Golang concurrency: how to append to the same slice from different goroutines

I have concurrent goroutines which want to append a (pointer to a) struct to the same slice. How do you write that in Go to make it concurrency-safe?

This would be my concurrency-unsafe code, using a wait group:

var wg sync.WaitGroup
MySlice = make([]*MyStruct)
for _, param := range params {
    go func(param string) {
        defer wg.Done()
        OneOfMyStructs := getMyStruct(param)
        MySlice = append(MySlice, &OneOfMyStructs)

I guess you would need to use go channels for concurrency-safety. Can anyone contribute with an example?
