April 4: ImageJ Advanced workshop

The Bio-Imaging Utrecht community organizes an ImageJ/FIJI workshop for experienced users on Tuesday the 4th of April. Previous sessions were very well appreciated and they allow you to interact with experts in IJ coding. You can learn image analyses automation and the experts can help you find, tweak and apply the proper plugin(s) for you specific question. It is highly advised for microscopists who use FIJI but have problems overseeing the large analyses possibilities offered by the platform. Register using the form attached here (deadline 17th March) 

New 63x Zeiss objective (NA 1.2) C-Apochromat for LSM880NLO

We are very grateful to the faculty to expand the Zeiss LSM880 NLO functionality with a hi NA (1.2, 63x)  water immersion objective with an automated correction collar. This will allow high resolution imaging on the machine that is currently equipped with a 20x (NA 0.8) and a 32x (NA 0.85) objective. We are waiting for a connector unit to get it working and will be testing its performance shortly afterwards.

New NIKON 20x Plan Achromat objective

A new 20x Plan Achromat VC objective (air) has arrived and is installed on the NIKON A1R/STORM machine. The multi immersion objective is removed from the turret but will remain available for users (ask CCI staff if you prefer to use it). The new objective is more widely applicable, has a working distance of 1 mm, a NA of 0.75 and should work well with the perfect focus system. We will test it in the coming period.

Microfluidic/Organ-on-a-Chip platform UU

Roos Masereeuw (Dept Farmacy) and Bart Gadella (Fac Vet Med) took the initiative to arrange a kick-off meeting for a consortium within the UU community to combine expertise on microfluidic device fabrication and developments in (combined) organ(s) on a chip. The FVM dean, Wouter Dhert  (who represents the joint life sciences faculties) gave a highly motivated talk to get this initiative started to: 1) get better disease models to test treatments, 2) reduce animal use for drug testing, 3) better model the complexity of (human) disease. In different animal models, Bart Gadella explained that correct in vivo fertilization in a fabricated mold that was coated with differentiated oviduct epithelia resemble replanted fertilized embryos efficiencies better (i.e. less polyspermia and better early embryonal development) than standard IVF. Roos Masereeuw explained her work on renal proximal tubuli endothelia in different biofabricated support systems to each measure aspects of the renal transport processes. She stressed that existing animal model systems have relatively poor predictable value for renal toxicity as is clear from experimental drugs that are rejected in the later phases of clinical trials. OOC systems have a great  promise to outperform animal testing models. Pedro Costa explained the capabilities of the biofabrication facility at the RMCU  to design (in a user friendly interface) and manufacture biological culture models in complex structural design and in different biological sample mixtures.

In the discussion, Roos noted the Brain-on-a-Chip meeting that is planned in next week (link). A regular meetup of the UU initiative will be planned and a questionnaire to monitor interests in the UU community is going to be circulated. Collaboration with a national intiative (hdmt) will be investigated .

BioImaging Utrecht Fall Meeting 2016: Tuesday 29th of November
