Amebocyte-producing organs (APOs) of Biomphalaria glabrata were maintained in nonnutritive saline with, or without, extracts of miracidia and adults of Schistosoma mansoni, and examined histologically. The hematopoietic cells remained viable and showed measurable mitotic activity for up to 6 days, with little evidence of tissue death. APOs accumulated fluid and became swollen by as soon as 24 hr, but no cell exomigration was observed. Parasite extracts elicited an increase in the number of dividing cells in the APO, suggesting that the extract may directly stimulate a response from the hematopoietic cells by providing either nutrients or mitogenic growth factors.
