Chen S-E, Jin B, Li Y-P. TNFregulates myogenesis and muscle regeneration by activating p38 MAPK. Am J Physiol Cell Physiol 292: C1660 –C1671, 2007. First published December 6, 2006; doi:10.1152/ajpcell.00486.2006.—Although p38 MAPK activation is essential for myogenesis, the upstream signaling mechanism that activates p38 during myogenesis remains undefined. We recently reported that p38 activa...

koelreuteria elegans, popularly known as “flame gold” is an ornamental tree. in vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified ms medium. the highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-d from leaf segments. calli transferred in 1.5 mg/l bap resulted in efficient shoot regeneration...

the present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (pgrs) combinations under in vitro conditions. the cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in ms medium containing ba (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and tdz (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...

carnation is considered as the world's third most important cut flower. tissue culture techniques offer suitable method for micropropagation of this ornamental plant. however, one of the problems during in vitro culture of carnation is vitrification. ratio of ammonium to nitrate and agar concentrations in the medium affect this phenomenon. therefore, in this study the effect of these factors on...

For half a century, the limitations of obtaining cross-combinations in lilies because of the incompatibility and incongruity between different varieties have been known. Somatic hybridization is one of the most powerful tools for achieving distant interspecific hybrids. For this purpose, protoplast preparation is a first and important step in efficient system for the regeneration of plants from...

Purpose To explore the neurotrophic factor expression in corneal epithelium and evaluate their effects on the trigeminal ganglion (TG) neurite outgrowth and corneal nerve regeneration in mice. Methods The expression of neurotrophic factors was compared among the intact, regenerating, and regenerated mouse corneal epithelium. Mouse primary TG neurons were treated with the conditioned medium of...

A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...

A simple method was developed to permit albino plant regeneration from anther culture of Hobigonj Boro (Hbj B) IV and Hbj B VI, two local varieties of aromatic indica rice from Bangladesh. Three crucial factors were identified for the albino shoot primordia to change into green plantlets in culture; components of M10 induction medium, callus size (range 0.2-0.4 cm long) and height of shoot prim...
