Two hundred U/kg of rhEpo were administered i.v. four or nine times every two weeks for six weeks. Phlebotomies (25 ml/kg of body weight) were conducted three times at two-week intervals. rhEpo was found to successfully prevent and correct anemia caused by the phlebotomies.

However, PHA-LCM prepared in the presence of a human leukocyte interferon preparation does not support mixed colony formation. Crude PHA-LCM preparations were characterized by gel filtration, affinity chromatography, and gel electrophoresis. The elution profile on Sephacryl S-300 of PHA-LCM prepared without interferon showed a distinct peak that stimulated the growth of pluripotent stem cells (CFU-gemm) and committed precursors (CFU-c, BFU-e). Gel filtration of PHA-LCM, prepared with 1000 U/ml of interferon, revealed a change in the elution profile. The eluted material demonstrated no growth-promoting activities. We conclude that the abolished stimulatory activity of PHA-LCM, prepared with human leukocyte interferon, might be due to a reduced production of stimulatory molecules, suggesting that interferon interferes with the molecular events required for colony formation of committed and noncommitted hemopoietic progenitors.</p>","PeriodicalId":13742,"journal":{"name":"International journal of cell cloning","volume":"2 5","pages":"286-95"},"PeriodicalIF":0.0,"publicationDate":"1984-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17550679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cells proliferate in suspension and do not aggregate or attach to the culture dish. Surface marker analysis revealed that the cells were negative for E-rosette, and surface immunoglobulin. Immunoelectrophoresis, immunodiffusion, and immunofluorescence with various antibodies demonstrated no heavy chains, while lambda-light chains were detected in the cytoplasm of the cells. Using the immunodiffusion technique, only lambda-light chains were detected in the frozen and thawed cell extract, the concentrated supernatant of the cell culture, and the urine of the patient. Electron microscopic examination revealed the plasmablastoid appearance of the cells.

The frequency of colony formation was significantly increased for cells grown in boiled agar in 8 samples (47%), unchanged in 8 samples (47%), and decreased in only one sample (6%). There were increases in both cluster and colony formation for the melanomas which had augmented colony formation when grown in boiled agar. There was also qualitative morphological improvement, including rounder, smoother cells and less extracellular debris surrounding the colonies. These data suggest that melanoma colony formation is enhanced when cells are grown in agar which has been sterilized by boiling rather than autoclaving.</p>","PeriodicalId":13742,"journal":{"name":"International journal of cell cloning","volume":"1 2","pages":"85-91"},"PeriodicalIF":0.0,"publicationDate":"1983-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17426175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
