[Star Wars] What exactly did they take from Jango Fett to make his clones?

Was it blood? A Hair Sample? Cheek swab? How much did they need? Did he have to come back to donate more later on?

It's not specified, but it's likely blood, tissue samples and bone marrow. He did in fact had to regularly return to supply additional samples, which was plot point in Clone Wars - since there was no more any Jango Fett, kaminoan cloners faced an issue that their supply is limited.
