Study Casts Doubt On Heart Regeneration In Mammals
2014-04-04 15:19:02

Cell Press The mammalian heart has generally been considered to lack the ability to repair itself after injury, but a 2011 study in newborn mice challenged this view, providing evidence for complete regeneration after resection of 10% of the apex, the lowest part of the heart. In a study published by Cell Press in Stem Cell Reports on April 3, 2014, researchers attempted to replicate these recent findings but failed to uncover any evidence of complete heart regeneration in newborn mice...

Stowers team reports genome-wide analysis of genes that drive cell division in a multicellular organism In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells. This process, called mitosis, is visually stunning to observe under a microscope. Equally stunning to cell biologists are the preparatory steps cells take to ensure that the process occurs safely....

Rare, very small embryonic-like stem cells (VSELs) isolated from human adult tissues could provide a new source for developing regenerative therapies to repair complex tissues damaged by disease or trauma. The ability of these most-primitive, multipotent stem cells to differentiate into bone, neurons, connective tissue, and other cell types, and the proper criteria for identifying and isolating VSELs, are described in two articles in Stem Cells and Development, a peer-reviewed journal from...

Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding, described in Nature Communications, will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis (ALS). The new method involves adding critical signaling molecules to precursor cells a few days earlier than previous methods...

Big Breakthrough In Stem Cell Manufacturing Technology
2014-04-01 13:07:09

University of Nottingham Scientists at The University of Nottingham have developed a new substance which could simplify the manufacture of cell therapy in the pioneering world of regenerative medicine. Cell therapy is an exciting and rapidly developing area of medicine in which stem cells have the potential to repair human tissue and maintain organ function in chronic disease and age-related illnesses. But a major problem with translating current successful research into actual products...

Japanese Scientist Falsified Claims On Groundbreaking Stem Cell Research
2014-04-01 08:43:26

Lawrence LeBlond for redOrbit.com - Your Universe Online Less than three months after a rising Japanese scientist made claims of a significant stem cell breakthrough, new evidence has come forward that confirms the findings of the groundbreaking study were falsified. Haruko Obokata, the lead author of a study published in the journal Nature in January, claimed that stem cells could be created by dipping blood cells into acid, potentially leading to hope in growing Stap...

regeneration of zebrafish fin
2014-03-30 06:37:34

Instituto Gulbenkian de Ciencia The reason why some animals can regenerate tissues after severe organ loss or amputation while others, such as humans, cannot renew some structures has always intrigued scientists. In a study now published in PLOS ONE, a research group from Instituto Gulbenkian de Ciência (IGC, Portugal) led by Joaquín Rodríguez León provided new clues to solve this central question by investigating regeneration in an adult vertebrate model: the zebrafish. It was known...

As a result, the neighbors become harder to kill Cells usually self-destruct when irreparable glitches occur in their DNA. Programmed cell death, or apoptosis, helps insure that cells with damaged DNA do not grow and replicate to produce more mutated cells. Apoptosis thereby helps protect and insure the survival of the organism. At the GSA Drosophila Research Conference, TinTin Su, Ph.D., will report that a dying Drosophila melanogaster larvae cell alerts neighboring cells that they are...

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...
