The precursor of all lines of blood cells is the hemocytoblast.
hemocytoblast
Erythropoietin
Pleuripotent stem cell
A hemocytoblast, also known as a hematopoietic stem cell, is a multipotent stem cell found in the bone marrow responsible for the production of all blood cell types. It differentiates into various lineages, including red blood cells, white blood cells, and platelets. Hemocytoblasts play a crucial role in the body's ability to regenerate blood and maintain the immune system. Their proper function is essential for overall health and homeostasis.
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).
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.
Hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) are two types of stem cells that can be derived from a hemocytoblast, which is a precursor cell in the bone marrow. HSCs give rise to blood cells, while MSCs have the potential to differentiate into various cell types such as bone, cartilage, and fat cells.
The youngest fossils are typically found in recent sedimentary rock formations or on the surface of the Earth. These fossils are often from organisms that lived within the past few thousand years, such as the bones of mammoths or ancient human remains.
it appears the order goes like this from my A&P Book - Hemocytoblast --> Myeloid Stem Cell --> Myeloblast --> Promyelocyte --> Basophilic myelocite --> Basophilic band cells --> Basophils hope this helps. Anything in the rear of basophils can be a precursor.
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.
It's a stem cell for all blood cells, it's also a process... Ø 1st the cell has to commit to being a RBC and 2nd Ribosome synthesis occurs followed by 3rdhemoglobin synthesis which causes nucleus and organelle ejection which then becomes a mature RBC. The process by which is called "Erythropoiesis," which the kidneys secrete.
