What are cell fragments in blood?

Platelets, also called thrombocytes, are cell fragments involved in blood clotting.

What causes fragmented cells?

The most common causes of abnormal fragmentation were malignancy with cytotoxic chemotherapy and severe iron deficiency. In two subjects, an abnormal red blood cell fragmentation pattern was the clue to a spectrin mutant in subjects with an automated blood count previously evaluated as normal.

What are the fragments of cells called?

Platelets, also called thrombocytes, are membrane-bound cell fragments derived from the fragmentation of larger precursor cells called megakaryocytes, which are derived from stem cells in the bone marrow. Platelets are important for the blood clotting process, making them essential for wound healing.

Are red blood cells fragments of cells?

The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).

Are cell fragments a component of blood?

Blood is composed of formed elements—erythrocytes, leukocytes, and cell fragments called platelets—and a fluid extracellular matrix called plasma. More than 90 percent of plasma is water.

Do high platelets cause blood clots?

A high platelet count can cause blood clots to develop spontaneously. Normally, your blood begins to clot to prevent a massive loss of blood after an injury. In people with primary thrombocythemia, however, blood clots can form suddenly and for no apparent reason. Abnormal blood clotting can be dangerous.

What are blood plates?

(PLAYT-let) A tiny, disc-shaped piece of cell that is found in the blood and spleen. Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They help form blood clots to slow or stop bleeding and to help wounds heal.

What are the four parts of the blood?

Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.

What are spur cells?

Spur cells, or acanthocytes (from the Greek word acantha, “thorn”), are erythrocytes covered with spikelike projections that vary in width, length, and distribution (see image below). They are characterized by diminished deformability, which is responsible for their entrapment and destruction in the spleen.
