Topic 1:CellsHow are white blood cells created?You may ask.
Their origin is just like any other cell,be it the nerve cell,
muscle tissue cell or any of the other millions.
The stem cell of the blood marrow.
They do not serve any purpose as organs, but they can actually make
special cells to repair a part of the body, etc.
Thus, many scientists believe they can be very useful in medical
treatments and many nations are establishing funding in stem cell.
research to explore the possibilities of their development.
