These daughter cells eitherbecome new stem cells (self-renewal)or becomespecialized cells (differentiation)with a more specific function, such as blood cells, brain cells, heart muscle cells orbone cells. No other cell in the body has the natural ability to generate new cell types. Why is the...
What are the potential problems with using embryonic stem cells in humans?For embryonic stem cells to be useful, researchers must be certain that the stem cells will differentiate into the specific cell types desired.Researchers have discovered ways to direct stem cells to become specific types of...

you should put something back — he with his Newman s Own food and his Hole in the Wall camps for kids who are seriously ill, and me with Sundance and the institute and the festival. Paul and I didn t see each other all that regularly, but sharing that brought us together...
Problems with stem cells, replication and maturation of erythrocytes, the manufacture of hemoglobin, improper signaling between the kidney and bone marrow (erythropoietin), and problems with spleen function (destruction of cells by macrophages) can result in anemia. A person can have anemia because ...
Cells from, say, a patient with ALS can be collected, and (through a complex process) developed into pluripotent stem cells. Those cells can recreate, in the petri dish, the same motor neurons that cause such problems for the ALS patient. Research and drug develop...
Over the past decade, cancer stem cells have emerged as the centerpiece of cancer research, having a major role in resistance to conventional therapy and in the metastatic spread of tumours. The authors discuss the biological complexity of this subpopula
●Be careful with public charging stations and Wi-Fi. Charging stations and Wi-Fi are a convenience provided to the public, but they can bring risks for they may be connected to another compromised (缺乏免疫力的) device. If you connect to Wi-Fi and then it asks you to download something...
What was the problem with Gould’s research result according to Rakic() A. It was glue that Gould found. B. The new nerve cells exist in other parts of brains. C. The work has technical problems. D. Gould mistook the old cells as the new ones. ...
Different kinds of stem cells have variable risk profiles, but if someone tells you that the stem cell treatment they are selling has no risks then that is a big red flag and I would walk away. They are either woefully lacking in knowledge or aren’t being honest with you. Sometimes ...
