Which functional change of the red blood cells is seen in sickle red blood cells?
Sickle cells have an abnormality in the oxygen-carrying protein hemoglobin. Functionally, sickle cells are more rigid than normal red-blood cells. This can result in them getting "stuck" in capillaries because they don't deform as well as normal red-blood cells to allow them to flow through the capillaries. The sickle cells also break down faster than normal red-blood cells - due to their decreased elasticity they are more prone to "break" when trying to deform to flow through the blood vessels and capliaries, leading to anemia.
Where can one find the latest news on blood stem cells?
There are many websites detailing current news regarding blood stem cell research. The Cord Blood Registry website has a section dedicated to the latest stem cell news. Science Daily and Medical News Today are also good sources of up-to-date news in this field.
Where are Red blood cells white blood cells and platelets are found?
All the three are found in the blood.
Does apple cider vinegar with mother contain apple stem cells that stimulate collagen regeneration?
No. Stem cells are rather fragile, and do not survive for long outside the plant. Any remaining stem cells would die during the fermenting process of vinegar.
What is the biggest disadvantage of using unipotent stem cells for medical treatments?
they can only be used to create specific types of cells
When is an autologous stem cell transplant needed?
An autologous stem cell transplant is usually needed when a disease has damaged or destroyed bone marrow. Some diseases include Hodgkin's lymphoma, leukemia, multiple myeloma, and asplatic anemia.
What was the first stem cell banking facility to open in the US?
Amniotic stem cell bank a facility that stores stem cell derived from amniotic fluid for future use. the first private amniotic stem cell bank in the US was opened by Biocell center in October 2009 in Medford, Massachusetts.
Do embryonic stem cells contain half the number of chromosomes found in a zygote?
No. Stem cells are diploid just like any other body cell.
Skin stem cells can only produce other skin cells. what does this indicate about skin cells?
they are unipotent
What kind(s) of cells develop from uni-potent stem cells?
All kinds - but only one family for each type of uni-potent stem cell.
Which is the biggest disadvantage of using adult stem for medical treatments?
They are not pluripotent.(APEX)
How do you find out what medical trials are going on in Los Angeles using stem cells?
You can contact the California Institure for Regenerative Medicine to see what medical trials are going on in Los Angeles using stem cells.
What type of cell are stem stem cell described as?
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.
What can embryonic stem cell that are pluripotent do?
Embryonic stem cells that are pluripotent can develop into any type of cell.
What is the mass of stem cells produced in first few days after fertilization called?
A morula (mulberry) is an early stage in the development of the embryo at which it consists of a solid spherical ball of apparently identical cells. The morula stage is when one of the earliest prenatal diagnostic test can be carried out, by removing a single cell (blastomere) and carrying out genetic diagnosis on its DNA. Each one could develop into a complete animal (or human) since they are genetic the same.
Does your liver produce red blood cells in case of adults?
In case of the fetus, liver produces red blood cells. Red blood cells are produced by flat bones in case of adults. Given a challenge to produce the extra red blood cells, the liver may start producing red blood cells in adults also, as a last resort.
