The precursor of all lines of blood cells is the hemocytoblast.
hemocytoblast
Lymphoid and myeloid
Erythropoietin
Hemocytoblast.
Pleuripotent stem cell
hematopoietic stem cell (hemocytoblast)
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).
Mesenchymal Stem Cell and Marrow Stromal Cell, These have been used for this interchangeably for years.
It is a phase in the production of erythrocytes where hemoglobin and spectrin are beginning to be produced by the ribosomes of the hemocytoblast stem cells in red bone marrow.
Pluripotent haematopoietic stem cells are the precusor/progenitor cells of all blood cells.
It takes approximately two days to form a new red blood cell from a hemocytoblast. Red blood cells are also called erythrocytes.
