What are dendritic cells?
Dendritic cells are immune cells that play a critical role in linking the innate and adaptive immune systems.
How does lentiviral transduction work?
Lentiviral transduction involves using lentiviruses to introduce shRNA into cells, leading to stable gene knockdown.
What is the significance of transcription factors in DC development?
Transcription factors regulate gene expression and are crucial for the differentiation and function of dendritic cells.
What are iHSPCs?
Immortalized hematopoietic stem and progenitor cells (iHSPCs) are cell lines that can differentiate into various blood cell types.
What role does FLT3 ligand play in this protocol?
FLT3 ligand is a growth factor that supports the survival and proliferation of hematopoietic progenitor cells.
