The lymphoid progenitor cell develops from the hemocytoblast in the bone marrow. After development in the bone marrow, the lymphoid progenitor cell migrates to the thymus.
Hemocytoblasts are the stem cells of red and white blood cells. They are located in the bone marrow.
Concept sketch for the hemocytoblast. The hemocytoblast is a cell located in the bone marrow. It is a generalized stem cell for red and white blood cells.
Cholesterol provides stability and support for the plasma membrane. Similar to a phospholipid, it has a hydrophilic and hydrophobic part.
Phospholipids are a type of lipid with a hydrophilic (attracted to water) head and a hydrophobic (repelled by water) tail. Phospholipids are the main component of lipid bilayers of cell membranes.
A chromosome contains the DNA of an organelle. The DNA is wrapped around a histone into a unit called a nucleosome.
