Nope, they can differentiate into Neutrophils (White Blood Cells)
No. Some cells do not in fact have DNA, probably because of the lack of a nucleus. For example, mature red blood cells (erythrocytes) do not contain a nucleus or DNA.
No, mature human erythrocytes have no nucleus.
Virtually all eukaryotic (meaning all plants, animals, funghi, etc) cells have nuclei. The only exception of which I can think are erythrocytes (red blood cells) which lose their nuclei as they mature in mammals.
Erythrocytes or red blood cells are formed in the bone marrow from precursor cells called erythroblasts which themselves are formed from pleuripotential stem cells - the mother of all blood cells. Along the way, erythroblasts take various forms/ stages until they differentiate into mature erythrocytes.
They were at one point, but as they grow they differentiate and can no longer be counted as stem cells.
some members of the order Artiodactyla such as camel
Almost every cell (living or dead) contains DNA. There are a few very rare exceptions, including mature mammalian red blood cells (erythrocytes), which lose their contents to maximise oxygen carrying capacity. Young erythrocyte precursor cells, that will later become mature red blood cells, will contain DNA, as do red blood cells of other organisms (other than mammals).
stem cells
The formed elements of blood are related in that they are all the cells or cell fragments that comprise the solid portion of blood, and they arise from the same type of stem cell. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Technically yes they are because hemocytoblast stem cells create Myeloid stem cells and Lymphoid stem cells which produce all of the formed elements (white and red blood cells).
Hematopoietic stem cells are the parent cells for all formed elements of blood, including red blood cells, white blood cells, and platelets. These stem cells have the ability to differentiate into various specialized blood cells through a process called hematopoiesis.
Hematopoietic stem cells are the ancestors of all blood cells. These cells have the ability to differentiate into various types of blood cells, such as red blood cells, white blood cells, and platelets.
