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:

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

Hematopoietic Stem Cells

Wikipedia

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

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