1:35 PM | Right Turn: Autism, Stem Cells and the Tooth Fairy
. This intriguing title is not completely my own. It is a shorter version of Alysson Muotri’s  (UCSD) title from a presentation he gave to the governing Board of the California Institute of Regenerative Medicine on March 13, 2014: “Reversing Autism in the Lab with Help from Stem Cells and the Tooth Fairy.” Dr. Muotri...Read more

8:49 AM | Neurons Definition and Function of Neurotransmitters
Neurons are specialized nerve cells (also see neural cells) and responsible for relaying information via neurotransmitter release. A human brain consists of well over 100 billion neurons. A neuron is the basic building foundation of the human nervous system. Anatomy of a Neuron – VIDEO Messages for other cells or between neurons are sent across synapses in the […] The post Neurons Definition and Function of Neurotransmitters appeared first on Regeneration Center of […]

5:23 PM | Scientist Said He May Have Made STAP Cells—Just As Riken Called Fraud
claimtoken-5350a6c03d880 In light of a press conference yesterday announcing two counts of deliberate misconduct, Riken Institute brass want co-authors of the Nature “acid bath” stem cell papers to retract one—after appeal. But two developments may complicate this. First, lead author Haruko Obokata refuses to accept it.Read more about Scientist Said He May Have Made STAP Cells—Just As Riken Called FraudComments

5:28 AM | Potyviruses: bad enough to infect but good enough not to kill
RNA viruses have evolved a whole arsenal of post-translational mechanisms to overcome the inherent limitations of their small, relatively simple genome – they must assure the spatio-temporal availability of the building blocks needed for their successful replication, assembly and amplification in the host cell. Hydrolysis of the viral polyprotein by several proteases, encoded by the viral genome, and regulated both by host factors and by viral proteins, is a common virus strategy to […]

8:47 AM | Undifferentiated Cells Definition, Sources and Purpose
Undifferentiated cells refers to a cell that has yet to develop into a particular cell variant. Undifferentiated stem cells are the very basic cells in biology that all other cells derive from. The very first few cells in an embryo are considered undifferentiated. Stem cells are basically undifferentiated cells that have the unique ability to […] The post Undifferentiated Cells Definition, Sources and Purpose appeared first on Regeneration Center of Thailand.

8:30 AM | Discovery of a small protein involved in plant tolerance to water stress
Eukaryotic cells have a system, termed the ubiquitin proteasome system (UPS), that allows protein degradation. This is not only an intracellular garbage disposal system but, by selectively degrading targeted proteins, also controls protein homeostasis, which is vital for plant processes such as embryogenesis and flowering. In a recent study published in Read more...

4:00 AM | A Big Prep and a Short Walk Pays off for ASCB Member Titia de Lange
It was an all-or-nothing moment. Titia de Lange, a newly hired assistant professor at the Rockefeller University, had months of prep work and her entire grant's supply budget in hand as she waited to cross York Avenue, the busy north-south street on Manhattan's Upper East Side that separates Rockefeller from Memorial Sloan-Kettering Cancer Center, where a collaborator was waiting to sequence de Lange's protein distillate. "We walked with all the protein we had from 1,500 liters of HeLa cells," […]

12:58 PM | Can Basic Research Find Safe Shelter from the Budgetary Storms?
Consider it progress but many in Congress are coming around to the idea that the current system for funding the U.S. National Institutes of Health (NIH) and other federal science programs isn't working. Getting everyone on the Hill to agree what should be done to protect research funding is another matter. Now, one senator has come up with a daring new idea on how to shelter biomedical research funding from the budgetary hurricanes blowing through both chambers. Would a biomedical research […]

10:50 PM | A new cosmological coincidence problem?
One of the consequences of the BICEP2 data from last week, should it hold up to scrutiny, and be seen by other experiments (I hope it holds up to scrutiny and is seen by other experiments), is that there is a significant lack of "power" in the temperature anisotropies on large angular scales.What that sentence means is that when you look at the CMB in very large patches on the sky (about the size of the moon and bigger) its temperature fluctuates from patch to patch less than we would […]

Hematopoietic stem cells are variants specifically found in bone marrow or blood in the umbilical cord, which is responsible for the formation of platelets, as well as RBCs (red blood cells) and WBCs (white blood cells). Hematopoietic stem cells (HSc) are also known as Blood cells. These powerful cells are in charge of continuous bodycare and […] The post Hematopoietic Growth Factors and Hematopoiesis Transplantation appeared first on Regeneration Center of Thailand.

6:30 AM | New role of p38 MAP kinases in rheumatoid arthritis
Rheumatoid arthritis is an autoimmune disease that causes chronic systemic inflammation that may affect many tissues and organs, but principally attacks joints. It affects approximately 1% of the population. The clinical symptoms of the disease, synovial hyperplasia and joint destruction, are the consequence of continuous and deregulated release of pro-inflammatory cytokines. In a recent study published in the journal Arthritis and Rheumatism, Ana Cuenda's team, in collaboration with […]

3:22 AM | Infected with Love: A Viral Aphrodisiac in Crickets
Like many other insects, field crickets (Gryllinae) use a courtship song to attract potential mates and initiate mating. A team of researchers headed by Shelley Adamo at Dalhousie University has recently discovered a surprising trigger which speeds up this dating process - a virus. In their recent article “A viral aphrodisiac in the cricket Gryllus texensis” published in the Journal of Experimental Biology, the researchers found that a pathogenic insect virus (iridovirus) is able to […]

4:55 PM | The Good Words—Bench Bloggers
Supposedly, 200 million people are out there blogging. Unsurprisingly, many of them are working scientists, some are even cell biologists. It's one of the encouraging features of the evolving science writing ecosystem that scientists can write directly about their lives and their work. Some scientists use their blogs as podiums, some as pulpits, and some as stand-up mikes for riffs on the day-to-day research world of dirty glassware, shaky funding, and bad behavior.

11:17 AM | Cytokine Function as Immunoregulation Agents|Interleukin Therapy
Regenerative Medicine Blog and Stem Cell News The medical term of “cytokine” is derived from a blending of two Greek words – “cyto” or cell and “kinos” which means movement. Cytokine molecules exist in peptides, proteins and glyco-proteins (sugar attached). The cytokines cells come form a sizable family of molecules that can be classified into several different categories due to them not […] The post Cytokine Function as Immunoregulation […]

10:00 AM | Discovery of a mechanism that governs cilium size
Many mammalian cells bear primary cilia on their surface, involved in a variety of physiological processes such as sensing of the environment, cell growth, and development. Several pathologies such as hydrocephalus, anosmia (loss of olfaction) or retinitis pigmentosa are caused by defects in these organelles. The published results show that not only kinase-dependent activation of HDAC6 but also its distribution determines substrate selection of the deacetylase. The Dido3 protein […]

5:07 PM | The human machine: finely-tuned sensors
The previous post in this series can be found here.All good machines need sensors, and we are no different. Everyone is familiar with the five classic senses of sight, smell, touch, taste, and hearing, but we often forget just how amazingly finely tuned these senses are, and many people have little appreciation of just how complex the biology behind each sense is. In this week's post, I hope to give you an understanding of how one of our senses, smell, functions and how, in light of recent […]
