Why can you not just use stem cells from adult bone marrow in stem cell research?
Adult bone marrow stem cells have limitations compared to embryonic stem cells, such as a lower potential for differentiation into various cell types. Embryonic stem cells are considered more versatile and can give rise to a wider range of cell types, making them more suitable for research and potential therapeutic applications. Additionally, adult bone marrow stem cells may not be as pluripotent as other types of stem cells, which could affect their effectiveness in certain research and treatment contexts.
Are all bone marrow stem cells producing abnormal cells when someone has leukemia or just some of them?
In leukemia, a small proportion of bone marrow stem cells become malignant and start producing abnormal cells. These abnormal cells then grow uncontrollably, crowding out normal blood cells. The majority of bone marrow stem cells remain healthy and continue to produce normal blood cells.
What is the function of the yellow marrow bone?
Yellow bone marrow stores fat, which the body consumes as a last resort in cases of extreme starvation. It also turns into red marrow in emergencies such as blood loss or anemia. Miraculously, this process can happen in just a few hours. Red bone marrow produces all blood cells, except lymphocytes which are produced in the marrow and reach maturity in the generative lymphatic tissues, such as the thymus gland or bone marrow.
Which parts of the human body contain stem cells?
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.
What makes new blood cells and can be found in the middle of your body?
in your blood! yeah i know that i wanted to know where they were made because thats not in your blood but i know now cuz i asked that question about three years ago! btw they are made in the red bone marrow (the white is just fat)

Which bone cell is derived from the bone marrow?
Osteoclasts. They are phagocytic just like macrophages and originate from the same stem cells in the bone marrow as macrophages.
Is there a thing called white marrow?
No, there is not a thing called white marrow, just white blood cells and bone marrow.
What contains fat in adult bones?
Well, first, make sure that you know that there is both Fatty substance and bone marrow. The bone marrow makes Red blood cells, as well as many others. The fatty substances are for support, shock absorbtion, and just as a place to store excess energy, in the form of fat.
What is the function yellow bone marrow?

What are bone marrow made up of?
They are not made up of bone marrow, they just have bone marrow in them.

Red bone marrow is found in spongy or compact bone?
Bone marrow is the substance that is found at the core of bones, and is either made of fat or red blood cells depending on the type of bone in question. For spongy bone, the marrow is made of red blood cells.
What is the role of red bone marrow?
Bone marrow, a soft tissue dwelling in cavities in the middle of bones, can be divided into two categories: red marrow and yellow marrow. Yellow marrow is made up of blood vessels, nerve cells, and fat cells, while red marrow produces red blood cells as well as special white blood cells (lymphocytes), and other elements of the blood such as platelets.
How do red and yellow bone marrow differ in composition and function?
Red Bone Marrow produces both red and white bloode cell's. Yellow marrow, which is found in the central cavity of long bones, stores fat.Cross Section of a long bone below:In children red marrow dills the center of long bones this red marrow is replaced with yellow marrow as children become adults.
Do reptiles have bone marrow?
Yes, reptiles do have bone marrow. It is responsible for producing red and white blood cells in their bodies, just like in other vertebrates. However, the structure and function of bone marrow in reptiles may vary slightly compared to mammals.
What is a bone marrow be specific?
Bone marrow is spongy white and dose not just sit in our bones. People with cancer need bone marrow transplant because the bone marrow is needed for our immune system.
