  • 功能：
    Stimulates the proliferation of early hematopoietic cells by activating FLT3. Synergizes well with a number of other colony stimulating factors and interleukins.
  • 基因功能参考文献：
    1. our study demonstrates that Flt3L acts as an important regulator of ILCs lymphopoiesis and it can be used as a tool to expand and study ILCs precursors in the BM. PMID: 29317685
