title: Hematopoiesis on cellulose ester membranes (CEM). VIII. Studies of the hematopoietic microenvironment developing on intraperitoneally implanted CEM in S1/S1d and S1+/S1+ mice.
abstract: Cellulose ester membranes (CEM) were implanted intraperitoneally into S1/S1d and S1+/ S1+ mice. These CEM rapidly became coated with peritoneal cells capable of supporting primarily granulocytic colony development after seven days. S1/S1d-coated CEM showed a diminished capacity to support colony development compared with S1+/ S1+ CEM, perhaps reflecting the defect in the hematopoietic microenvironment of these mice. Marrow cells from S1+/S1+ and S1/S1d mice generated similar numbers of colonies on S1+/S1+ CEM. When CEM were transferred from a primary to a secondary host there was a tendency to remodel the CEM toward the characteristics of the secondary host. Peritoneal cells coating CEM from S1/S1d mice had less phagocytosis of yeast particles than peritoneal cells from S1+/S1+ mice. The cell coat on the membranes from S1/S1d mice was fewer cell layers in thickness than those on membranes coated in S1+/ S1+ mice.
