ADAM metalloprotease function during embryonic Development
1 Our last manuscript accepted in DB “ADAM13 cleavage of Cadherin-11 promotes CNC migration independently of the homophilic binding site.”. 2 Helene is giving a talk at the GRC on placode and neural crest. 3 Dom is giving a talk at the GRC on Matrix metalloproteases.
The following movies show cranial neural crest cell migration in vivo (in the embryo) or in vitro (In a dish). In vivo the neural crest were labeled with a fluorescent marker before they were grafted into a host embryo.
How does a cell move? Cells move all the time in our bodies, to repair wounds, to attack pathogens, to fight cancer or in some cases to allow cancer to spread and invade new organs. In embryos, cells move great distances to produce the various shapes and complex organs.
We study how cells move in a developing embryo. More specifically, how do they start? How do they know where to go, where and when to stop? One of the best examples of cell movement (see movie) is the migration of cranial neural crest cells. They are borne at the border between the neural and non-neural ectoderm in the dorsal side of the embryo and migrate to the ventral side of the embryo to create all of the structures of the face (bones, cartilage, muscle and ganglia).
Our laboratory is funded by the NIH (NIDCR) to understand how metalloproteases that are expressed at the surface of the cranial neural crest help these cells move. We aim to understand which proteins are cut by these proteases and how this cleavage changes the function of these target proteins to favor cell movement. Clearly if these proteases can promote cell migration in the embryo, they may also promote cancer cell dispersion (Metastasis) so that understanding how they work and how we can stop their function may also lead to new approaches to cancer treatment.
