolving field! ...Read more

What are human embryonic stem cells used for?

What are human embryonic stem cells used for?

A this poitnt: Human embryonic stem cells are being studied to define stem cell biology and in animal models to look at tissue and organ repair. This would be considered preclincial at this point, whcih is to say he's are not being used to treat human disease. ...Read more

What are doctors' opinions on human stem cell research?

Promising!: So far it is useful in treating disorders of the bone marrow. Other ways of treating diseases using stem cells are under investigation. ...Read more

Are stem cells specific to an individual or mammal? Ie, could you take stem cells from an animal and put them in a human and expect them to survive?

Are stem cells specific to an individual or mammal? Ie, could you take stem cells from an animal and put them in a human and expect them to survive?

Specific, tho doable: Ethical and regulatory issues aside, large animal stem cell sources including transgenic humanized pigs etc are in intense research for regenerative medicine tx for humans. Stem cells, though less immunogenic, may be genetically modified to have similar human HLA type, and could survive, with immunosuppression, in limited settings, . ..though I believe most are still experimental. ...Read more

What is the function of a stem cell in the body?

Progenitor cell: A stem cell is the starting point from which other cells grow out of. For example, stem cells can be given to a cancer patient who has undergone bone marrow ablation so that new bone marrow can grow in its place. ...Read more

I'm curious as to how hard is it to find stem cells in the body?

I'm curious as to how hard is it to find stem cells in the body?

Easy: Adult stem cells are found within all tissues with blood supply. Tiny micro-capillaries are primary locations. Most common means of harvestin comes via minimally invasive, using microcannulas (lipoaspirating) on small syringes to obtain the adipose cells (highest in non-blood type stem cells). These can become bone, cartilage, nerve, tendon-ligament, depending on where placed or located by signals. ...Read more

Where are most stem cells found in the body? Do adults have them?

Where are most stem cells found in the body? Do adults have them?

Bone marrow & Yes: All tissue have stem cells. Stem cells are easily retrieved from the bone marrow and peripheral blood. Adult do have stem cells.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

I'm wondering can the human body survive without a functioning brain stem?

I'm wondering can the human body survive without a functioning brain stem?

Likely not: The brain stem controls vegetative functions - respiration and awareness. Loss of the brain stem would result in coma and unable to breathe. ...Read more

Regrow teeth by stem cells when? From 2009 no updating. By stem cells Treated Several things on humans. Teeth? Tired from waiting. Expectation plz

Tired of waiting?: Why not replace the missing teeth today with dental implants? No need to wait. Although the research is promising, you may not see the technique used for missing teeth in the near future. ...Read more

I have no movement on the left part of the body due to brain stroke. Is it possible to cure it by stem cell therapy?

I have no movement on the left part of the body due to brain stroke. Is it possible to cure it by stem cell therapy?

Not at this time: There have been some research trials in stem cell therapy for paralysis from stroke but unfortunately no breakthroughs to my knowledge. The university of pittsburgh medical school has been out in front with this type of research. Hopefully someday there will be a treatment that can reverse paralysis. ...Read more

A relative of mine has lost movement of left part of the body due to brain stroke. Could stem cell therapy work for this?

Not yet: Stem cell research has loads of promise, but it is premature to anticipate clinical outcomes. We are still in the infancy stage, and unlikely to have breakthroughs for years, in spite of news reports. ...Read more

Stem cell apheresis for bone marrow transplant? How does this work and is it safe? I thought bone marrow stem cells were inside your bones, so how can you collect them from your blood? Also, can your body make more bone marrow without the stem cells?

Stem cell apheresis for bone marrow transplant? How does this work and is it safe? I thought bone marrow stem cells were inside your bones, so how can you collect them from your blood? Also, can your body make more bone marrow without the stem cells?

Most: Most bone marrow stem cells are inside you bones, some are floating around. When given a medication/natural substance called gcsf or Neupogen more stem cells are found in the peripheral blood. These can be removed by a machine that filters your blood. An IV is placed in two places, your blood is removed, filtered and returned. You are left with stem cells so you too continue to make blood. ...Read more

What is stem cell transplantation's status in the u.S. Now?

Used non-manipulated: Use of adult mesenchymal stem-stromal cells (mscs) are currently in clinical trial in us/internationally. Trend is toward use of fat derived mscs, havested by liposuction, isolated and concentrated in tissue culture. Early reports suggest significant improvement in neurological, autoimmune and organ functions. Many more mscs in fat than bone marrow making ad-msc the center of most research now. ...Read more

Stem cell therapy, is it approve in the u.S?

Stem cell therapy: It involves the use of stem or pluripotent cells that, under the proper triggers, can grow into many different cell types. Stem cells are transplanted to replace damaged cells or tissues in the body that are unable to heal themselves. While this type of therapy does offer hope, it is mostly investigational at this time and very few stem cell therapies have been proven to be both safe and effective. ...Read more
