Two inherent challenges in the mechanistic interpretation of protease-deficient phenotypes are defining specific substrate cleavages whose reduction generates and determining whether result from loss function, accumulation, or a function(s) embodied fragments. Hence, recapitulation phenotype by cleavage-resistant would stringently validate importance proteolytic event clarify underlying mechani...

Collective cell migration is a common feature in both embryogenesis and metastasis. By coupling studies of neural crest migration in vivo and in vitro with mathematical modeling, Szabó et al. (2016, J. Cell Biol., http://dx.doi.org/10.1083/jcb.201602083) demonstrate that the proteoglycan versican forms a physical boundary that constrains neural crest cells to discrete streams, in turn facilitat...

A critical limitation in the cultivation of cartilage for tissue engineering is the dedifferentiation in chondrocytes, mainly during in vitro amplification. Despite many previous studies investigating the influence of various conditions, no data exist concerning the effects of hypothermia. Our aim has been to influence chondrocyte dedifferentiation in vitro by hypothermic conditions. Chondrocyt...
