Bone marrow aspiration and trephine biopsy are usually performed on the back of the hipbone, or posterior iliac crest. An aspirate can also be obtained from the sternum (breastbone). For the sternal aspirate, the patient lies on their back, with a pillow under the shoulder to raise the chest.
The most commonly used source of MSC's is bone marrow aspirate. Most of the adult bone marrow consists of blood cells in various stages of differentiation. [10] These marrow components can be divided into plasma, red blood cells, platelets, and nucleated cells. The adult stem cell fraction is present in the nucleated cells of the marrow.
The Jamshidi needle is a trephine needle for performing bone marrow biopsy, whereby a cylindrical sample of tissue, a core biopsy specimen, is obtained. It is a cylindrical needle with a tapered cutting tip. [1] The tapered end reduces the potential of crush artifact. [2] It is the most commonly used needle for performing bone marrow biopsies. [3]
In mesenchymal stem cell therapy, most of the cells are extracted from the adult patient's bone marrow [2] [3] Mesenchymal stem cells can be obtained via a procedure called bone marrow aspiration. A needle is inserted into the back of the patients hip bone and cells are removed to be grown under controlled in vitro conditions in a lab. Over a ...

A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
Romanowsky-type stains are widely used in the examination of blood, in the form of blood films, and in the microscopic examination of bone marrow biopsies and aspirate smears. [1] [23] Examination of both blood and bone marrow can be of importance in the diagnosis of a variety of blood diseases.
