background: the ultrastructural analysis of cultured follicles could direct us to understand subcellular changes during in vitro culture. objective: this study was done to verify the ultrastructural characteristics of in vitro cultured mouse isolated preantral follicles in co-culture system in the presence and absence of leukemia inhibitory factor (lif) materials and methods: mechanically isola...

Leukemia inhibitory factor (LIF) expression in the uterus is essential for embryo implantation in mice. Here we describe the spatial and temporal regulation of LIF signaling in vivo by using tissues isolated from uteri on different days over the implantation period. During this time, LIF receptors are expressed predominantly in the luminal epithelium (LE) of the uterus. Isolated epithelium resp...

Maintaining the pluripotency of mouse ES cells requires both LIF (leukemia inhibitory factor) and unknown factors in serum. The paper from Ying et al. in this issue of Cell shows that BMP (bone morphogenetic protein) can replace serum in this capacity, defining molecular requirements for ES cell self-renewal.

Embryonic stem (ES) cells derived from the inner cell mass (ICM) of blastocysts grow infinitely while maintaining pluripotency. Leukemia inhibitory factor (LIF) can maintain self-renewal of mouse ES cells through activation of Stat3. However, LIF/Stat3 is dispensable for maintenance of ICM and human ES cells, suggesting that the pathway is not fundamental for pluripotency. In search of a critic...

This study reports on leukemia inhibitory factor (LIF) in human articular connective tissues. Biologically active LIF is present in synovial fluids from patients with osteoarthritis and at higher titers in samples from patients with rheumatoid arthritis. Cultured human synoviocytes and articular chondrocytes produced biologically active LIF and synthesized and secreted LIF proteins that migrate...
