Human LIF

Human LIF

Human LIF stands for leukemia inhibitory factor. Human LIF is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.


Human LIF may be used for a variety of applications, including:
  • Study of reprogramming and maintenance of human iPS cells to a naive-like stage.
  • Investigation of hematopoiesis, bone and neural development.

Background information

Leukemia inhibitory factor (LIF) is a pleiotropic cytokine, which is critically involved in embryonic development and blastocyst implantation. LIF belongs to the interleukin 6 family and functions through the gp130 activation of STAT3. It is a key factor that prevents embryonic stem cells (ESC) to differentiate, and it is used for maintenance of ES and iPS cultures, especially in mouse cultures. In human, LIF has a role in the reprogramming and mantainance of ES cells to a naive-like stage. Additionally, LIF affects hematopoiesis, neural development, bone and energy metabolism, and inflammation.
