FMS Like Tyrosine Kinase 3 Ligand (Flt3L)

The Flt3l is a small molecule that acts as a growth factor that increases the number of immune cells by activating the hematopoietic progenitors. It also induces the mobilization of the hematopoietic progenitors and stem cells in vivo which may help the system to kill cancer cells.FLT3L is crucial for steady-state pDC and cDC development . A lack of FLT3L results in low levels of DCs.Flt3 ligand (FL) is a hematopoietic four helical bundle cytokine. It is structurally homologous to stem cell factor (SCF) and colony stimulating facor 1 (CSF-1). In synergy with other growth factors, Flt3 ligand stimulates the proliferation and differentiation of various blood cell progenitors.
