Compare and contrast the effects of removing growth factors from asynchronous cultures of human cells that are normal and those that are cancerous.

Hi everyone. Let's look at the next problem. It says hematopoietic growth factors are essential in stimulating bone marrow to produce blood cells. What can happen if such gross factors are removed from the human system? So again, keywords here, they're essential necessary for the bone marrow to produce blood cells. So what happens if we remove these? Well, if you can't stimulate bone marrow to produce blood cells, you inhibit the production of blood cells. So let's look at our answer choices and see what reflects that choice. A says there will be a shortage of blood cells and that is correct. Without that essential stimulating factor we inhibit their production and therefore there won't be enough blood cells. So let's just look through to be thorough or other answer choices. Choice B says there have been over production of blood cells. Well, that's obviously incorrect as we're missing the essential growth factor to produce them. Choice C says there will be insufficient oxygen in the red blood cells. Well, it doesn't have an effect on blood cells carrying oxygen. It's just the production of blood cells themselves. Such choice C. Not the correct answer. And finally, Choice D. Says it will cause the blood cells to change their shape. Again, no effect on the blood cells once they're produced, it just affects the actual production of them. So Choice D. Not a correct answer. So again, if these growth factors essential to stimulating bone marrow to produce blood cells are removed from the human system. Choice A there will be a shortage of blood cells.
