Process for replicating bone marrow and other tissues in vitro and using the same

Abstract From the Canadian patent

A process for treating a person whose bone marrow has been destroyed or has lost its functional ability which, includes the steps of obtaining bone marrow from a donor replicating the bone marrow cells in vitro and then, reinfusing the replicated marrow cells at a later date. The bone marrows may be cryopreserved before and/or after the replication step. The in vitro bone marrow replication system may also be used to monitor a patient's condition or the cytotoxicity of various agents. Three-dimensional cell culture systems for the growth of at least two layers of cells for cell types in, addition to bone marrow cells may also be established using, a three-dimensional support as a framework.
