The common lymphoid progenitor matures into four mature categories of lymphocytes:

- B lymphocytes
- natural killer (NK) cells
- NK-T cells
- T lymphocytes

Common Lymphoid Progenitors

Myeloid stem cells, also called myeloid progenitors, mature into colony form unit (CFU) cells that produce their respective mature cell, including:

- neutrophils
- monocytes
- eosinophils
- basophils
- mast cells
- megakaryocytes
- erythrocytes

Myeloid Stem Cells

CD markers stand for clusters of differentiation, these are specific antigens on cells that help to identify the cells. Most common CD markers on lymphoid and myeloid stem cells are given below:

Hematopoiesis Figure

Three major types of formed elements include:

- red blood cells/erythrocytes
- platelets/thrombocytes
- white blood cells/leukocytes

Major Types of Formed Elements

These stem cells are pluripotent, meaning they can give rise to many different types of other cells and formed elements.  Hematopoietic stem cells are found in bone marrow and notably produce:

- lymphoid progenitors 
- myeloid stem cells

OpenStax Biology 2nd Edition

https://openstax.org/details/books/microbiology/

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
