The marrow inside the bones of a rabbit's leg contains hematopoietic stem cells (HSCs), which are responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Additionally, there are mesenchymal stem cells (MSCs) in the bone marrow, which have the potential to differentiate into various cell types, including bone, cartilage, and fat cells.
However, despite the presence of these stem cells, rabbits typically do not have the capability to regenerate entire limbs like some other species (e.g., certain amphibians). This limitation may be due to the complexity of limb regeneration, which involves orchestrated cellular and molecular processes that go beyond just the presence of stem cells. Regeneration often requires a specific environment, signaling pathways, and a regenerative blueprint that mammals, including rabbits, do not possess in the same way that certain other organisms do.
