BACKGROUND: Previous studies demonstrated that eucommia bark can promote bone marrow stern cells (BMSCs) differentiated into osteoblasts, but relative mechanism is poorly understood. OBJECTIVE: To investigate the effects of eucommia bark water/methanol extracts on expressions of osteopontin (OPN) and osteoprotegedn (OPG) in rat BMSCs. METHODS: Totally 2 g eucommia bark powder were added into water or methanol to 16 mL and oscillated for 1 hour at room temperature. After soaked overnight, both extracts were centrifuged at 15 000 r/min for 10 minutes. Water extract was obtained from supernatant in water soaked powder. In methanol soaked powder, methanol extracts was obtained by concentrated supernatant in vacuo and resolved using 16 mL water. Water and methanol extracts were then filtered by 0.22 μm membrane, and conserved at -20℃. Six SD rats, aged 2 months, were selected, and the 3~(rd)passage of BMSCs were induced by water or methanol extracts with dilution of 1 × 10~(-2), 1 × 10~(-3), 1 × 10~(-4) and 1 × 10~(-5), respectively. PBS was added in the negative control group. All cells were cultured for 6 days. Expressions of OPN and OPG was measured by immunocytochemistry at 6 days with induction. The expression of OPN and OPG induced by water and methanol at 1 ×10~(-3) and 1×10~(-4) dilution was detected by RT-PCR. RESULTS AND CONCLUSION: Immunocytochemistrical results indicated that both water and methanol extracts of eucommia bark simulated OPN and OPG expression, in particular with dilution of 1×10~(-4). The methanol extracts had a stronger effect than water extract, but the expression of OPG did not change obviously. RT-PCR demonstrated that at the 3rd day of inducement, the level of OPN expression induced by water extract was higher than that of methanol extract, and no OPG expression was detected. Osteogenic differentiation of rat MSCs induced by eucommia bark water/methanol extracts relates to stimulating expression of OPN, which has no correlation to OPG. OPN expression induced by water extract is early than that of methanol extract.

Simple sequence repeat (SSR) was used to investigate the genetic diversity and structure of Dendrobium officinale. A total of 15 primer pairs with stable and repeatable polymorphism were screened out from 60 SSR primer pairs developed by the method of microsatellite enrichment by magnetic beads. Forty-eight samples of Dendrobium officinale were analyzed in genetic polymorphism. These loci were polymorphic and displayed 3 to 9 alleles per locus with a mean number of 6.1. The observed and expected heterozygosities ranged from 0.60 to 0.85 and from 0.49 to 0.85 respectively. The polymorphic information content (PIC) of each SSR locus varied from 0.437 to 0.829 with an average of 0.702. Fifteen primer pairs were used in Dendrobium cross-species amplification and totally 13 primer pairs were proved to have the transferability in D. officinale related species. In addition, 500 tissue culture plantlets of D. officinale were tested for purity identification by means of PCR amplification with four SSR primer pairs. The results showed that SSR technique is a feasible, simple and inexpensive method for determining adulterants in germplasm identification.

Objective To breed a guinea pig inbred strain and set up a method for detection of the microsatellite markers of genetic structure in guinea pigs. Method Using inbreeding methods we try to breed the Zmu-1:DHP inbred strain. With 15 pairs of polymorphism microsatellite primers, the genetic homozygosity of Zmu?1:DHP inbred strain,Zmu?1:DHP outbred strain and Zmu?2:DHP inbred strain ( as control) were examined by PCR. Results After breeding for 13 years, 8 sublines of Zmu?1:DHP inbred strain ( >20 generations) were bred. After identification, the gene frequency of the second subline of Zmu?1:DHP inbred strain was 86. 7%,higher than Zmu?1:DHP outbred strain (6. 7%) and Zmu?2:DHP inbred strain (66. 7%). The average number of loci of Zmu?1:DHP inbred strain was 1. 13,lower than that of Zmu?1:DHP outbred strain (2. 47%) and Zmu?2:DHP inbred strain (1. 33%). The genotypic frequency of Zmu?1:DHP in?bred strain was also higher than that of the other strains. The gene types of Zmu?1:DHP inbred strain were included in the genes of Zmu?1:DHP outbred strain, but Zmu?1:DHP inbred strain was short of 2 characteristic genes. The gene homozy?gous rates of 8 sublines of Zmu?1:DHP inbred strain were different with each other,among them, those of the 2nd and 8th sublines were higher than others. Conclusions There are both homozygosity and specificity in the Zum?1:DHP inbred strain and Zum?1:DHP outbred strain. The second Zum?1:DHP subline becomes a new inbred strain guinea pig. It is es?sential that the subline with the characteristic property is screened from these sublines. The guinea pigs of black Zmu?2:DHP inbred strain carrying microsatellite markers not present in the white strains, may carry optimal genes related with hair color properties.
