HSCI's researchers switch skin cells into pain-sensing neurons

Human noxious stimulus–detecting (nociceptor) sensory neurons produced by converting skin cells with a set of five genes (Credit: Elizabeth Buttermore, PhD).

In a recent publication, Dr Clifford J. Woolf’s team (Harvard Stem Cell Institute (HSCI), USA) described a new experimental technique to produce in vitro pain-sensing neurons directly from mouse and human skin cells. For this, the authors have defined optimal cell culture conditions with five transcription factors to reprogram mouse or human fibroblasts into noxious stimulus–detecting (nociceptor) neurons.

Interestingly, these neural models displayed TRPV1 sensitization to PGE2 (an inflammatory mediator) and Oxaliplatin (a chemotherapeutic drug) modeling the mechanisms related to 1/ in inflammatory pain hypersensitivity and 2/ painful chemotherapy-induced neuropathy.

This in vitro neural cellular model will help the research community to better understand neuropathies and hypersensitivity to pain in fundamental and personalized medicine programs.

5 tech tips to optimize IF microscopy

19/11/2014 by Philippe Fixe, PhD No Comments
Atto-550 labeling in Immuno-Fluorescence tebu-bio

Immunofluorescence (IF) microscopy enables cellular detection, localization and distribution pattern of antigens with fluorescent-conjugated antibodies. When all experimental settings are optimally defined, IF can bring valuable information such as dynamics of protein trafficking, protein co-localisation…

Dundee University logo

Dundee University logoA post-doctoral position is available in Pr. Tomo Tanaka’s lab (Centre for Gene Regulation and Expression – University of Dundee), for up to three years, to study the mechanisms of chromosome segregation in vivo like the in vitro kinetochore–microtubule interaction using TIRF microscopy (Job Reference: LS0530). The closing date is Saturday, January 31, 2015.

To know more about this opportunity, please look at the dedicated web page or visit Pr. Tomo Tanaka’s web site.

Zebrafish – an ideal model for morphogenesis analysis

E-Cadherin (Cdh1) expression in Zebrafish with Genetex antibody (GTX125890 | tebu-bio)

In a recent study, Xiong F. et al. have developed a robust Zebrafish-based model allowing the analysis of the impact of cell shape and division orientation on epithelial development. This model explores possible links between cell shape and division orientation in epithelial diversity.

Among all the research tools used, the team of scientists investigated Cdh1 expression by IHC-Wm with a Genetex antibody, dedicated to Zebrafish studies (cat. nr GTX125890). This unique antibody is available in Europe thorugh tebu-bio for IHC applications (recommended dilutions 1:100-1:1000) including IHC Whole mount (IHC-Wm).

This emphasizes the need for researchers to have access to high quality and validated antibodies focused on Zebrafish model, as described in a previous post, showing the benefits of using such primary antibodies in Zebrafish whole mount IHC staining.
