The bone marrow microenvironment, or niche, regulates stem cell survival and differentiation. It consists of cellular elements (endothelial cells, osteoblasts, adipocytes) and extracellular matrix components. Key growth factors, such as erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF), and thrombopoietin (TPO), bind to specific receptors to drive lineage-specific maturation. 2. Approach to the Evaluation of Anemias

Caused by impaired DNA synthesis, usually due to Vitamin B12 or Folate deficiency. Bone marrow evaluation reveals hypersegmented neutrophils and megaloblastic changes in erythroid precursors.

Best practices for venipuncture, skin puncture, and the correct usage of anticoagulants (like EDTA, sodium citrate, and heparin).

Participating in proficiency testing programs to compare internal results with peer laboratories globally, ensuring accuracy and standardized patient care.
