Question
Three ways that blood cell production is halted in the bone marrow are:
I. Autoimmune disorders: in this condition, the immune cells attack the own body cells.
II. Radiation and chemotherapy treatment: this condition is mainly occur in those person who are taking cancer treatment.
III. Exposure to specific chemicals: In this condition , specific chemical target the red blood cells production in bone marrow.

Colony-stimulating factors are hormones that regulate hematopoiesis. Erythropoietin (Epogen), secreted by the kidney, increases bone marrow erythropoiesis. Granulocyte colony-stimulating factor (G-CSF) stimulates bone marrow leukopoiesis. The most recent colony-stimulating factor is thrombopoietin (TPO), which acts on bone marrow to promote the growth of platelets. These hormones are now produced biosynthetically by recombinant DNA techniques and have shown some impact in the prevention of chemotherapy-induced neutropenia, treatment of cytopenias associated with myelodysplasias, and aplastic anemia. 1. What is erythropoietin? A. A...

2. Multiple myeloma, or blood plasma cancer, is characterized by increased blood vessel formulation in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient’s own stem cells. The measurements were taken immediately prior to the stem cell transplant and at the time the complete response was determined. At the 0.05 level of significance, is there evidence that the mean bone marrow microvessel density is higher...
