Cell Suspension Culture, Somatic Embryo Genetic and Synthetic Seed Production in Different Cultivars of Potato

Plants respond to the attack of pathogens with the oxidative burst, a production of reactive oxygen species (ROS). In this work a cell culture suspension of Phaseolus vulgaris was used to investigate the oxidative burst triggered by a conidia suspension of different races of Colletotrichum lindemuthianum. As a defence response of the cells a two-phase peak was observed with all used races of Co...

Plant cell suspension cultures have several advantages that make them suitable for the production of recombinant proteins. They can be cultivated under aseptic conditions using classical fermentation technology, they are easy to scale-up for manufacturing, and the regulatory requirements are similar to those established for well-characterized production systems based on microbial and mammalian ...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

introduction: nowadays, spermatogonial stem cells (sscs) cultivation has been used by many researchers as an effective tool for infertility treatments. oxidative conditions can be effective on cell proliferation and differentiation of these cells. so, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during sscs in vitro culture. ...

Statement of the Problem A great challenge in periodontal therapy is the regeneration enhancement of osseous defects through applying osteoinductive materials. Demineralized freeze-dried bone allograft (DFDBA) has already been introduced as an allograft with osteoconductive and variable osteoinductive properties. Calcium hydroxide [Ca(OH)2] is an available well-known material in dentistry, whic...

background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...

Transfection of suspension cells has proven to be very difficult using conventional methods. Here, we present a simple and time-saving new transfection protocol wherein cell culture plates coated with chicken egg white are seeded with suspension cells prior to transfection. Our results demonstrate that coupling egg white coatings with commercially available transfection reagents leads to high t...

Introduction: Transplantation of embryonic ventral mesencephalic (VM) dopamine neurons into the striatum is a currently explored therapeutic strategy for treatment of patients with patients with Parkinson's disease (PD). However, this strategy has been limited with poor cell survival, generally ranging from 5-20%. In this study, we investigated the effect of potassium channel blocker of tetr...
