Exact analyses of single cells based on the Fisher four-field hypergeometric distribution test with the Exacon procedure:
Antitypes (observed < expected)
^c = observed values lower than expected, p < .01
^d = observed values lower than expected, p < .001
Types (observed > expected)
^e = observed values higher than expected, p < .01
^f = observed values higher than expected, p < .001
