Studies on the process of shoot tip in vitro culture and plantlet regeneration of Liriope spicata var.prolifera showed that the process of induction propagation and differentiation of callus from the shoot tip was observed on the MS medium with 2.0 mg/L 6-BA and 0.2~0.5 mg/L NAA. The rooting of differentiated shoots and plantlet regeneration could be finished on the 1/2MS medium with 0.5 mg/L NAA.
By using plant tissue culture technology and HPLC techniques, the biotransformation of 9 active chemicals by the 3 in vitro culture systems of Rheum palmatum was studied.
The stable cell suspension cultures of Scutellaria baicalensis Georgi was obtained by plant tissue culture. The optimum liquid MS medium was NH4+/NO3-30/40 mmol/L,Ca2+ 3 mmol/L,pH 5.4,sucrose 3%.
The levels of hCG,P and E_2 in the chorionic and decidual tissue cultures treated with lilopristone were lower than those treated with mifepristone(P<0.01 to P<0.05) while PGF_(2α) levels were higher than those treated with mifepristone(P<0.01 to P<0.05).
The tolerance to NaCl of tissues culture calli of Populus clones(NL 80105,NL 80106,and NL 80117) and Pinus elliottii was studied The results were as follows:(1) MS medium with 2 0 mg·kg -1 of 2,4 D and 0 5 mg·kg -1 KT was suitable for tree calli in tissue cultures;
Results: Mifepristone or lilopristone at various concentrations used significantly decreased the levels of hCG,P and E_2(P<0.01 to P<0.05) and increased the levels of PGF_(2α)(P<0.01) in the chorionic and(decidual) tissue cultures.
2066 fermentation fluids from actinomyces have been screened in micro-well tissue cultures for their inhibition effects against herpes simplex virus I (HSV-I)SM44 and influenza virus A Yue-Fong 72-243 (H3N2).
It was found that the viability of VSMCs on the modified PLLA films were greater than that on original PLLA films and tissue culture plastic after ten days culture (p >amp;lt; 0.05).
To develop a rabbit corneal endothelial (RCE) cell line, in vitro culture of RCE cells was initiated from Oryctolagus curiculus corneas and a novel RCE cell line was established in this study.
Plant tissue culture systems were established on Murashige and Skoog (MS) media supplemented with various plant growth regulators using mature embryos of sunflower.
Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application.
The infection of tobacco, nightshade, rice plants, and their tissue cultures with the cyanobacteria-bacteria associative microsymbiont complexes (AMC) isolated from natural syncyanoses (the ferns Azolla pinnataand Azollasp.
We developed a mathematical model for assessment of karyotype incidence and the "sex ratio" of spontaneous abortions, taking into account risk of maternal cell contamination in extraembryonic tissue cultures.
