Hypericum perforatum L. (St. Johns’ wort) is the most commercially important species of the genus Hypericum and contains a wide range of components including naphthodianthrones, phloroglucinols, tannins, xanthones, phenolic acids and essential oil. In order to establish an efficient protocol for regeneration, the effects of explant type and plant growth regulators on direct and indirect shoot r...

The present study was undertaken to investigate the possibility for developing Efficient Plant regeneration protocol in Vigno mungo L. For this, the effect of Cytokinens on in vitro regeneration from Cotyledonary explants was studied in Black gram (Vigno mungo L.) Hepper Var Vamban-1. The cytokinins used were 6-benzylaminopurine (BAP), Thidiazuron (TDZ), and kinetin (Kn). The regenerated shoots...

How resident stem cells and their immediate progenitors rebuild tissues of pre-injury organization and size for proportional regeneration is not well understood. Using 3D, time-lapse intravital imaging for direct visualization of the muscle regeneration process in live mice, we report that extracellular matrix remnants from injured skeletal muscle fibers, "ghost fibers," govern muscle stem/prog...

Among all organs, the liver has a unique regeneration capability after sustaining injury or the loss of tissue that occurs mainly due to mitosis in the hepatocytes that are quiescent under normal conditions. Liver regeneration is induced through a cascade of various cytokines and growth factors, such as, tumor necrosis factor alpha, interleukin-6, hepatocyte growth factor, and insulin-like grow...

The zebrafish has the capacity to regenerate its heart after severe injury. While the function of a few genes during this process has been studied, we are far from fully understanding how genes interact to coordinate heart regeneration. To enable systematic insights into this phenomenon, we generated and integrated a dynamic co-expression network of heart regeneration in the zebrafish and linke...

I T appears to be highly probable (Br0ndsted, 1953) that starvation retards regeneration in planarians. This finding justifies closer investigation into the importance of various substances for regeneration. Regeneration is of course a very complicated phenomenon and involves chains and networks of innumerable chemical processes. Amongst the substances involved it seems profitable to focus on t...

Numerous animal and human studies have provided evidence supporting the belief that periodontal ligament stem cells (PDLSCs) can be harnessed for regeneration of periodontal tissues. Based on current literature on the use of ex vivo stem culture and associated problems, this case report describes a novel approach of direct application PDLSCs using stem cell assistance in periodontal regeneratio...

Controlling structural organization and signaling motif display is of great importance to design the functional tissue regenerating materials. Synthetic phage, genetically engineered M13 bacteriophage has been recently introduced as novel tissue regeneration materials to display a high density of cell-signaling peptides on their major coat proteins for tissue regeneration purposes. Structural a...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...
