what is the difference between stem cells and bone marrow?
931582
Stem cells are primal cells that retain the ability to renew themselves through cell division and can differentiate into a wide range of specialized cell types\n\nBone marrow (or medulla ossea) is the soft tissue found in the hollow interior of bones. It is the place where most new blood cells are produced.

Cell division reproduces the same kind of cell.  Cell differentiation is, in embrionic development, the situation wherein cells split-off in different "directions" to become very different things (eg., skin, spleen,...etc.)\n     An editorial:  Stem cell research is investigating the ways that very basics cells (think "undecided") might be introduced and encouraged to grow into cells... organs... to correct some sort of desease or injury.  I think it's a good thing!

Erythrocytes are produced in the bone marrow in adults and they are produced in the liver in an embryo. The spleen filters out old RBCs.

the bone marrow is the place in the body where the blood cells are produced ( Red, White and Platelets).\nA bone marrow biopsy tells the MD what the ratio between healthy, malignant and non-producing cells are.\nIn elderly people sometimes you see that the healthy cells are pushed to the side by non-producing cells (f.e.fat) or an overgrows of other cells like white cells ( leukemia).\nyou can also tell if there is a case of malnutrition or a lack of iron or vitamin ( B12).\nI hope it is a simple as that, but it is a very common thing in elderly people.

The skeletal system supports the whole body, including the bones. In addition to holding things up, and being propelled by the muscular system, Bones create blood in the marrow.

practicaly anithing!! Stem cells can replicate themselves or make any type of cell required to build an organism.

Blood is created in the bone marrow, or rather the red blood cells are created by hematopoetic stem cells.  however, there are MANY different kinds of cells in your blood, and getting them "matured" happens in many different places throughout your body, including the spleen, lymph system, etc.

That's a slightly odd question as each of those example has more than one cell type within it. Blood has red blood cells and several types of white, bones have several sorts of cells involved with them... and so forth. There are also issues like the fact red blood cells don't divide. I'm going to assume they're talking about the cells that create the blood, but that might be wrong. It's a vaguely worded question... if you got it as a homework question, you might want to get some clarification on exactly which cells are being asked about.\n\nYou can make a few generalisations. The two obvious ones for fast division are skin and blood, simply because they are both replaced regularly in the body. Bone cells aren't replaced so frequently as bones are more static, so would be have slower cell division.\n\nThe fast cell division answer for the plant cells is probably the root tip, as this does divide quickly. Plants do need to get their root system sorted out first, as otherwise they don't have a source of water/nutients to grow the rest.

No. All the types of blood cells differentiate from primary stem cells that are pluripotential (that is, they are capable of becoming any of the mature types). But once these cells differentiate into white and red blood cells, they have a limited existence, they serve their functions and die.

What exactly do u mean by phenotype?  I can tell you that bone marrow stem cells are the progenitors for osteoclasts, osteoblasts, and erythrocytes.

My husband was diagnosed with Non-Hodgkin's Lymphoma and was given an autologus stem cell transplant that sent him into remission from cancer.\n\nStem cells are master cells in your body that can form into other needed cells in your body, like muscle cells, blood cells, or brain cells.  Or, they can form more stem cells.  You can think of them like a constant repair system for your body.  \n\nIn the case of my husband, the cancer had invaded his bone marrow - this proved to be very serious since the marrow is where blood is made.  His own stem cells were harvested from his blood stream and sterilized to prevent any cancer from being saved.  An extremely high dose of chemotherapy was given to kill basically everything in his marrow.  The stem cells were then reintroduced to his body - and they went to work!  Since it's the stem cell's job to figure out what's needed to make the body function properly, it made new marrow cells!  And then he had new marrow and no cancer!\n\nThis is sort of a simplistic view, but I hope it helps!

There is debate about whether neural stem cells, or other types of adult stem cells exist. When talking about adult stem cells, it's important to define what a stem cell is. Cells can be totipotent, pluripotent, or multipotent.\n\nCells that are totipotent are capable of growing into a complete organism and can contribute to all tissues, including placenta. Cells that are pluripotent can contribute to all tissues, but cannot form placenta, and thus cannot form a complete organism. Cells that are multipotent can become more than one type of cell, but are already committed to a certain type of fate. An example would be a bone marrow stem cell that can become any of the types of blood cells, but can't become anything else.\n\nSome research has suggested that some multipotent cells can reverse their fate restrictions and become more types of cells. This is still very controversial and it may or may not actually happen. Something to keep in mind is that this is similar to what cancer cells do. Adult stem cells may have some strong similarities to cancer forming cells.\n\nEmbryonic stem cells remain the most viable scientific choice for therapeutics.

Long bones in adults don't produce blood cells (except for the parts closest to your shoulders and your pelvis).  Their marrow is filled with fatty tissue. (My theory is that long bones aren't used for blood cell production so that our evolutionary ancestors could lose an arm or a leg without jeprodizing their abiltiy to make blood cells)\n\nIn children, however, all bone marrow is devoted to the production of blood cells until the age of 5 or 6.

Yes, the donor marrow continues to produce cells with the donor's DNA, while the rest of the cells in the recipient contain the recipient's DNA. This happens for the rest of the recipient's life. The bone marrow contains stem cells that differentiate into blood cells and immune cells. Therefore the recipient will have cells that contain the DNA genome from either the donor or the recipient. However, only certain types of cells will have the donor DNA (blood and immune cells) and each cell will have only 1 type of DNA. The children of a bone marrow recipient will only get the recipient's DNA.
