← Life Sciences & MedicineA researcher treats hematopoietic stem cells with specific cytokines. Which consequence follows from these signals influencing gene expression programs?
A)Increased proteasome degradation targeting p53
B)Enhanced glycolysis for increased ATP production
C)Telomere shortening and cellular senescence onset
D)Directed differentiation along specific blood lineage✓
💡 Explanation
Cytokines act as niche factors, guiding stem cell differentiation via specific signaling pathways. These signals influence gene expression patterns, therefore directed differentiation along specific blood lineages occurs, rather than other outcomes linked to energy production, apoptosis resistance, or aging.
