The present study established a mouse model of cerebral infarction by middle cerebral artery occlusion, and monitored the effect of 25 μg/kg leukemia inhibitory factor and (or) basic fibroblast growth factor administration 2 hours after model establishment. Results showed that following administration, the number of endogenous neural stem cells in the infarct area significantly increased, malon...

Programmed death and the identification of growth factors delaying this process in the oligodendrocyte lineage suggest that other cell types provide oligodendrogliotrophins. To determine their source, primary cultures of oligodendroblasts immunopurified from postnatal rat cerebrum were used to screen other cultured neural and non-neural cell types for the release of survival factors into a defi...

Embryo implantation requires both an activated blastocyst and a receptive endometrium. The human endometrium undergoes extensive remodeling in each menstrual cycle to prepare the endometrium for implantation, should conception occur in that cycle. For most of the cycle, the endometrium is retained in a non-receptive or refractory state and it will support implantation of the blastocyst for only...

The solution structure of a murine-human chimera of leukemia inhibitory factor (LIF), a 180-residue cytokine with a molecular mass of 20 kDa, has been determined using multidimensional heteronuclear NMR techniques. The protein contains four alpha-helices, the relative orientations of which are well defined on the basis of long-range interhelical nuclear Overhauser effects. The helices are arran...

Leukemia inhibitory factor (LIF), a secreted cytokine, plays an important role in a wide array of biological processes including inducing differentiation of leukemia cell, inflammatory response, neuronal development, embryonic implantation, stem cell self-renewal and cancer progression, etc. LIF exerts its biological functions mainly through the activation and regulation of JAK/STAT3, AKT, EKR1...
