<p>PPSC’s initially divide and differentiate into multipotential haematopoietic stem cells. Multipotential haematopoietic stem cells only have the ability to mature into a single cell lineage, either myeloid progenitors (granulocytes, erythroblasts, [[Macrophages|macrophages]] and megakaryocytes) or lymphoid progenitors. The development of blood cells from the multipotential haematopoietic stem cell into the final mature cell is categorised into:

The development of blood cells from the haematopoietic stem cell into the final mature cell is categorised into:

* The formation of [[Erythrocytes|erythrocytes]] ([[Erythropoiesis|Erythropoiesis]])

* The formation of red blood cells ([[Erythropoiesis|Erythropoiesis]])

* The formation of white blood cells ([[Leukopoiesis|Leukopoiesis]])

* The formation of white blood cells ([[Leukopoiesis|Leukopoiesis]])

* The formation of platelets ([[Thrombopoiesis|Thrombopoiesis]])</p>
