Aspergillus niger spores (reproductive cells). The fungus Aspergillus niger is a widely distributed saprophyte which grows on household dust, soil, and decaying vegetable matter, including stale food. A. niger is one of the most common causes of fungal ear infections and may result in the serious lung disease aspergillosis in people with compromised immune function or other lung diseases. A. niger is used for waste management and biotransformation in addition to other industrial uses, such as production of citric acid and extracellular enzymes.

Bone marrow, stem cells of human bone marrow stem cells. These cells are known as multipotential stem cells because they form the precursors to every type of blood cell. During blood cell development the multipotential stem cell develops by a process known as haemopoiesis into either red blood cells  or one of three types of white blood cell (granulocytes, lymphocytes or monocytes).
