BACKGROUND:Endothelial progenitor cel s, known as the precursor cel s of mature endothelial cel s, have the function of neovascularization and neoendothelialization. Therefore, endothelial progenitor cel s have potential applicability in many fields. Endothelial progenitor cel s can be isolated and cultured from different resources with different methods, but the biological properties and identification of endothelial progenitor cel s stil have controversies.
OBJECTIVE:To explore the methods of isolation and culture of endothelial progenitor cel s from the human peripheral blood and to identify the biological features of endothelial progenitor cel s.
METHODS:Mononuclear cel s were isolated from the human peripheral blood using density gradient centrifugation, and the cel s were resuspended in endothelial basal medium-2 supplemented with the EGM-2-MV-SingleQuots. Then, the cel s were inoculated in human fibronectin-coated culture flasks and cultured in EBM-2MV medium. The morphology of endothelial progenitor cel s was observed. The proliferation potential and surface markers of endothelial progenitor cel s were characterized careful y. Furthermore, the functional properties such as nitric oxide release and tube formation on Matrigel were also evaluated.
RESULTS AND CONCLUSION:While adherent cel s maintained, spindle-shaped cel s formed a cel cluster after 6-7 days. Then, adherent cel s developed to endothelial progenitor cel s with a cobblestone appearance after 2-3 weeks. The endothelial progenitor cel s were confluent with an outgrowth appearance. Endothelial progenitor cel s had a higher proliferation potential compared with human aortic endothelial cel s under the same culture condition. Endothelial progenitor cel s expressed CD31, CD34, CD144 and KDR, displaying an obvious endothelial phenotype. Endothelial progenitor cel s were also found to uptake DiL-acLDL and exhibit lectin binding capability. Furthermore, endothelial progenitor cel s were able to form capil ary tubes on Matrigel and had the ability to release nitric oxide. Therefore, endothelial progenitor cel s can be obtained from the human peripheral blood by density gradient centrifugation and adherent culture. A combining method for the identification of endothelial progenitor cel s should be recommended.

The authors used a microvascular corrosion cast/scanning electron microscopy (SEM) technique to study the microvascular bed of the muscles of the medial pterygoid and masseter in two normal babies. The cast were prepared by perfusing the microvascular vessels with methyl methacrylate. Under SEM, the patterns of branches of the arteriole are: 1. tree like ramifications; 2. symmetrical branching; 3. fine plexiform branching. Moreover, the casts of arterial and venous vessels showed on their surfaces the typical imprint of the endothelial lining. Therefore, the venous vessels could be easily identified by the round nuclei of the endothelial cells of the venous vessels. On the other side, arteries and arterioles displayed spindle shaped nuclear imprints, oriented along the direction of the vessel. The morphological and functional characterization of the imprint of the precapillary sphincter and the two-grade anastomoses of the arcade arteries. The diameter of the capillary casts (mean?SE) was 5.6?1.9?m. Two or three capillaries join together to form a postcapillary venules, sometimes a single capillary reaches a major venous trunk was observed. These structural features were considered to play an important physiological role in the microcirculation in skeletal muscle.

Objective To investigate whether insulin secretion and resistance are different in glucose tolerant and intolerant women with normal pre-pregnant body mass index (BMI) during late pregnancy and to find out if there is association between gestational diabetes and insulin resistance syndrome. Methods On the basis of a 4-hour oral glucose tolerance test (OGTT), 32 gestational diabetes mellitus (GDM) patients, 21 gestational impaired glucose tolerant (GIGT) patients, and 50 normal glucose tolerant (NGT) cases were selected from uncomplicated pregnant women. Those had normal pre-pregnant BMI who had a 1-hour 50-g glucose-screening test (≥7 2 mmol/L), performed between 24～28 weeks of gestation. During the OGTT, several indexes of insulin resistance, insulin secretion, lipid metabolism were measured in addition to the standard glucose measurements. Results Glucose area under curve (GAUC), insulin area under curve (IAUC), insulin sensitivity index (ISI) transformed to natural logarithm and triglycerides (TG) are all significantly higher ( P
