What does red bone marrow produce?
Red bone marrow has stem cells that grow into red blood cells, white blood cells, and platelets.
Is bone marrow an organ?

Can woman be impregnated by bone marrow?
By immersing stem cells harvested from men’s bone marrow in a cocktail of chemicals that mimic the environment of the testes, Nayernia and his team turned the stem cells into immature sperm. … Weirder still, a woman could conceivably use sperm made from her bone marrow to inseminate her own eggs.
Can humans green blood?
In sulfhemoglobin, the sulphur atom prevents the iron from binding to oxygen, and since it’s the oxygen-iron bonds that make our blood appear red, with sulfhemoglobin blood appears dark blue, green or black. Patients with sulfhemoglobinemia exhibit cyanosis, or a blueish tinge to their skin.
