The simultaneous activity of osteoblasts and osteoclasts is what causes the reshaping of mature bone as it grows. Bones are defined as rigid organs.
They are made in the bone marrow, but B cells mature in the spleen and T cells mature in the thymus.
No, the spleen does not produce mature T-cells. T-cells mature in the thymus gland, not in the spleen. The spleen's main role is in filtering blood, storing red blood cells, and acting as a reservoir for immune cells.
T cells mature in the thymus, a lymphoid organ located in the chest.
T cells mature in the thymus The T-cells mature in both the thymus gland and the organs known as tonsils.
Undifferentiated means lacking structures typical in mature cells.
I believe it's immature bone because it has the mesenchyme cells, osteoprogenitor cells and osteoblasts. While mature bone has the osteocytes.
Stem cells
Stem cells in a fetus mature in the yellow bone marrow.
It is actually the other way around - mature red blood cells lack a nucleus.

B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow. T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).
Osteocytes.
