Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE
