Nano-sized materials possess uniqueness in their properties and designs as compared to their bulk counterparts. For this reason, they have attracted a great deal of attention from the scientific community. Nanocomposite is a composition having a dispersed material that has one or more dimensions, such as length, width and thickness, in the nanometer size range. The nano-sized materials have eme...
Encapsulation of Protocorm of Cymbidium bicolor Lindl. for Short-Term Storage and Germplasm Exchange
The present study describes the encapsulation of protocorm of Cymbidium bicolor Lindl. from 60 days-old in seed cultures for short- term conservation and propagation. Various concentrations and combinations of gelling matrix (sodium alginate) and complexing agents (calcium chloride) were tested to prepare uniform beads. The ideal beads were ob- tained through a combination of 3% sodium alginate...
In an attempt to repair chondral lesions in a joint, different methods are under investigation that use human chondrocytes for transplantation. In our laboratory we have used the alginate system to study the effects of various growth factors and cytokines on human chondrocyte metabolism [1]. Evidence is accumulating that Insulin-like growth factor-I (IGF-I) may play a key role in maintaining th...
background: while articular chondrocytes are among those appropriate candidates for cartilage regeneration, the cell dedifferentiation during monolayer culture has limited their application. several investigations have indicated the usefulness of alginate, but the topic of proliferation and differentiation of chondrocytes in alginate culture has still remained controversial. methods: rat articu...
In the present study, beads of alginate, alginate-biuret and alginate-urea, were synthesised for removal Ni(II) Zn(II) metal ions from aqueous solution (in single in bimetallic component solution). The properties sorbents investigated by pHpcz, ESEM-EDX ESEM. modelling experimental data demonstrate that PSORE equation fits well kinetic profiles, while Langmuir also Sips models correspond to res...
purpose: The aim of the present study is to understand if EBs can generate neural rosette upon co-culture with chick embryo somites. Materials and Methods: The mouse ES cells, line Royan Bl, were cultured in hanging drops to induce embryoid bodies (EBs) formation. Somites were isolated from the chick embryos and then embedded in alginate solution. Finally, alginate beads containing somites were...
