Adhesiveness benign cells

Each of these tumors produces CK, and each may produce transthyretin. A transitional zone between papilloma and carcinoma of the choroid plexus confirms choroid plexus carcinoma. Primary carcinoma of the choroid plexus so closely resembles metastatic carcinoma that the latter must be carefully excluded before the diagnosis of primary choroid plexus carcinoma can be made. Occult pulmonary or gastrointestinal primary tumors are common sources. The paucity of these primary systemic carcinomas in children facilitates diagnosis of choroid plexus carcinoma in a patient in this age group. Some choroid plexus carcinomas express CD44 cell adhesion molecule not seen in the most benign papillomas. The mean MIBl LI of choroid plexus carcinomas... 

There are number of material properties which must be considered prior to encapsulation of the cells [2,16]. Primarily precursor materials as well as their end products should be cytocompatible. The inner layer of the matrix should provide adhesion signals for attachment of adherent cells while the outer layer of the matrix should not elicit host inflammatory response. Encapsulation process should preferably be carried out under benign conditions. The membranes should have adequate tensile and...
