  • Meanwhile, adult stem cell research is pushing the science ahead at a steady clip. (pharmexec.com)
  • These moral perils are surely not a reason to oppose adult stem cell research, which deserves vigorous and expanded public support. (eppc.org)
  • Media for mammalian cultures in particular are notoriously expensive, and traditional cell cultures can be highly sensitive to growing conditions. (bioprocessintl.com)
  • During the late 1980s and into the 1990s, plants and plant-derived cell cultures were introduced as alternative cell-culture systems (1, 2). (bioprocessintl.com)
  • Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies. (bioprocessintl.com)
  • Some of those genetically modified plants grew faster, and their sugar production tripled, Joshi reports, making the stems much better suited to producing biofuel. (mtu.edu)
  • The majority of kn1 over-expressing citrus plants grow and develop normally at young seedling stages, similar to those of the wild type plants. (springer.com)
  • It has also been shown that the kn1 mRNA can be transported bidirectionally via phloem cells in plants (Duan et al. (springer.com)
  • The traditional way to clone plants is to dig up the plant and divide the root system into multiple pieces or to take stem cuttings and root them in a misting chamber. (ecolandscaping.org)
  • In 2014 I founded the Maine-based non-profit Wild Seed Project to create a grassroots movement to get lots of people growing native plants from seed. (ecolandscaping.org)
  • In so many ways, I find sowing and growing natives much easier, and with outdoor propagation, the plants are healthy and robust. (ecolandscaping.org)
  • For companies developing genetically engineered plants like SweTree, strict EU regulations also make it hard to develop the technology compared to other parts of the world. (labiotech.eu)
  • For individuals new to native seed sowing, many beautiful native species are easy to grow from seed, but the specific requirements for successful propagation must be understood to assure success. (ecolandscaping.org)
  • I have four decades of experience growing many different native species, and I am also an experienced organic vegetable and herb grower. (ecolandscaping.org)
  • At that time, 78 cell lines met the requirements, yet only 19 of those lines were available for study. (pharmexec.com)
  • Our team is growing all the time, so we're always on the lookout for smart people who want to help us reshape the world of scientific publishing. (intechopen.com)
  • A pack of cells that started the race at the same time would in theory all finish around the same time. (ecwausa.org)
  • However, if we think back to what actually happened to the animal - it died, even if from the cold, the cells in the body would have taken some time to freeze. (wikiquote.org)
  • This time lag would allow for breakdown of the cells, which normally happens when any animal dies. (wikiquote.org)
  • Luckily, the banana companies realised that another variety of banana known as the "Cavendish", unlike the "Gros Michel" type grown in Latin America at the time, was almost completely resistant to Panama disease . (theconversation.com)
  • These data document for the first time that a substantial proportion of wild monkeys in Cameroon are SIV infected and that humans who hunt and handle bushmeat are exposed to a plethora of genetically highly divergent viruses. (cdc.gov)
  • Microfluidics enables single-cell manipulation and analysis, reaction volumes of nano- or picoliters (thereby reducing costs), high-throughput execution of parallel experiments, automated routine liquid handling, integration of multiple biological processes in a single system, and programmability for complex protocols. (nature.com)
  • New research published in Nature Medicine on January 23 highlights yet another challenge: The cell lines currently approved for study under federal funding contain a non-human molecule, the sialic acid Neu5Gc, which elicits an immune response in humans. (pharmexec.com)
  • He also notes that embryonic stem cells are harder to work with than previously believed because 'they tend to form structures that are not completely within our control. (pharmexec.com)
  • Therapeutic monoclonal antibodies (MAbs) mostly are manufactured using bioengineered mammalian cells cultured in a bioreactor for two to three weeks. (bioprocessintl.com)
  • Leukemia (also spelled leukaemia and pronounced /luːˈkiːmiːə/ loo-KEE-mee-ə) is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. (wikipedia.org)
  • The crowding that results from such cells makes the bone marrow unable to produce healthy blood cells resulting in low hemoglobin and low platelets. (wikipedia.org)
  • Saccharomyces cerevisiae cells are either mating type a or mating type (alpha) (alpha) which produce different signalling molecules (pheromones). (futurelearn.com)
  • A blastocyst (cloned or not), because it lacks any trace of a nervous system, has no capacity for suffering or conscious experience in any form - the special properties that, in our view, spell the difference between biological tissue and a human life worthy of respect and rights. (wikiquote.org)
  • The daughter cell receives one of the two nuclei generated via mitosis and a few membrane-bound organelles and then separates, leaving a scar on the surface of the mother cell (Figure 3). (futurelearn.com)
  • There are 4 genetically distinct, but related human bocaviruses. (medscape.com)
  • But no one, including Joshi, wants to genetically modify millions of trees. (mtu.edu)
  • An individual cell deposited on a plate of nutrient-rich jelly would divide and divide until it formed a visible colony of cells, all clones of the original cell. (ecwausa.org)
  • While individual cells have inherent adaptive capability, in certain cases, the adaptation to a given stimulus occurs at the population level via detection and processing of chemical signals. (frontiersin.org)
