PPSC’s initially divide and differentiate into multipotential haematopoietic stem cells of one of two lineages: myeloid progenitors (granulocytes, erythroblasts, [[Macrophages|macrophages]] and megakaryocytes) or lymphoid progenitors.

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 platelets ([[Thrombopoiesis|Thrombopoiesis]])
