title: Mucus secretion-stimulating activity in human lymphoblastoid cells.
abstract: Two fractions isolated from cultured lymphoblastoid cells stimulated mucus secretion from the urn cell complex of the marine invertebrate Sipunculus nudus. The activity detected in the nuclear fraction was trypsin-sensitive, and it increased in response to specific nucleotides.
