BioMEMS: forging new collaborations between biologists and engineers

This video describes the fabrication and use of a microfluidic device to culture central nervous system (CNS) neurons. This device is compatible with live-cell optical microscopy (DIC and phase contrast), as well as confocal and two photon microscopy approaches. This method uses precision-molded polymer parts to create miniature multi-compartment cell culture with fluidic isolation. The compartments are made of tiny channels with dimensions that are large enough to culture neurons in well-controlled fluidic microenvironments. Neurons can be cultured for 2-3 weeks within the device, after which they can be fixed and stained for immunocytochemistry. Axonal and somal compartments can be maintained fluidically isolated from each other by using a small hydrostatic pressure difference; this feature can be used to localize soluble insults to one compartment for up to 20 h after each medium change. Fluidic isolation enables collection of pure axonal fraction and biochemical analysis by PCR. The microfluidic device provides a highly adaptable platform for neuroscience research and may find applications in modeling CNS injury and neurodegeneration.     

ECVAM's collaborations with academia

The encouragement of ECVAM's connections with academia through direct collaboration and co-sponsored studentships has resulted in the successful achievement of higher degree qualifications for the young participants, and the development and promotion of alternative methods. So far, 26 students have been registered for higher degrees, of which 13 have been awarded so far, and 16 university departments in nine European countries have been directly involved. When other collaborations are included, the number of ECVAM's interactions with academic institutions rises to 33 departments in eleven countries, including the USA. In addition, through contracts awarded to academic institutions and other forms of collaboration, the prevalidation and validation of alternative methods have been progressed.     

Public-private collaborations and partnerships in stratified medicine: making sense of new interactions

The field of personalised or stratified medicine is evolving alongside the formation of a plethora of public/private partnerships and collaborations. These new institutional forms, or 'social technologies', are varied and emerge in response to several drivers, including the need to draw on a broader base of data inputs relating to genomics, patient behaviour and healthcare system differentiation. This paper discusses some of these drivers of partnerships and collaborations. Although the number of such partnerships is growing, their rationale and basis for collaboration remains unclear. Public-private collaborations are at the core of the set of new life sciences policies in the UK but there is little indication in the policy documents of clear boundaries for these partnerships. In part, this is due to the lack of empirical evidence at the system level for conceptualising what is still a relatively new approach. The collection of evidence in the form of broad evaluations, rather than tightly focused theoretical studies, is more likely to be related back to systems and be of more use for formulating policy rationales.
