3-D Petri dish that grows cells in three dimensions A team of Dark brown University biomedical engineers has invented a 3-D Petri dish that can grow cells in three dimensions, a way that promises to quickly and make more realistic cells for medication development and tissue transplantation cheaply. Morgan conceived and created the 3-D Petri dish with a team of Brown learners led by Anthony Napolitano, a Ph silagra .D. Candidate in the biomedical engineering system. Napolitano spent two years perfecting the brand new dish and recently won a $15,000 award from the National Collegiate Inventors and Innovators Alliance to develop the patent-pending technology into a commercially practical product.
In addition, this method does not require any type of additional staining, signifying the density of the biological structures could be observed directly.. 3D images of synapsis between neurons through electron cryotomography A united group of experts from the Max Planck Institute of Biochemistry, in Germany, led by the Spanish physicist Rub-n Fern-ndez-Busnadiego, has were able to obtain 3D pictures of the filaments and vesicles involved with communication between neurons. The method is based on a novel technique in electron microscopy, which cools cells so quickly that their biological structures could be frozen while fully active. We used electron cryotomography, a new technique in microscopy predicated on ultra-fast freezing of cells, in order to study and obtain three-dimensional images of synapsis, the cellular framework in which the conversation between neurons takes place in the brains of mammals Rub-n Fern-ndez-Busnadiego, lead author of the analysis which features on the front cover of this month’s Journal of Cell Biology and a physicist at the Max Planck Institute of Biochemistry, in Germany, tells SINC.
