Granulopoiesis
Encyclopedia
Granulopoiesis is hematopoiesis of granulocyte

It occurs primarily within bone marrow

Granulocyte
Granulocytes are a category of white blood cells characterized by the presence of granules in their cytoplasm. They are also called polymorphonuclear leukocytes because of the varying shapes of the nucleus, which is usually lobed into three segments...

Bone marrow
Bone marrow is the flexible tissue found in the interior of bones. In humans, bone marrow in large bones produces new blood cells. On average, bone marrow constitutes 4% of the total body mass of humans; in adults weighing 65 kg , bone marrow accounts for approximately 2.6 kg...

- Pluripotential hemopoietic stem cellPluripotential hemopoietic stem cellHematopoietic stem cells , also spelled Hæmatopoietic stem cells, are multipotent stem cells that give rise to all the blood cell types from the myeloid , and lymphoid lineages...
- MyeloblastMyeloblastThe myeloblast is a unipotent stem cell, which will differentiate into one of the actors of the Granulocyte series.- Origin :These cells descend from the primitive reticulum cells, which are found in the stroma of the marrow. There is also an intermediate phase between the myeloblast and these...
- PromyelocytePromyelocyteA promyelocyte is a granulocyte precursor, developing from the myeloblast and developing into the myelocyte.-External links: - "18. Bone Marrow and Hemopoiesis: bone marrow smear, promyelocyte and erythroblasts " "Bone marrow" "Bone marrow"* - "Bone marrow smear"...
- Eosino/neutro/basophilic myelocyte
- MetamyelocyteMetamyelocyteA metamyelocyte is a cell undergoing granulopoiesis, derived from a myelocyte, and leading to a band cell.It is characterized by the appearance of a bent nucleus, cytoplasmic granules, and the absence of visible nucleoli...
- Band cellBand cellA band cell is a cell undergoing granulopoiesis, derived from a metamyelocyte, and leading to a mature granulocyte.It is characterized by having a nucleus which is curved, but not lobar....

Candida albicans
Candida albicans is a diploid fungus that grows both as yeast and filamentous cells and a causal agent of opportunistic oral and genital infections in humans. Systemic fungal infections including those by C...
