Scientists have developed a method to visualize defined genomic sequences in living plant cells and demonstrated its ability to reveal dynamic movements of chromosome ends. This method allows the analysis of the spatio-temporal organization of the genome.
An international team of researchers bioengineering human liver tissues uncovered previously unknown networks of genetic-molecular crosstalk that control the organ's developmental processes - greatly advancing efforts to generate healthy and usable human liver tissue from human pluripotent stem cells.
Biomedical engineers have created a lab-grown tissue similar to natural cartilage by giving it a bit of a stretch. The tissue, grown under tension but without a supporting scaffold, shows similar mechanical and biochemical properties to natural cartilage.
The novel method keeps cells alive for multiple weeks, which makes it easier to study them. This makes it possible to, for example, test the action of new drugs and improve stem cell therapies with unparalleled control.
Researchers have developed a method of producing P450 enzymes - used by plants to defend against predators and microbes - in bacterial cell factories. The process could facilitate the production of large quantities of the enzymes, which are also involved in the biosynthesis of active ingredients of cancer drugs.
Scientists for the first time combine organoids with bioengineering. Using small microfilaments, they show improved tissue architecture that mimics human brain development more accurately and allows more targeted studies of brain development and its malfunctions.
Researchers have developed a way to place onto surfaces special coatings that chemically 'communicate' with bacteria, telling them what to do. The coatings, which could be useful in inhibiting or promoting bacterial growth as needed, possess this controlling power over bacteria because, in effect, they 'speak' the bug's own language.
