BACKGROUND:Human embryonic stem cels exhibit self-renewal and multi-differentiation potential, and can differentiate into endothelial cels under certaininduction conditions.
OBJECTIVE:To explore induced conditions of the human embryonic stem cels differentiating into endothelial cels and to investigate the effect of vascular endothelial growth factors on theendothelial differentiation of human embryonic stem cels.
METHODS:After resuscitation,passage40 human embryonic stem cel lines H9 weresubjected to suspension culture to prepare embryos, and after 5-day culture,these cels werecultured in attachment medium to differentiate into embryoid bodies,folowed by induction with50 μg/L vascular endothelial growth factors. Passage 2 and 15 embryonic stem cels after induced differentiation weretaken for Dil-Ac-LDL uptake test and immunohistochemical staining, respectively.
RESULTS AND CONCLUSION:After 1-day culture, cord-like or polygonal monolayer cels around embryoid bodies showed bud-like andradialgrowth witharelative rapid speed merging into surrounding colonies; at 2-3 days, the number of suspension cels increased further, but the smal-round cels in the center began to die; at 5 days, embryoid bodies started to passage, and aggregated cels exhibited typical paving stone-like appearance. Moreover, some human embryonic cels after induced differentiation could actively takeupfluorescent labeled LDL,andred fluorescent particlesappeared.Additionaly, passage 15 embryonic stem cels after induced differentiation could express CD31 and FLK-1.These findings suggest that human embryonic stem cels induced by vascular endothelial growth factors can differentiate into endothelial cels.

Aptamers are capable of binding a wide range of biomolecular targets with high affinity and specificity. It has been widely developed for diagnostic and therapeutic purposes. Because of unique three dimensional structures and cell-membrane penetration, aptamers inhibit virus infection not only through binding specific target, such as the viral envelope, genomic site, enzyme, or other viral components, but also can be connected to each other or with siRNA jointly achieve antiviral activity. Taking human immunodeficiency virus and hepatitis C virus as examples, this paper reviewed the effects and mechanisms of aptamers on disturbing viral infection and replication steps. It may provide an insight to the development of aptamer-based new antiviral drugs.

Follicle-stimulating hormone (FSH) is a pituitary glycoprotein hormone that is essential for the development of ovarian follicles and testicular seminiferous tubules. The relatively short half-life of FSH in vivo requires daily injections for more than 10 days that is inconvenient and possibly contribute to the stress perceived by the patients. The goal of the present study was to increase FSH glycosylation, in order to develop a long-acting recombinant FSH. The cDNA of native alpha and beta subunit of human FSH was linked by a sequence with two N-linked glycosylation sites, and the resulted DNA was inserted into pcDNA3.1 vector to generate a recombinant vector of pcDNA3.1-FSH. The pcDNA3.1-FSH was linearized and transfected into CHO-K1, positive transformants were selected by G418 and confirmed by PCR and Western blotting. A single chain recombinant FSH was expressed, with molecular weight of about 49 kDa. The recombinant FSH expression level in CHO-K1 cell strain in serum-free culture was 3 mg/L. Single injection of this recombinant FSH could induce folliculogenesis and ovulation in rats, the efficacy was similar with the commercially available FSH preparation (Folltropin-V) administrated 8 times consecutively. The results suggested a long-acting FSH was produced successfully.
