How do I notify all stores associated with a model after calling MyApp.MyModel.load()

How do I notify all stores associated with a model after calling MyApp.MyModel.load()? Alternatively, is there a way to load 1 record by Id from the context of a store?

My ultimate goal is to fetch one single record from the server and refresh a list that is bound to a store that has the record in it.
