Input: Consider Input: In pregnancy, trophoblast invasion and uterine spiral artery remodelling are important for lowering maternal vascular resistance and increasing uteroplacental blood flow. Impaired spiral artery remodelling has been implicated in pre-eclampsia, a major complication of pregnancy, for a long time but the underlying mechanisms remain unclear. Corin (also known as atrial natriuretic peptide-converting enzyme) is a cardiac protease that activates atrial natriuretic peptide (ANP), a cardiac hormone that is important in regulating blood pressure. Unexpectedly, corin expression was detected in the pregnant uterus. Here we identify a new function of corin and ANP in promoting trophoblast invasion and spiral artery remodelling. We show that pregnant corin- or ANP-deficient mice developed high blood pressure and proteinuria, characteristics of pre-eclampsia. In these mice, trophoblast invasion and uterine spiral artery remodelling were markedly impaired. Consistent with this, the ANP potently stimulated human trophoblasts in invading Matrigels. In patients with pre-eclampsia, uterine Corin messenger RNA and protein levels were significantly lower than that in normal pregnancies. Moreover, we have identified Corin gene mutations in pre-eclamptic patients, which decreased corin activity in processing pro-ANP. These results indicate that corin and ANP are essential for physiological changes at the maternalfetal interface, suggesting that defects in corin and ANP function may contribute to pre-eclampsia.

Output: Role of corin in trophoblast invasion and uterine spiral artery remodelling in pregnancy

Input: Consider Input: Pluripotent cells arise within the inner cell mass (ICM) of mammals and have the potential to generate all cell types of the adult organism through a process of commitment and ordered differentiation. Despite many decades of investigation, the mechanisms that guide and stabilise cell fate choice as well as those that can be engineered to promote its reversal, remain only partially resolved. Reprogramming of somatic cells towards a pluripotent-like state can be achieved by several different experimental routes including nuclear transfer, the supply of a defined cocktail of transcription factors, or by fusing somatic cells with a pluripotent stem cell partner. These approaches have been used to demonstrate the remarkable intrinsic epigenetic plasticity of many terminally differentiated cell types, as well as to define the factors that are required for pluripotent conversion. In this review we summarise some recent advances using cell fusion-based studies to better understand the basis of pluripotency and the epigenetic mechanisms that promote cell type inter-conversion.

Output: Reprogramming somatic cells towards pluripotency by cellular fusion.

Input: Consider Input: Embryonic-like stem cell (ELSC), expressing part of surface markers of human embryonic stem cells, may be a better candidate for cell therapy of degenerative muscular disease than mesenchymal stem cell (MSC). We isolated ELSC and MSC from bone marrow, respectively, and compared their differences in the characteristics and the capacity of myogenic differentiation. Results showed that ELSC could be isolated successfully from 3 adult bone marrow samples by using serum-free medium with 10ng/ml basic fibroblast growth factor (bFGF). At the same cell density, MSC could also be isolated from the same samples by using DMEM/F12 medium containing 10% new cattle serum. However, ELSC appeared as small, morphologically slenderer, upregulated expression of SSEA-4 and ultramicroscopically more immature than MSC derived from the same samples. Immunofluorescent staining and RT-PCR analysis showed ELSC weakly expressed Oct-4, Nanog-3 and Sox-2. Moreover, ELSC and MSC could be induced into long, multinucleated fibers expressing myogenin and myosin heavy chain (MHC) in myogenic differentiation medium, but by day 10, proportion of multinucleated fibers positive for MHC was respectively 25.0%+/-6.9% and 13.8%+/-7.6% in ELSC and MSC culture. These data suggest that bone marrow derived ELSC represent an ideal candidate for cell therapy of degenerative muscular disease.
Output: Embryonic-like stem cell derived from adult bone marrow: immature morphology, cell surface markers, ultramicrostructure and differentiation into multinucleated fibers in vitro.
