Roots of plantlets of Garcinia indica when cultured for long time on half strength MS medium supplemented with BAP (0.44-2.22 microM) showed production of de novo shoots. Roots attached to mother plant showed more number of shoots, while excised root segments produced lesser shoots. Shoots (0.5-0.8 cm) were transferred to elongation medium consisting of Woody Plant Medium (WPM) supplemented wit...
A transmembrane extracellular matrix receptor of the integrin family, alpha 6 beta 4, is a component of the hemidesmosome, an adhesion complex of importance in epithelial cell-connective tissue attachment (Stepp, M. A., S. Spurr-Michaud, A. Tisdale, J. Elwell, and I. K. Gipson. 1990. Proc. Natl. Acad. Sci. USA. 87:8970-8974; Jones, J. C. R., M. A. Kurpakus, H. M. Cooper, and V. Quaranta. 1991. ...
امروزه کشت سلول ابزار بسیار مفیدی برای پاسخ به بسیاری از سؤالات در زمینهی زیستشناسی محسوب میشود و کاربرد ردههای سلولی روز به روز در حال افزایش است. در این مطالعه تولید کشت اولیه و Cell line ماهی آزاد دریای خزر (Salmo trutta caspius) مورد بررسی قرار گرفت و دو روش کشت اولیه Explant و روش جداسازی آنزیمی به کمک آنزیم تریپسین به منظور تولید کشت اولیه استفاده شد. مهاجرت سلول از بالههای سینهای، ...
Cumin (Cuminum cyminum L.) as a member of the Apiaceae family is one of the most important medicinal plants in Iran. The purpose of this study is to evaluate the effect of plant growth regulators and explant type on callus induction in cumin. For this purpose the cumin seeds (Kuhbanan accession) were disinfected with sodium hypochlorite and alcohol and cultured on MS basal medium. Leaf and hypo...
For centuries, Damask rose has been one of the most popular species of the rose family. Damask rose can be propagated using vegetative methods such as micropropagation. In this research, the use of temporary immersion system was reported for the first time for Damask rose micropropagation. For this reason, a traditional temporary immersion system was designed to facilitate its micropropagation....
St. John’s wort is a traditional medicinal plant that has been used from ancient time for the treatment of neurological and psychiatric diseases. A successful in vitro propagation system for the St. John’s wort was optimized. Different explant type (single node and stem cutting with two nodes) were used in Murashige and Skoog (MS) medium in different concentrations (MS full, 3/4 MS and 2/3 MS)...

BACKGROUND AND PURPOSE Previous studies on the culture of human tenocytes have shown that dexamethasone and triamcinolone reduce cell viability, suppress cell proliferation, and reduce collagen synthesis. However, such cell cultures lack the extracellular matrix and three-dimensional structure of normal tendons, which affects their response to stimuli. We established a human tendon explant cult...
