Here's why:
* HSCs are pluripotent: This means they have the ability to differentiate into all the different types of blood cells, including red blood cells, white blood cells (including lymphocytes), and platelets.
* Continuous production: HSCs continuously divide and differentiate to replenish the body's supply of formed elements.
* Found in bone marrow: HSCs reside within the bone marrow, specifically in a microenvironment called the hematopoietic niche.
Therefore, the HSC is the essential starting point for all the formed elements that make up our blood.
