21. HEMATOPOIESIS (Cellular lineage- growth factors)
• Proses pembentukan sel darah  Hematopoiesis
Dapat dibedakan menjadi:
 Erythropoiesis
Proses pembentukan erythrocytus/sel darah merah
 Granulopoiesis
Proses pembentukan leucocytus/sel leucocyte
(darah putih)
 Monocytopoiesis
Proses pembentukan monocytus/lymphocytes
 Megakaryocytopoiesis
Proses pembentukan megakaryocytus

1. Growth factors (faktor pertumbuhan)
2. Faktor lingkungan (Micro)
Growth factors
 Granulocyte (G-CSF)
 menstimulasi pembentukan leucocytus
. Granulocyte+macrophage (GM-CSF)
Macrophage (M-CSF)
 Interleukin 3
 menstimulasi pembentukan sel myeloid
 Erythropoietin (EPO)
 menstimulasi pembentukan sel darah merah
