Question 1

umbilical cord stem cell collection is available everywhere now?

Accepted Answer

Less used that fat: 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.

Question 2

after relapsing with nhl (diffuse large b-cell) is it better to do auto stem cell transplant or the collection only and then rituxan (rituximab) maintenance?

Accepted Answer

Depends: After a relapse, diffuse large b-cell lymphoma is only rarely cured using "conventional" chemotherapy. High-dose chemotherapy with autologous peripheral blood stem cell rescue is the best chance for long term survival and cure of this disease.

Question 3

what is a stem cell definition?

Accepted Answer

A starter cell: A stem cell is a cell that produces more specialized cells.  If you imagine all of the possible finished cells as leaves on a tree, with in between cells as the branches, the stem would be the trunk.

Question 4

tell me about stem cells please.?

Accepted Answer

Stem: Two types, embryonic which cells can develop into any tissue or organ; adult - cells which are within tissues to help maintain themselves or regenerate/repair damage tissues.  Adult cells are derived from fat tissue (by liposuction) and from bone marrow.  Exciting use in tendon/ligament, muscle, joint, chronic wounds, radiation damage, etc. Are currently being used with platelet conc to heal tissu.

Question 5

can you donate your own stem cells?

Accepted Answer

Yes: Harvesting of fat stem-stromal cells & bone marrow is possible. Some are storing these (cryopres) for future applicaitons.  Lipoaspiration provides the most numbers of mscs, and is currently used in many clinical applications in plastic surgery, wounds, and musculoskeletal disorders.

Question 6

facts, pros and cons of stem cell research?

Accepted Answer

Too big: That's a very large topic that can't even begin to be discussed in this small forum.  There are many volumes and centers that research this.  You might try some of these such as the university of pennsylvania center for bioethics.

Question 7

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

Accepted Answer

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.

Question 8

what is stem cell used for now that research is ok?

Accepted Answer

Current stemcell use: If i understand your question correctly, as to the current use of stem cells, clinically they are primarily used in aesthetic procedures like stem cell augmented fat transfers, and also in treating orthopedic conditions, such non-union of bone and arthritis.

Question 9

what is the definition or description of: stem cell?

Accepted Answer

A stem cell has: 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 cells for a lifetime.

Question 10

how are stem cells different from other types of cells?

Accepted Answer

Can become different: Stem cells have the potential to develop into a variety of cells found in our body. Most now use adult stem cells (usually from fat these days), these can become bone, cartilage, muscle, nerve, ligaments-tendons, etc in tissue culture. These cells are found throughout the body, wherever there are small blood vessels (microcapillaries) where most of these are stored, waiting to be called help heal.
