Researchers at the RIKEN Omics Science Center (OSC) have successfully developed and demonstrated a new experimental technique for producing cells with specific functions through the artificial reconstruction of transcriptional regulatory networks. As an alternative to induced pluripotent stem cells, the technique promises to enable faster and more efficient production of functional cells for use in cancer therapy and a variety of other areas. Starting with the first-ever production of...

Finding promises to streamline creation of therapeutic cells Despite the promise associated with the therapeutic use of human stem cells, a complete understanding of the mechanisms that control the fundamental question of whether a stem cell becomes a specific cell type within the body or remains a stem cell has–until now–eluded scientists. A University of Georgia study published in the March 2 edition of the journal Cell Stem Cell, however, creates the first ever blueprint...

Scientists have found a way to generate and maintain stem cells much more efficiently by amplifying the effect of an essential protein Scientists have found a way to generate and maintain stem cells much more efficiently by amplifying the effect of an essential protein. Researchers from Denmark, Scotland and the USA have created synthetic versions of a protein, which manipulates adult cells — such as skin cells — so that they can subsequently revert to an earlier, embryonic...

Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons. The multiple successes of the direct conversion method could refute the idea that pluripotency (a term that describes the ability of stem cells to become...

Human stem cells capable of giving rise to any fetal or adult cell type are known as pluripotent stem cells. It is hoped that such cells, the most well known being human embryonic stem cells (hESCs), can be used to generate cell populations with therapeutic utility. In this context, neural derivatives of hESCs are being tested in clinical trials. However, Natalie Lefort and colleagues, at the Institute for Stem cell Therapy and Exploration of Monogenic diseases, France, have now generated...

Stem Cells Could Help Save The Snow Leopard
2012-01-23 12:15:34

The survival of the endangered snow leopard is looking promising thanks to Monash University scientists who have, for the first time, produced embryonic stem-like cells from the tissue of an adult leopard. Never before have induced pluripotent stem (iPS) cells, which share many of the useful properties of embryonic stem cells, been generated from a member of the cat family. The breakthrough raises the possibility of cryopreservation of genetic material for future cloning and other assisted...

Stanford University School of Medicine investigators have shown that iPS cells, viewed as a possible alternative to human embryonic stem cells, can mirror the defining defects of a genetic condition – in this instance, Marfan syndrome – as well as embryonic stem cells can. An immediate implication is that iPS cells could be used to examine the molecular aspects of Marfan on a personalized basis. Embryonic stem cells, on the other hand, can't do this because their genetic contents...


Word of the Day
siliqua
  • A Roman unit of weight, 1⁄1728 of a pound.
  • A weight of four grains used in weighing gold and precious stones; a carat.
  • In anatomy, a formation suggesting a husk or pod.
  • The lowest unit in the Roman coinage, the twenty-fourth part of a solidus.
  • A coin of base silver of the Gothic and Lombard kings of Italy.
'Siliqua' comes from a Latin word meaning 'a pod.'
