High-yield details
Tip: cytokines are not perfectly exclusive; the map shows the classic dominant driver tested in exams.
The “dominant driver” shortcuts worth recalling at the bedside and in MCQs.
Early multipotent support: stem cell factor (SCF), FLT3 ligand, and IL-3. Cytokines influence survival/proliferation; transcription factors and marrow niche signals refine commitment.
