No. They are considered a tissue not an organ. Since these cells are similar and work together, they fill the definition of a tissue. Tissues that work together are called organs.
Multipotent hematopoietic stem cells------> Myeloid stem cells------>Reticulocytes----->RBCs
Multipotent hematopoietic stem cells
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
The ancestors of all the blood cells are called hematopoietic (blood forming) stem cells.
Stem cells has the capability to regenerate and develop into any kind of tissue or organ, when supported with the external nutrients. So they are called as totipotent. There are two kinds of stem cell a)adult stem cells b)embryonic stem cells. There are various researches going on in this area .
Hematopoietic stem cells
Its a non hematopoietic stem cells which gives nourishment to hematopoietic stem cells(HSC)
There are two other sources of hematopoietic stem cells--bone marrow and peripheral blood

Multipotent hematopoietic stem cells
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
The blood cell begin their lives in the bone marrow from a single type of cell called pluripotent hematopoietic stem cell.All the circulating blood cells are eventually derived from PHSC.
