Transglutaminases (TGs) stabilize proteins by the formation of ε(γ-glutamyl)lysine cross-links. Here, we demonstrate that the cross-linking of collagen I (COL I) by tissue transglutaminase (TG2) causes an alteration in the morphology and rheological properties of the collagen fibers. Human osteoblasts (HOB) attach, spread, proliferate, differentiate and mineralize more rapidly on this cross-linked matrix compared to native collagen. When seeded on cross-linked COL I, HOB are more resistant to the loss of cell spreading by incubation with RGD containing peptides and with α1, α2 and β1 integrin blocking antibodies. Following adhesion on cross-linked collagen, HOB show increased phosphorylation of the focal adhesion kinase, and increased expression of β1 and β3 integrins. Addition of human bone morphogenetic protein to HOB seeded on TG2 cross-linked COL I enhanced the expression of the differentiation marker bone alkaline phosphatase when compared to cross-linked collagen alone. In summary, the use of TG2-modified COL I provides a promising new scaffold for promoting bone healing. © 2014 Springer-Verlag.

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.
