En apoyo a la investigación sobre células raíz embrionarias

La mayoría de las células de nuestros cuerpos tienen una vida corta y una misión específica que cumplir. Las células raíz, que se encuentran en muchos órganos, desde la piel hasta la médula ósea, son diferentes. Los “ancestros” de las células comunes, son capaces de regenerarse indefinidamente. Dadas las señales bioquímicas correctas, estas células se pueden dividir y transformarse en distintos tipos de células según las necesidades.

Tal versatilidad significa que las células raíz tienen el potencial para regenerar tejidos de órganos dañados y ofrecer tratamientos nuevos y sorprendentes para una gama de enfermedades que en la actualidad son devastadoras. En efecto, las células raíz podrían tal vez permitir que el ser humano “desarrollara órganos nuevos” para remplazar los enfermos, con lo que existiría la posibilidad de nuevas terapias celulares.

Con base en investigaciones de células similares en ratones, los científicos prevén que las células raíz podrían utilizarse para reponer médula ósea en los pacientes que sufren de cáncer, para producir células pancreáticas que alivien la diabetes, o células neuronales para tratar la enfermedad de Parkinson, la de Alzheimer y varios trastornos cerebrales y de la espina vertebral.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
