Sideroblast (Sideroblasf)

Sideroblast cells

Sideroblasts are the precursors of red blood cells that contain iron-containing granules. They are present in healthy people, but may be absent in those who are deficient in iron.

One type of anemia is sideroblastic, in which abnormal ring-shaped sideroblasts are found in the blood. These cells are irregular in shape and contain large amounts of iron, which causes them to appear red.

With sideroblastic anemia, a decrease in the number of red blood cells and hemoglobin is observed in the blood, which can lead to oxygen starvation of tissues and organs. Treatment for this disease involves taking iron supplements and B vitamins.

Sideroblasts are precursors of red blood cells containing iron granules (iron oxides). They are more common in adults. Their functions have not been studied. They are used in medicine, veterinary medicine, cosmetology and in the production of dyes.

Content:

Sideroblasts (or siderocytes) are blood cells that contain hemes - parts of hemoglobin. Therefore, they have a characteristic blue-violet color and are clearly visible in the process of staining a peripheral blood smear. In fact, this is why sideroblasts were first considered as symptoms of diseases (anemia, pathologies of internal organs).

Hemes can also be present in the hemicapsid of bacteria, insects, fish, mollusks, and worms. They also include free heme dissolved in water or aqueous solutions of electrolytes, since it is able to penetrate into living cells and be oxidized there to form heme.

Humans and other mammals could not evolutionarily develop adaptations and become omnivores until single-celled eukaryotic organisms began to appear in various habitats, capable of synthesizing pigments and using soluble forms (siderophores) of hemes, which
