Science X2 signals: big pharmas, stem cells, mobile MRI

The Institute for the Future‘s X2 project is all about tracing future trends in science and technology As the steward of the Biomedical Sciences and Biotechnology Group I collect signals in these fields on which some forecasts can be based later on. Here are some issues I found future sensitive enough recently: GlaxoSmithKline collaborates with… Continue reading Science X2 signals: big pharmas, stem cells, mobile MRI

Hourglass, a blog carnival devoted to the biology of aging

Finally Chris over at Ouroboros came up with the idea and the quick implementation of Hourglass, a blog carnival devoted to the biology of aging/biogerontology.  For some reason I am not an explicit supporter of blog carnivals – many of my posts were chosen by carnival editors but I never hosted one -, but Hourglass… Continue reading Hourglass, a blog carnival devoted to the biology of aging

The decellularized matrix hack: skipping many steps in tissue engineering

The concept of decellularizing complex organs in cadavers and reseeding the remaining matrix structure with differentiated, stem or progenitor cells, growing in a bioreactor and transplanting back to the organism could turn out to be a real technological shortcut in the field of tissue engineering. It is not a brand new story on the web,… Continue reading The decellularized matrix hack: skipping many steps in tissue engineering

Oxygen control of stem cell niches and cell fates

Did you know that physiological normoxia generally falls in the 2-9% O2 (14.4-64.8 mm Hg) range for most adult cells in vivo? 3 remarkable exceptions are thymus, kidney medulla and most importantly bone marrow which can exist at 1% O2 (7.2 mm Hg). On the other hand, stem and progenitor cells are frequent residents of… Continue reading Oxygen control of stem cell niches and cell fates

The New York Times advertises itself with stem cell research

I’ve just noticed a New York Times paid “stem cell research” Google Adwords ad in my gmail inbox besides the automated “Rejuvenation Research Vol. 11, No. 1, Feb 2008 is now available online” mail. That said, The New York Times is ranking the “stem cell” buzzword high and fishes for layman readers interested in the… Continue reading The New York Times advertises itself with stem cell research

9 year old stem cell trial pioneer dies in Batten disease

This is exactly the type of clinical trial news that should be taken extremely carefully with all due respect and grief. A girl enrolled in a stem-cell trial for a fatal disease has died. In January, the nine-year-old received a brain transplant of neural stem cells derived from fetal tissue. She was one of six… Continue reading 9 year old stem cell trial pioneer dies in Batten disease

induced Pluripotent Stem cells from a 69 year old human: the hidden story?

The successful reprogramming (dedifferentiation) of differentiated human somatic cells into a pluripotent, embryonic stem cell-like state called induced pluripotent stem cells (iPS) using just 4 (and recently 3) introduced transcription factors is the biggest news of current stem cell biology. In the paper published in Cell by the Yamanaka group (Takahashi et al.) the iPS… Continue reading induced Pluripotent Stem cells from a 69 year old human: the hidden story?

Craig Venter and the life extension drive: blogterview questions

One strategy (call it Life Extension Gets Personal) to raise awareness for the idea and technology of healthy life extension is to publicly encourage life extension “coming outs” on behalf of mainstream celebrities. In order to get an academic legitimacy for LE (which is one of the most important aim of Pimm) I am interested… Continue reading Craig Venter and the life extension drive: blogterview questions

Collect and FedEx menstrual stem cells with the C’elle kit: the next flow

It is a somewhat very positive idea that human tissues previously considered as waste products (after filling their essential role in the human body) like the placenta and the umbilical cord are radically reinterpreted as valuable sources of prospective therapies due to the current results of stem cell research and regenerative medicine. Exactly this reinterpretation… Continue reading Collect and FedEx menstrual stem cells with the C’elle kit: the next flow

Where are the quality stem cell blogs?

Honestly, there are not too many good, stem cell related blogs out there. By “good stem cell blogs” I mean blogs that are regularly updated in a niche stem cell related field full with quality science information followed by original opinions and ideas and not just human or algorithmic link blogs. Here are 3 solid… Continue reading Where are the quality stem cell blogs?

Unpublished SENS3 conference report for mainstream scientists!

Recently I wrote a meeting report on the SENS3 conference for a very prestigious science journal, but finally it did not go through the filters. I knew that the chance for publication is small as the journal rarely publish such meeting reports and as it was in many respects an unconventional science conference. The standards… Continue reading Unpublished SENS3 conference report for mainstream scientists!

SENS3 program: Mike Conboy on the immortal strand hypothesis

The immortal strand hypothesis captures stem cell scientists’ imagination these days. According to Thomas Rando The immortal strand hypothesis posits that the propensity of stem cell compartments to give rise to cancer in later life can be minimized if stem cells, during the process of self-renewal, retain those DNA strands with the fewest mutations acquired… Continue reading SENS3 program: Mike Conboy on the immortal strand hypothesis
