HSC Mesenchymal stem cells have become attractive tools for bioengineers, but some scientists haven’t given up on their regenerative potential Stem cell scientists had what first appeared to be an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in the bone marrow, can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair. Unfortunately, the results of these...

The Rockefeller University About seven days after conception, something remarkable occurs in the clump of cells that will eventually become a new human being. They start to specialize. They take on characteristics that begin to hint at their ultimate fate as part of the skin, brain, muscle or any of the roughly 200 cell types that exist in people, and they start to form distinct layers. Although scientists have studied this process in animals, and have tried to coax human embryonic...

Wellcome Trust Sanger Institute Cell's unique mutations used to trace history back to its origins in the embryo Researchers have developed new methods to trace the life history of individual cells back to their origins in the fertilized egg. By looking at the copy of the human genome present in healthy cells, they were able to build a picture of each cell's development from the early embryo on its journey to become part of an adult organ. During the life of an individual, all cells...

A new study released today in STEM CELLS Translational Medicine suggests a new way to produce endothelial progenitor cells in quantities large enough to be feasible for use in developing new cancer treatments. Durham, NC (PRWEB) June 27, 2014 A new study released today in STEM CELLS Translational Medicine suggests a new way to produce endothelial progenitor cells in quantities large enough to be feasible for use in developing new cancer treatments. Endothelial progenitor cells (EPCs) are...

RIKEN Stem cells have the unique ability to become any type of cell in the body. Given this, the possibility that they can be cultured and engineered in the laboratory makes them an attractive option for regenerative medicine. However, some conditions that are commonly used for culturing human stem cells have the potential to introduce contaminants, thus rendering the cells unusable for clinical use. These conditions cannot be avoided, however, as they help maintain the pluripotency of...

Do Salamanders Hold The Key To Limb Regeneration?
2014-06-20 03:50:11

University College London The secret of how salamanders successfully regrow body parts is being unraveled by UCL researchers in a bid to apply it to humans. For the first time, researchers have found that the 'ERK pathway' must be constantly active for salamander cells to be reprogrammed, and hence able to contribute to the regeneration of different body parts. The team identified a key difference between the activity of this pathway in salamanders and mammals, which helps us to...

Rice University Rice University scientists apply new theory to learn how and why cells differentiate How does a stem cell decide what path to take? In a way, it’s up to the wisdom of the crowd. The DNA in a pluripotent stem cell is bombarded with waves of proteins whose ebb and flow nudge the cell toward becoming blood, bone, skin or organs. A new theory by scientists at Rice University shows the cell’s journey is neither a simple step-by-step process nor all random....

Rhithrogena germanica
2013-07-09 15:10:58

Rhithrogena germanica, known as the March brown mayfly in in the British Isle, is a species of mayfly that can be found throughout northern and central areas of Europe. Its range includes the River Tweed in England, Hesse in Germany, Denmark, Poland, and France. It was first described by Alfred Edwin Eaton, who studied a male specimen from the River Rhine. Rhithrogena germanica begins its lifecycle in the larval stage, as a water dwelling naiad that is typically found in fast flowing,...

Vase Tunicate, Ciona intestinalis
2014-01-12 00:00:00

The Vase Tunicate (Ciona intestinalis) is a species of sea squirt widely distributed in Northern European waters. It has also spread to other parts of the world, where it is considered invasive. It grows in dense aggregations on any floating or submerged substrate, especially on artificial structures like pilings, aquaculture gear, floats and boat hulls. It is found in the lower intertidal and subtidal zones. Sea squirts have been long recognized as being possibly the closest invertebrate...

The Zebrafish (Danio rerio) is a tropical fish belonging to the minnow family (Cyprinidae). It is a popular aquarium fish, where it is frequently sold under the trade name Zebra danio, and is also an important model organism. Characteristics The zebrafish arose in the Ganges region in Eastern India and is also native to Pakistan, Bangladesh, Nepal and Myanmar. It commonly inhabits streams, canals, ditches, ponds and slow-moving to stagnant water bodies, including rice fields. The...

The Orthoptera are an order of insects with incomplete metamorphosis, including the grasshoppers, crickets, locusts, and katydids. Many insects in this order produce sound (known as stridulation) by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. Their ears, located in the front legs, are interconnected in such a way that they are able to locate each other by sound. Characteristics Orthopterans have two pairs of wings - the...

The Ghost Shrimp, Pestarella tyrrhena is a species of thalassinidean crustacean that dwells in shallow, sandy tunnels of the ocean floor in the Mediterranean Sea and northern Atlantic Ocean. Initially, the crustacean derived its name from the Tyrrhenian Sea where it inhabited. The crustacean was called formerly Callianassa tyrrhena, but current common terminology for the species is Ghost Shrimp or Mud Shrimp. Fishermen in the Mediterranean have used it as bait for at least 200 years...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
